Functions and System Configuration Chapter 1 1-1 Functions

The 3G3FV-PDRT1-SIN CompoBus/D Communications Card is a dedicated communications interface
card that makes it possible for the SYSDRIVE 3G3FV High-function General-purpose Inverter to com­municate with SYSMAC Programmable Controllers. Installing a CompoBus/D Communications Card in
the SYSDRIVE 3G3FV Inverter permits a Programmable Controller to monitor RUN/STOP and operat­ing conditions, and to make changes in set values.

3G3FV-PDRT1-SIN
CompoBus/D Communications Card

H Easy Communications

The following two functions can be used simultaneously in CompoBus/D communications between the
CPU Unit of a SYSMAC PC and the SYSDRIVE 3G3FV Inverter.

S Remote I/O Communications

I/O is automatically transferred between Slaves and the CPU Unit without any special program­ming in the CPU Unit. (Automatically transmits Inverter control inputs such as RUN or STOP from
a SYSMAC PC to the SYSDRIVE 3G3FV Inverter and returns operation status of the Inverter or
output frequency monitor data. )

S Message Communications

Message communications are performed between a CPU Unit to which a Master Unit is mounted
and Slaves (SYSDRIVE 3G3FV Inverters) by executing specific instructions (such as CMND
and IOWR, depending on the model of SYSMAC PC used) from the program in the CPU Unit.
(Allows some parameter setting and monitoring, Inverter output frequency, output voltage, or
output current. If the remote I/O communications is not performed, Inverter control data such as
RUN or STOP can be input through this message communications function.)

Remote I/O communications for the CompoBus/D Communications Card are performed using either 4
or 6 words allocated in the I/O Area of the SYSMAC PC. The Inverter can be controlled using remote I/O
communications because the basic control I/O functions, frequency setting functions, and output fre­quency monitoring functions are assigned to remote I/O. The allows the Inverter to be controlled
through simple I/O processing.

H Communications with SYSMAC C200HX/HG/HE and CV-series PCs

The CompoBus/D communications system is supported by both SYSMAC C200HX/HG/HE and CV-se­ries Programmable Controllers. Up to twice as many Inverters can be connected in comparison to SYS­MAC BUS Remote I/O Systems to support even larger control systems.

Note 1. The maximum number of nodes that can be connected to the system depends on the type of

Master Unit used, whether the message function is used, and the number of words used by
remote I/O communications. See 1-3 CompoBus/D System Configuration for further details.

Functions and System Configuration Chapter 1

Note 2. The SYSMAC CV Series includes the CV1000, CV2000, and CVM1 Programmable Control-

lers. SYSMAC C200HS PCs support only remote I/O communications.

H Multi-vendor Network

The CompoBus/D conforms to the DeviceNet open field network specification, which means that de­vices (Masters and Slaves) produced by other manufacturers can also be connected to the Network.
The CompoBus/D Communications Card supports the DeviceNet AC/DC drive object, so that the func­tions available for CompoBus/D communications can be used in DeviceNet communications.

H Choice of Communications Functions

The CompoBus/D Communications Card has various functions to choose from to suit the Inverter ap­plications.

S Remote I/O Communications

Either basic remote I/O control or special remote I/O can be chosen for remote I/O allocation to
suit the application. Special I/O control can be used to control and set all functions for 3G3FV -se­ries Inverters.

S Message Communications

Basic Inverter control and monitoring is possible with DeviceNet explicit messages, which are
defined for AC/DC driver objects. Remote I/O and message communications can be used simul­taneously, i.e., remote I/O control can be performed at the same time as other control using mes­sage communications.

Functions and System Configuration Chapter 1

H Applicable to Various System Configurations

Remote I/O communications and message communications are available as communications func­tions. Normal control inputs are controlled by the remote I/O communications function. When neces­sary, the message communications function is used to monitor each Inverter. It is possible to control the
selection of either the communications control input or local control input provided that the Inverter soft­ware version is higher than Ver. 1042.

Note For connecting the CompoBus/D Communications Card of the Inverter, use DCA1-5C10 Thin

Cables and branch them from the T-branch Tap.
Thick Cables cannot be used for this kind of wiring because of the terminal block dimensions.
As for multi-drop wiring, use Thin Cables for direct insertion. Thick Cables cannot be used for this
kind of wiring.

H Multi-vendor Network

The CompoBus/D conforms to the DeviceNet open field network specification, which means that de­vices (Masters and Slaves) produced by other manufacturers can also be connected to the Network.
Therefore, a wide range of field-level applications can be supported by combining valve devices, sen­sors, and other devices.

H Simultaneous Remote I/O and Message Services

Remote I/O communications to constantly exchange I/O data between the PC and Slaves can be
executed simultaneously with message communications, to send/receive Master Unit data as required
by the application. Therefore, a CompoBus/D Network can be installed to flexibly handle applications
that require both bit data and message data. Message communications can be achieved either by using
OMRON’s FINS commands or by using DeviceNet explicit messages.

H Connect Multiple PCs to the Same Network

A Configurator (sold separately) can be used to enable connection of more than one Master to the Net­work, allowing message communications between PCs and between multiple groups of PCs and
Slaves. This allows the CompoBus/D Network to be used as a common bus to unify controls while re­ducing wiring.

H Handle Multi-point Control and Line Expansions with Multi-layer

Networks

A Configurator (sold separately) can be used to enable mounting more than one Master Unit to a single
PC, allowing control of many more points. This feature can easily handle line expansions and other ap­plications.

H Free Remote I/O Allocation

A Configurator (sold separately) can be used to enable flexible allocation of I/O, i.e., in any area and in
any order. This allows I/O allocations that suit the application to simplify programming and enable effec­tive usage of PC memory areas.

H Handle Slaves with Different Response Speeds

A Configurator (sold separately) can be used to set the communications cycle time, enabling usage of
Slaves with slow response times.

H Easily Expand or Change Lines with Various Connection Methods

Use a multi-drop trunk line, T-branch multi-drop lines, or daisy-chain drop lines. All three connection
methods can be combined to flexibly construct a Network that meets the needs of the application.

Note For connecting the CompoBus/D Communications Card of the Inverter, use DCA1-5C10 Thin

Cables and branch them from the T-branch Tap.

Functions and System Configuration Chapter 1 1-3 CompoBus/D System Configuration

1-3-1 System Configuration

CompoBus/D is a multi-bit, multi-vendor network that combines controls and data on a machine/line­control level and that conforms to DeviceNet open field network specifications.

Two types of communications are supported: 1) Remote I/O communications that automatically trans­fer I/O between Slaves and the CPU Unit of a SYSMAC PC without any special programming in the CPU
Unit and 2) Message communications are performed between a CPU Unit to which a Master Unit is
mounted and Slaves by executing specific instructions (such as CMND and IOWR, depending on the
model of SYSMAC PC used) from the program in the CPU Unit.

A Configurator (sold separately) can be used to enable following. This allows the support of an even
larger control system.

S I/O area words can be flexibly allocated for remote I/O communications.
S More than one Master Unit can be mounted to a single PC.
S More than one Master Unit can be connected in a single Network.

1-3-2 Configurator Overview

The Configurator is software application run on an IBM PC/AT or compatible computer and is used to
support a CompoBus/D communications system. OMRON provides interfaces (hardware) for connect­ing computers to the CompoBus/D Network. The Configurator occupies one node on the CompoBus/D
Network, but has no specific functions on the network itself. The Configurator provides the following
functions.

S Free Allocation of Remote I/O

The remote I/O allocations in the PCs can be changed from the Configurator. I/O can be flexibly
allocated for each node within the specified I/O areas.

S More than One Master Unit per Network

Slaves can be set for each Master Unit from the Configurator enabling communications between
multiple groups of PCs and Slaves. The maximum number of nodes connected to one Network
remains at 64. One Slave can be connected to no more than one Master Unit.

1-8

Functions and System Configuration Chapter 1

S More than one Master Unit per PC

Remote I/O can be allocated for each Slave of the Master Unit from the Configurator, so more
than one Master Unit can be mounted to the same PC.

Note In allocating Remote I/O for each Master Unit, be careful not to allow any dual allocation.

2-1-1 Network Components

H Nodes

There are two kinds of nodes on a CompoBus/D Network: The Master and Slaves. The Slaves connect
to external I/O and the Master administers the Network and manages the external I/O of the Slaves. The
Master and Slaves can be connected at any location in the Network, as shown in the preceding diagram.

H Trunk/Drop Lines

The trunk line refers to the cable that has Terminating Resistors on both ends. Cables branching from
the trunk line are known as drop lines. The trunk line length does not necessarily coincide with the maxi­mum length of the Network. CompoBus/D communications are transmitted through 5-wire cables. The
cables come in thick and thin versions.

H Connection Methods

Two methods can be used to connect CompoBus/D nodes: The T-branch method and the multi-drop
method. With the T-branch method, the node is connected to a drop line created with a T-branch Tap.
With the multi-drop method, the node is directly connected to the trunk line or the drop line. Secondary
branches can be made from a drop line. Both of these connection methods can be used in the same
Network.

H Terminating Resistors

Terminating Resistors are connected at each end of the trunk line to reduce signal reflection and stabi­lize communications. There are two kinds of Terminating Resistors available: One that is provided with
a T -branch T a p and a Terminal-block Terminating Resistor. Use a CompoBus/D Cable when connecting
a Terminal-block Terminating Resistor.

H Communications Power Supplies

To use CompoBus/D, connect a communications power supply to the communications connector of
each node with a 5-wire cable. Basically, a communications power supply, internal circuit power supply,
and I/O power supply must be provided separately.

2-2

CompoBus/D Communications Line Design Chapter 2 2-1-2 Connections

H Trunk and Drop Lines

The trunk line is a cable to which Terminating Resistors are connected at the ends. Drop lines are cables
that branch from the trunk lines. A special 5-wire cable is used for both the trunk lines and the drop lines.

CompoBus/D Communications Line Design Chapter 2 2-2 Network Configuration Restrictions

CompoBus/D communications are designed to meet a wide range of applications by providing a choice
of baud rates and allowing different combinations of T-branch and multi-drop connections. The restric­tions of CompoBus/D communications that are required to enable the various communications possibi­lities are described here.

2-2-1 Baud Rate and Communications Distance

The maximum length of the CompoBus/D communications cables is restricted by the baud rate and the
type of cable used. The three types of restrictions on CompoBus/D communications cable length are as
follows:

S Maximum network length
S Drop line length
S Total drop line length

Be sure to design and configure a Network that meets the conditions provided below to ensure reli­able communications.

H Maximum Communications Distance

length

H Maximum Network Length

The length of the Network is longest at either the distance between the two most distant nodes or at the
distance between the Terminating Resistors.

There are two types of cables: Thick Cables and Thin Cables. The cable thickness affects signal deteri­oration. The maximum length of the Network therefore depends on the type of cable used as shown in
the previous table.

The following restrictions apply to Networks in which both Thick and Thin Cables are combined.

Baud rate Maximum Network length

500 kbps
250 kbps
125 kbps

Thick Cable length + Thin Cable length x 100 m
Thick Cable length + 2.5 Thin Cable length x 250 m
Thick Cable length + 5.0 Thin Cable length x 500 m

H Drop Line Length

The length of the drop line is measured from the point in the trunk line where the original branch was
made to the end of the branch. The maximum length of a drop line is 6 m. It is possible to make a second­ary branch from a drop line.

2-4

CompoBus/D Communications Line Design Chapter 2

H Total Drop Line Length

The total drop line length is the total sum length of all the drop lines (but not including the trunk line). Do
not exceed the maximum total drop line length (even when the length of each individual drop line is 6 m
or less). The standard for the total drop line length varies with the baud rate as shown in the previous
table.

and the total drop line length.

When there is a T-branch Tap 6 m or less from the end of the trunk line (or the node):

A Terminating Resistor attached to a T-branch Tap can easily be mounted without taking up much
space.

When there is not a T-branch Tap 6 meters or less from the end of the trunk line (or the node):

A Terminating Resistor must be connected before that point. Either a T-branch Tap mounted to a
Terminating Resistor or a terminal block with Terminating Resistor can be used. In this case, be sure
to make the cable length 1 m or less from the node to the Terminating Resistor.

CompoBus/D Communications Line Design Chapter 2 2-3 Communications Power Supply

2-3-1 Locating the Communications Power Supply

H Basic Concept

•The communications power supply must be 24 VDC.

•Make sure that the power is supplied from the trunk line.

•When providing power to several nodes from one power supply, if possible try to locate the nodes in

both directions from the power supply.

•Provide power through Power Supply T aps. It is, however, possible to use T -branch Taps instead when
there is one communications power supply in the system and the total current consumption is less
than 5 A.

•The power supply capacity for cables is restricted to 8 A for Thick Cables and 3 A for Thin Cables.

•A single Network is usually supplied by one power supply. It is, however , possible to have more than

one power supply when power supply specifications cannot be met with a single power supply. (See
2-3-4 Step 3: Splitting the System into Multiple Power Supplies.)

•Fully consider the power supply capacity allowance in the design.

•If the power supply is switched OFF during the operation of the Network, there may be a malfunction in

the nodes.

•The current capacity of the drop line varies according to its length. The longer the drop line, the lower
its maximum capacity becomes. This is the same whether the cable is thick or thin. Calculate the cur­rent capacity passing through the drop line I (the total current consumption at the drop line) using the
following formula.

I = 4.57/L I: Permissible current (A)

L: Length of the drop line (m)

Note 1. If power supply specifications cannot be met with a single power supply when the current ca-

pacity of the Thick Cable exceeds 8 A even after the power supply location is modified, use
more than one communications power supply.

Note 2. In configuration 1, the power can be supplied in two directions to the trunk line as long as the

current capacity of each is 8 A or less when using Thick Cable, i.e., it is possible to have a
configuration with a total maximum current capacity of up to 16 A.

2-8

CompoBus/D Communications Line Design Chapter 2

Note 3. Consider changing to Thick Cable to meet specifications if the current capacity of the Thin

Cable exceeds 3 A when using Thin Cable for the trunk line.

H Setting the Power Supply Location

Determine whether or not the current can be supplied normally by finding the current capacity required
by each node and the voltage drop in the cables to be used to provide power. Calculate the values below
in advance.

•The current capacity required by each node

•The distance between the power supply and each node

The current capacity of the 3G3FV-PDR T1-SIN CompoBus/D Communications Card is approximately
20 mA.

H Calculating the Power Supply Location

There are two methods to find the best location of the communications power supply on the trunk line.

•Simple calculation from a graph

•Calculation by formula (Calculating the voltage drop from resistance and current consumption of the

communications cables).

Each drop line must satisfy the equation on page 2-6, which represents the relationship between the
drop line length and the current capacity for the drop line.

Note 1. From the graph, a hypothetical power supply location can be determined if the conditions cal-

culated in the graph are met by estimating the worst configuration (that has the maximum volt­age drop as shown in the diagram below).

Node

Node

Note 2. Even if the power supply specifications cannot be met using the graph, the conditions can be

met and a hypothetical power supply location determined by using the formula.

Note 3. When the communications power supply and the internal circuit supply are the same, use the

formula to calculate a hypothetical power supply location because it cannot be determined by
using the graph.

2-3-2 Step 1: Determining the Best Location for the Power

Supply from a Graph

A voltage drop occurs when a current flows through a communications cable. The longer the commu­nications cable and the larger the current, the greater the voltage drop. The communications power
supply at each node must be 11 VDC or more. To ensure the correct power supply, the relationship is
plotted as shown in the following graph to find the maximum current that satisfies the voltage of the
communications power supply at different trunk line lengths even if there is a voltage drop due to cable
resistance.

H Determining the Best Location of the Power Supply from a Graph

Verify the Items 1 to 3 below for each node located in the same direction viewed from the power supply.
Therefore, if nodes are located on both sides of the power supply, these items must be verified for all
nodes located in each direction.

1 Find A, the total current consumption of all the nodes to which communications power is to be sup-

plied.

2 Using the graph compute B, the maximum current flow in each cable from the power supply to the

end of the trunk line according to the types of cables (Thick Cables or Thin Cables).

2-10

CompoBus/D Communications Line Design Chapter 2

3 Compare the values found in steps 1 and 2, above. If the first value (A) is less than the second (B),

this shows that power supply specifications are met and power can be supplied to all nodes at any
point in the Network.

Note Be sure to refer to the correct graph as the maximum current flow is different for Thick and Thin

Cables.

H Countermeasures

If the second value (B) is less than the first (A), use the following procedure to locate the communica­tions power supply.

•Locate the communications power supply in the center of the Network and the nodes to both sides of it.

•If the nodes are already located at both sides of the power supply, move the power supply in the direc-

tion that requires the larger current capacity.

•If Thin Cable is being used, replace it with Thick Cable.

Note If, after following the above procedure, B is still less than A, go to Step 2 and determine the actual

position of the nodes by the formula calculation method.

D Calculation Example

The following example shows a Network that requires power to be supplied for 240 m on Thick Cable.
The power supply is located in the center of the Network. Because the power supply is in the center, the
maximum current will flow both to the left and to the right, enabling the supply of at least twice the maxi­mum current as when the power supply is placed on the end of the Network. The current consumption
for individual nodes is as follows:

Maximum current for the left side of the Thick Cable (see previous table) = approx. 2.5 A

(using straight line approximation between 100 to 150 m)

2-3-3 Step 2: Calculating the Best Location of the Actual

Nodes

Go to Step 2 if the best location for the power supply according to the specifications cannot be deter­mined from the graphs. The second method calculates the best location for each actual node and does
not estimate the worst possible configuration for the power supply.

2-11

CompoBus/D Communications Line Design Chapter 2

Basically , i n the CompoBus/D Network the permissible maximum voltage drop within the system can be
specified at 5 V for a power supply line (+V or –V), by calculating the specifications for the voltage of the
communications power supply (24 VDC) and the input voltage of the communications power supply of
each device (11 to 25 VDC).

Of the permissible 5-V maximum voltage drop within the system, the permissible voltage drop is 4.65 V
in the trunk lines and 0.35 V in the drop lines.

The following formulae are applicable when power is supplied independently for communications
and the internal circuit. For details on voltage drop and formulae when the communications power
supply and internal circuit power supply are shared, refer to the CompoBus/D (DeviceNet) Opera-
tion Manual.

H Formulae

Try to calculate the best location for each node using the formula below. If the best location for each
node can be determined using the formula, the specifications for the power supply to each node can
also be met. Do not exceed the maximum current capacity of the cable (Thick Cable: 8 A and Thin
Cable: 3 A).

Note If there are nodes on both sides of the power supply, the formula is used to calculate the best

conditions are satisfied if the following equations are true.

2-3-4 Step 3: Splitting the System into Multiple Power Supplies

Go to Step 3 if the best location for the nodes cannot be calculated from the formulae. In the third step,
there are multiple power supplies and the power supply system is split.

H Splitting the Power Supply System

•Be sure to use a Power Supply Tap for each power supply when the Network is supplied by two or more
power supplies.

•Remove the fuses in the Power Supply Tap to split the power supply system.

Once the power supply system is split, return to Step 1 or 2, and determine the best location of the nodes
in each system.

CompoBus/D Communications Line Design Chapter 2 2-3-5 Dual Power Supplies

Because diodes are contained in Power Supply Taps, these taps can be used to construct a dual power
supply system in the Network. Dual power supply differs from parallel operation of power supplies, so
the following restrictions apply.

H Restrictions

Dual power supply is basically used to ensure backup power supply, not parallel operation of power
supplies. Therefore, each power supply to be used must meet the power allocation specifications (i.e.,
must satisfy steps 1 and 2).

2-14

CompoBus/D Communications Line Design Chapter 2 2-4 Communications Line Noise Prevention

2-4-1 Communications Line Noise

The communications line sends and receives high-speed pulse signals, and checks whether the data is
correct by checking the sequence of the signals. If the amount of noise on the communications line is too
great, the interference will alter the communications signal data, and communications will be impossi­ble. Communications lines are more sensitive and require higher speeds than normal I/O lines, so be
sure that noise does not interfere with communications. Use the preventative noise countermeasures
described here when configuring the system to ensure smooth system start up.

2-4-2 Grounding the Network

H Grounding the Network

The CompoBus/D Network must be grounded at only one location so that a ground loop is not created.
The ground should also be connected as close as possible to the center of the Network. Connect the
cable shield to the ground terminal on the communications power supply and then connect to a ground
of 100 Ω max., as shown in the following diagram.

If more than one communications power supply is connected to the same Network, ground only the one
nearest the center of the Network. Do not connect the shield wire at the other power supplies.

Note 1. Always ground the communications cable shield at one and only one location in the Network.
Note 2. Always ground to 100 Ω or less.
Note 3. Always use a separate ground. Never use the same ground as for Inverters or other drive

system devices.

H Grounding the CompoBus/D Communications Card

The CompoBus/D Communications Card should be grounded according to DeviceNet recommenda­tions installing a noise filter as shown in the following diagram. The ground is normally wired to the
ground terminal (12 (G)).

nect the grounding cable.

2-4-3 Communications Power Supply Noise Prevention

The communications power supply is the most important power supply in a CompoBus/D Network. The
following measures will prevent noise in the communications power supply.

•Use the recommended power supply (S82H/S82J) for communications.

•Use an independent power supply for communications.

•Make sure to install a noise filter on the primary AC input side of the communications power supply.

•Always use a control system power supply for the primary AC side of the communications power sup-

ply that is not shared with power devices, such as Inverters or motors.

If noise interference remains in cables for which noise countermeasures have been implemented, the
following countermeasures may be effective.

D Communications Cable Shielding

Suspend the communications cable shielding wire without grounding it. This will filter the noise that
flows from the ground to the communications cable and will filter the noise current that flows in the
shielding wire.

D Communications Power Supply

Suspend the communications power supply without grounding it. This will also filter the noise that flows
from the communications power supply ground to the communications cable or the noise current that
flows in the shielding wire. The switching power supply is usually connected to the case and the capaci­tor as shown below. The ground (FG) terminal must be suspended and the control panel for the power
supply itself must be insulated.

2-4-4 Noise Prevention Wiring

To prevent inductive noise, do not wire the communications line, SYSMAC power lines, and other power
lines near to each other. Keep the power lines for Inverters, motors, regulators, and contactors, the
communications lines, and the SYSMAC power lines separated from each other by at least 300 mm.
Also, provide separate conduits or ducts for the communications lines and power lines.

•Do not install communications lines and SYSMAC power lines onto the control panel on which high­voltage devices are mounted.

•Because noise currents flow through metallic equipment (such as casings), the communications
cables should be placed as far away from metallic equipment as possible.

•Ground the shielding wire on the communications cable at one point.

•If the same ground is used for the communications cables and communications power supply, there is

a possibility that noise may be transmitted through the ground line to the communications line. In order
to avoid this, be sure that the power line ground and the grounds for the communications cables and
the communications power supply are located as far from each other as possible.

remote I/O is allocated in the order of CompoBus/D node addresses and the words are divided into out­put areas and input areas. The word allocation default settings of the Master Unit are set based on the
assumption that one node should occupy one input word and one output word. Output words will be
allocated even to Units that are used only for input.

For Units that require two input words or two output words, the node addresses to which the second
word is normally allocated cannot be set. If it is set, the word allocations will overlap.

Each node address is allocated one input and one output word starting from node 00. If a Slave requires
more than one input or one output word, then it is assigned more than one node address. If a Slave
requires less than one word, it simply uses the rightmost bits in the word allocated to it.

H Free Allocation: With Configurator

A Configurator can be used to allocate words in the CompoBus/D Master Unit in any order by calling
parameters of the Master Unit and changing the word allocation of parameters. The following alloca­tions are possible when using a Configurator.

•Output words do not need to be allocated to Input Units, only input words.

4-2

CompoBus/D System Startup Chapter 4

•Slaves that require two words can be allocated two words using only one node address so that the next
node addresses can be set for another Slave.

•Remote I/O words can be allocated in sequence regardless of the order of the node addresses.

Note The Configurator uses one node address. Therefore, the number of Slaves that can be connected

is reduced if the Network is to be operated with the Configurator still connected. The Configurator
can be removed, however, after the words have been allocated, and then another Slave can be
connected to the Network in its place so that the number of Slaves that can be connected is not
reduced.

Blocks can be positioned in any order in memory,
e.g., the following order is okay: input block 1, out-

Words are freely allocated to the Slaves and I/O blocks can be set as desired. Each node must be allo­cated at least one byte (leftmost or rightmost). If a Slave requires more than one input or one output
word, then it can be allocated more than one input or output word. If a Slave requires less than one word,
it will use either the rightmost or leftmost bits in the word allocated to it.

D Free Allocation Restrictions

The following restrictions apply when freely allocating remote I/O.

•The remote I/O allocated to one Slave cannot be separated, i.e., all input words must be consecutive,
as must all output words. Inputs and outputs, however, can be separated.

•With a Slave requiring more than one word, a series of allocations cannot be started from the leftmost
byte of the remote I/O. The leftmost byte, however, can be allocated to a Slave requiring only 8 bits.

•Multiple words cannot be allocated as the remote I/O for a single Slave.

•A Slave cannot be assigned to more than one Master Unit.

4-1-2 Scan Lists

H The Scan List

Scan lists record information in the Master Unit on the Slaves that are connected to them. If the scan list
is enabled, the information on each Slave is recorded, and can be used to determine normal Compo­Bus/D communications. The scan list provides the following information on each Slave.

4-3

CompoBus/D System Startup Chapter 4

•Slave remote I/O allocations providing the number of I/O words allocated to and the node address set
for each Slave.

•Communications parameters providing the initial remote I/O communications status and the commu­nications cycle time settings.

H Scan List Application

A scan list is not required for a Network with only one Master Unit and remote I/O that is allocated ac­cording to the fixed settings. The scan list is necessary, however, in the following cases.

•To confirm the increase or decrease of Slaves on the communications line, and to detect errors in a
Network where the number of Slaves has increased or decreased, it is necessary to record the system
status.

•For free allocation of remote I/O, it is necessary to record the number of I/O words allocated to each
Slave.

•When using multiple Master Units to exchange information with the SYSMAC PC (CPU Unit), it is nec­essary for each Master Unit to record the node addresses for each Slave.

H Creating Scan Lists

D Fixed Remote I/O Allocations

A scan list can be created by turning ON the Enable Scan List software switch when the CPU Unit is in
PROGRAM mode, when communications are active and the scan list is disabled. All Slaves that are
participating normally in the Network will be registered in the scan list.

D Free Remote I/O Allocations

The user creates the scan list using the Configurator and then registers it in the Master Unit. Settings for
all Masters and Slaves participating normally in the Network are used as a basis for creating the scan
list.

save any scan lists created with the Configurator as network files or master parameter files.

4-4

CompoBus/D System Startup Chapter 4

H Using Scan Lists

D Enabling/Disabling a Scan List

To enable a scan list, turn ON the Enable Scan List software switch or use the Configurator. To disable a
scan list, turn ON the Clear Scan List software switch.

Note 1. Scan lists cannot be disabled from the Configurator . The scan list will always be enabled when

created on the Configurator and registered in a Master Unit.

Note 2. Always enable the scan list during actual system operation. Although operation is possible

with the scan list disabled when the fixed allocations are used, communications will continue
even if Slaves fail, creating the possibility of undetected errors in system operation.

D Scan List Enabled

When a scan list is enabled, communications are performed according to the scan list stored in the Mas­ter Unit’s non-volatile memory. Either fixed allocation or free allocation of remote I/O is possible.

The Master will communicate only with the Slaves registered in the scan list. A verification error will
occur if a Slave registered in the scan list does not exist in the Network or is not started when I/O commu­nications begin. Even if it is properly connected in the Network, a Slave which is not registered in the
scan list will not participate in communications and will not be checked for errors.

D Scan List Disabled

When a scan list is disabled, communications are performed without using the scan list. The scan list is
disabled when the scan list has not been created or it has been cleared. Do not disable the scan list
during actual system operation.

All of the Slaves in the Network can communicate with the scan list disabled, so Slaves can be added to
the Network while communications are in progress. Without a scan list, however, there is no way to
check for Slaves that have not started or have failed, and errors can thus go undetected. The commu­nications cycle time will be much longer that the computational value when the scan list is disabled.

When a scan list is disabled, operation is possible only by using the fixed I/O allocations. Free allocation
is not possible.

Note 1. The scan list is automatically enabled when the Configurator is used to allocate remote I/O. If

the software switch is used to clear the scan list, remote I/O communications will operate un­der the default allocations with the scan list disabled. Always confirm that the system is
stopped before disabling the scan list in a Master Unit. This is particularly important if there is
more than one Master on the same Network. If the scan list is disabled for one of the Masters,
normally communications will not be possible.

Note 2. The scan list data in a Master Unit is deleted whenever the scan list is disabled.

4-1-3 Fixed Word Allocations

H Allocation Areas for Different PCs

If fixed allocations are used, the node addresses and the words allocated to them are determined ac­cording to the PC used. The remote I/O allocation area consists of the input area that receives input from
the Slaves, and the output area that writes output data to the Slaves.

Note 1. The words corresponding to the node address of the Master Unit are not actually used by the

Master Unit, so they can be used by other Slaves. The actual node address of the Master Unit,
however, cannot be the same as the node address of another Slave.

Note 2. When Slaves made by other companies are used that are for either output only or input only,

both the output area and the input area may be used depending on the status information.
Therefore, be sure to check the specifications of the Slave before using any word allocated to
a Slave.

H I/O Allocations and Errors

A setup error may occur when the scan list is disabled or a verification error may occur when the scan list
is enabled if I/O allocations are not correct.

D Setup Error: I/O Area Overlap

A setup error (I/O Area Overlap) will occur and it will not be possible to start CompoBus/D communica­tions if the same word is used by more than one Slave connected to a SYSMAC Master Unit. This error
will occur only when the scan list is disabled.
To eliminate the I/O area overlap and clear this error, change the node address setting on one of the
Slaves and restart the Master Unit by turning ON the power again or restarting.

D Setup Error: I/O Area Range Violation

A setup error (I/O Area Range Violation) will occur and it will not be possible to start CompoBus/D com­munications if node addresses are set at values that exceed the specified range, or if Slaves that use
multiple words are using more words than are specified in the I/O area. This error will occur only when
the scan list is disabled.
To eliminate the above problems and clear this error, change the node address setting on the Slaves
and restart the Master Unit by turning ON the power again or restarting.

4-6

CompoBus/D System Startup Chapter 4

D Verification Error: Slave I/O Size Differs

A verification error (Slave I/O Size Differs) will occur and it will not be possible to start CompoBus/D
communications if a Master Unit is being used with the scan list enabled and the type of I/O (input or
output) or the number of I/O points registered for a Slave in the scan list does not match the actual I/O
specifications of the Slave that is connected to the Master Unit. This error will occur only when the scan
list is enabled.
To eliminate and clear this error, either create the scan list again or replace the Slave with the kind of
Slave registered in the scan list.

Note The scan list verification is performed in byte units (8 bits). A verification error will therefore not

occur if a 1-point Input Slave is used instead of an 8-point Input Slave.

CompoBus/D System Startup Chapter 4

2. Set the initial settings for the Slaves:
Node address (DIP switch)

Baud rate (DIP switch)
Etc.

3. Mount the Master Unit and wire the Network.
For CV-series PCs, Master Units are treated as CPU Bus Units and can be mounted to the CPU

Rack or Expansion CPU Rack. Only one Master Unit can be mounted if a Configurator is not used,
but up to 16 Master Units can be mounted if a Configurator is used.

For C200HX/HG/HE PCs, Masters are treated as Special I/O Units and can be mounted to the CPU
Rack or Expansion I/O Rack. Only one Master Unit can be mounted if a Configurator is not used, but
up to 10 or 16 Master Units can be mounted if a Configurator is used.

For C200HS PCs, Masters are treated as Special I/O Units and can be mounted to the CPU Rack or
Expansion I/O Rack. Only one Master Unit can mounted if a Configurator is n o t used, but up to 10 or
16 Master Units can be mounted if a Configurator is used.

4. Connect a Programming Device to the PC and turn ON the power supply to the PC.

5. Generate the I/O table.

6. Turn ON the power supply to the Slaves and turn ON the communications power supply.

7. Switch the PC to PROGRAM mode.

8. Perform the following and go to step 11. if the scan list was disabled at startup.
a) Confirm that communications are possible with the registered slaves by monitoring the Regis-

tered Slave Data Area.

b) From a Programming Device connected to the PC, turn ON the Scan List Enable Bit in the soft-

ware switches (bit 0).

Remote I/O communications will start with the scan list enabled. The software switches can be used
to start and stop remote I/O communications.

9. Perform the following from the Programming Device connected to the PC and go to step 11. if the
scan list was enabled at startup and you want to re-register the scan list.

a) Turn ON the Scan List Clear Bit in the software switches (bit 1).
b) Confirm that communications are possible with the registered slaves by monitoring the Regis-

tered Slave Data Area.
c) Turn ON the Scan List Enable Bit in the software switches (bit 0).
Remote I/O communications will start with the scan list enabled. The software switches can be used

to start and stop remote I/O communications.

10. Do nothing if the scan list was enabled at startup and the scan list does not need to be changed.
Remote I/O communications will start with the scan list enabled. The software switches can be used

to start and stop remote I/O communications. Go to step 11.

11. Confirm that the MS and NS indicators on all Master Units and Slaves are lit.

12. Switch the PC to RUN mode.

5-1 Remote I/O

There are two types of CompoBus/D communications: Remote I/O and message communications.
There are three types of remote I/O operation: Basic remote I/O, standard remote I/O, and special re­mote I/O. This section explains standard remote I/O operations and the types of remote I/O.

Note To use special remote I/O, it is necessary to switch the remote I/O operation. Switching the remote

I/O operation involves the use of message communications, so refer to 5-2 Message Commu-
nications and 5-3 Switching Remote I/O Operations. Also, for details regarding special remote
I/O, refer to 5-4 Special Remote I/O.

a: Speed scale value of Class 2A, Instance 01, Attribute 16 (Initial value: 0)

• The speed scale is assigned to the message function. For instructions on how to change it, refer to 5-2 Mes-

sage Communications.

• The unit for the rotational speed reference is set in o1–03 (frequency reference setting and display units)

• Setting example (providing reference of 1,800 r/min):

When the speed scale value is “0” and the number of motor poles is set in 01–03 (so unit is r/min):

0

1,800 r/min → 1,800 x2

Note 1. Under the DeviceNet protocol, the unit for the speed reference is fixed as r/min. The number

of motor poles (2 to 32) must be set in parameter o1–03 (frequency reference setting and dis­play units) when using DeviceNet (open network).

Note 2. If the setting in not within the proper range, the previous data will be retained and the desig-

nated rotational speed will not be entered.

CompoBus/D Communications Card Operations Chapter 5 5-1-2 Types of Remote I/O Operation

There are three types of CompoBus/D Communications Card remote I/O operation:

•Basic remote I/O: Remote I/O operation for the standard DeviceNet configuration.

•Standard remote I/O: Remote I/O operation (DeviceNet-compatible) that is the default setting for the

CompoBus/D Communications Card.

•Special remote I/O: Remote I/O operations that enable using all the functions of 3G3FV-series Invert­ers, and accessing/setting for all parameters. (Special remote I/O operation is special for this product;
they are not compatible with DeviceNet.)

The default setting is for standard remote I/O operation, so it will be necessary to switch to either of the
other types of remote I/O operation if desired. Switching the remote I/O operation involves the use of
message communications. Refer to 5-2 Message Communications and 5-3 Switching Remote I/O Op-
eration.

CompoBus/D Communications Card Operations Chapter 5 5-2 Message Communications (DeviceNet Explicit Messages)

There are two types of CompoBus/D communications: Remote I/O and message communications. This
sections explains CompoBus/D Communications Card message communications. With message
communications, specific instructions (SEND, RECV , CMND, and IOWR) are used for reading and writ­ing data between Master and Slave Units.

5-2-1 Overview of Message Communications (Explicit Message

Operations)

H Message Communications Operations

Message communications enable data to be exchanged as required between nodes (i.e., between
Masters or between Masters and Slaves) on a CompoBus/D Network. For example, the accumulated
data from a given PC can be read from another PC, and constants from various Slaves can be changed
from a PC. To use message communications, however, both nodes involved in the data exchange must
support message communications.

Note: T-branch wiring using Thin Cables

H Types of Message Communications

CompoBus/D message communications are broadly divided into the two categories described below.
Of these two categories, the Inverter’s CompoBus/D Communications Card supports explicit mes­sages.

•Explicit Messages
Explicit messages are defined by DeviceNet. The class, instance, and attribute are specified for
executing message communications. The messages are the same for all Inverter products, so mes­sages can be exchanged in the same way with masters made by other manufacturers.

•FINS Messages
Messages can be exchanged using FINS commands between CompoBus/D nodes (Masters and
Slaves) that support FINS messages. (FINS commands are actually sent and received using Device­Net explicit messages.)

5-8

CompoBus/D Communications Card Operations Chapter 5

Note Message communications are supported by CV-series and C200HX/HG/HE PCs, but not by

C200HS PCs.

H Overview of Explicit Messages

Explicit messages are sent and received as described below. Basically explicit message communica­tions are executed in 1-byte (8-bit) units.

Header Node address Service code Class Instance Attribute Data Footer

Item Content

Header The header indicates the beginning of an explicit message and that the frame is an

explicit message request/response. It is set automatically for CompoBus/D
(DeviceNet), so there is no particular need to be concerned with it.

Node address Request: Set the node address of the Slave/Master to be requested.

Response: The node address of the responding Slave/Master is set.

Service code Request: Set the code of the requested service (read/write, etc.).

Response: The MSB (most significant bit) of the requested service code is
changed to “1” and returned.

Class Function classification (major

classification)

Instance Instance classification (minor

classification)

Attribute Attribute (Set values are assigned

for each function.)

Data Request: Set the data to be written.

Response: Read-requested data or fault message are attached.

Footer This is the part that indicates the end of the explicit message and executes the

CRC check. It is set automatically for CompoBus/D (DeviceNet), so there is no
particular need to be concerned with it.

Indicates the classification of a function
defined by DeviceNet. To specify a function,
specify these three codes.

5-2-2 Sending and Receiving Messages with C200HX/HG/HE

PCs

H Using IOWR

With C200HX/HG/HE PCs, explicit messages are sent using IOWR. To send an explicit message, it is
necessary to place FINS command “2801” in front and to send the command to the Master Unit. The
Master Unit that receives the command converts the command data to an explicit message and trans­fers it to the destination node. (When sending an explicit message, it is not possible to directly specify
the destination node with IOWR.)

H Message Timing

The Message Communications Enabled Flag must be used as an execution condition for the Master
when IOWR is used. Be sure this flag is ON before executing IOWR. If IOWR is executed when this flag
is OFF, a Special I/O Unit error may be generated for the Master.

3. When IOWR is completed, the Equals Flag turns ON and the self-holding bit is cleared.

Note 1. If IOWR ends in an error, the Equals Flag will not turn ON, so the self-holding bit will remain

ON.

Note 2. The Equals Flag is also affected by the execution of other instructions, so be careful not to use

any other such instructions between IOWR and the Equals Flag.

CompoBus/D Communications Card Operations Chapter 5

H Timing of Message Response Reading

Responses are read when the Message Communications Enabled Flag turns ON in the next cycle. The
Message Communications Enabled Flag will turn OFF when a Master Unit is executing message com­munications. If the message response is faster than the PC ladder program cycle time, the Message
Communications Enabled Flag will remain ON and response processing will not be possible. Execute
the read response processing before IOWR, as shown in the following diagram, and produce a Mes­sage Communications Status Flag (d) using bit A.

CompoBus/D Communications Card Operations Chapter 5 5-2-3 SYSMAC CV-series Message Transmission

H Using CMND(194)

With CV-series PCs, CMND(194) is used to send explicit messages. To send an explicit message, it is
necessary to place FINS command “2801” in front and to send the command to the Master Unit. The
Master Unit that receives the command converts the command data to an explicit message and trans­fers it to the destination node. When sending an explicit message, it is not possible to directly specify the
destination node with CMND(194).

5-2-4 Overview of Messages and Responses

When message communications are used, the Inverter’s CompoBus/D Communications Card returns
responses as explained below.

Basically, CompoBus/D (DeviceNet) communications are executed in 1-byte (8-bit) units. In the case of
single-word data (16 bits), the rightmost bits (least significant) and the leftmost bits (most significant)
are reversed in order due to the following reasons:

•Data on communications line is transmitted in the order of rightmost bits and leftmost bits.

•Data that is internally processed by PC for issuing commands is transmitted in the order of leftmost bits

and rightmost bits.

Therefore, reverse the order for attributes where “Word” is written in the “Size” column in the tables on
subsequent pages and create attached data or read response data.

Note There is no need to take this into consideration for remote I/O because the rightmost bits and

leftmost bits are automatically reversed.

Error code

•Identify objects (identification information): Class 01 hex

•Message router objects: Class 02 hex

•DeviceNet objects: Class 03 hex

•Assembly objects: Class 04 hex

•DeviceNet connection objects: Class 05 hex

•Motor data objects: Class 28

•Control supervisor objects: Class 29 hex

•AC/DC drive objects: Class 2A hex

The three types of objects related to Inverters are the motor data, control supervisor, and AC/DC drive
objects. These are explained below and in subsequent sections. The other types of objects are used
less frequently, and covered in 8-2 Objects.

Motor data objects are data and functions related to motors connected to Inverters. The motors that can
be connected to Inverters are squirrel-cage inductive motors, so the “Motor Type” is always “7.” The
motor’s rated current and rated voltage can be set and read.

5-2-6 Control Supervisor Objects: Class 29 Hex

Control supervisor objects are objects that have Inverter control I/O-related functions. They are as­signed according to their particular control I/O functions, such as forward operation, reverse operation,
error detection, and so on. Be careful when setting up a remote I/O communications connection. These
functions are shared with similar functions used for remote I/O, so even if they have been set for mes­sage operations they may get rewritten for remote I/O.

Note 1. The Net Reference and Reference From Net functions are applicable for Inverter software

versions S1042 and later . Cannot be changed during running. Check the version with the In­verter monitor function U1–14. If the software version is S1040, set b1–01 to “3.”

Note 2. Under the DeviceNet protocol, the unit for the speed reference is always r/min. The number of

motor poles (2 to 32) must be set in parameter o1–03 (frequency reference setting and dis-
play units) when using DeviceNet (open network).

Note 3. Cannot be changed during running.

D Communications Data Setting Examples

Example 1: Finding the communications data for outputting a frequency of 60 Hz with the following
conditions set.

Number of poles (o1–03): 4
Speed scale (attribute 16): 0

•Converting frequency to rotational speed:
Frequency x 120 / number of poles = 60 x 120/4 = 1,800 r/min

•Converting rotational speed to minimum unit:
Rotational speed / unit = 1,800 / (1 r/min x 1/2

•Converting communications data to hexadecimal: 1,800 (dec) = 708 (hex)

Example 2: Finding the communications data for outputting a frequency of 60 Hz with the following
condition set.

Frequency setting (o1–03): 0 (Cannot be set with DeviceNet protocol.)

0

) = 1,800

•Converting frequency to minimum setting unit:
Frequency / minimum unit = 60 / 0.01 = 6,000

•Converting communications data to hexadecimal: 6,000 (dec) = 1,770 (hex)

5-22

CompoBus/D Communications Card Operations Chapter 5

Note With frequency, the speed scale has no effect.

Example 3: Finding the communications data for setting a one-minute acceleration time with the follow­ing condition set.

Time scale (attribute 1C): –3

•Matching the acceleration time unit: 1 minute = 60 seconds = 60,000 ms

•Converting acceleration time to minimum unit:

Acceleration time / unit = 60,000 / (1 ms x 1/2

•Converting communications data to hexadecimal: 7,500 (dec) = 1D4C (hex)

D Communications Data Reference Example

In this example, the hexadecimal value BB8 that has been read is converted to frequency with the fol­lowing conditions set.

Number of poles (o1–03): 4
Speed scale (attribute 16): 1

•Converting communications data to decimal: BB8 (hex) = 3,000 (dec)

•Converting from minimum unit to r/min:

Communications data x unit = 3,000 x (1 r/min x 1/2

CompoBus/D Communications Card Operations Chapter 5 5-3 Switching Remote I/O Operation

To use remote I/O operations other than the standard remote I/O operation it is necessary to switch the
remote I/O operation. There are two ways to switch:

•Use the Configurator to set the remote I/O instance IDs for parameter objects.

•Set the remote I/O instance IDs for connection objects.

When an OMRON Master Unit is used, however, only the method utilizing the Configurator can be used
to switch remote I/O operations.

Note OMRON Master Units assume that communications will use remote I/O, so remote I/O commu-

nications are executed when the power is turned ON. Remote I/O operations cannot be switched
during operation under DeviceNet protocol. If remote I/O operations need to be switched, it must
be done by using the Configurator with the Master Unit’s power supply turned OFF.

H Switching via Parameter Objects (Using the Configurator)

To switch remote I/O operations using parameter objects, the appropriate instance IDs must be set for
the following parameter objects.

•Switching remote I/O inputs (3G3FV to SYSMAC PC):
Class 100 dec (64 hex), Instance 01 dec (01 hex), Attribute 202 dec (CA hex)

•Switching remote I/O outputs (SYSMAC PC to 3G3FV)
Class 100 dec (64 hex), Instance 01 dec (01 hex), Attribute 203 dec (CB hex)

The instances to be set are shown in the following table.

Remote I/O type

Inputs (3G3FV to PC) Outputs (PC to 3G3FV)

Basic remote I/O 70 Dec (46 hex) 20 Dec (14 hex)
Standard remote I/O 71 Dec (47 hex) 21 Dec (15 hex)
Special remote I/O 150 Dec (96 hex) 100 Dec (64 hex)

The procedure for switching remote I/O operations by means of object parameters is as follows:

1. Connect the 3G3FV Inverter and a Configurator to the CompoBus/D communications network. At
least a 3G3FV CompoBus/D Communications Card and a Configurator must be connected.

2. Set up the explicit message connection with no remote communications.
S Turn ON the power to the Configurator and the 3G3FV CompoBus/D Communications Card and

press the Configurator’s online button. Do not turn ON the power to the Master Unit at this time.
This will put the system into online status.

S Click the Device List button at the upper left corner of the Configurator screen. With this, the explic-

it message connection will be set up.

Instance ID

3. Connect the remote I/O to be used for the parameter objects.
S Select Tool (T) and then Device Parameter Setting (P) from the Configurator tool bar to display t h e

parameter setting tool.

S Set the node address, and then set the remote I/O instance IDs for the parameter objects de-

scribed above (attributes CA and CB hex of class 64 hex, instance 01 hex).

4. Cut off the Configurator and explicit message connection by turning OFF the power to the Inverter.

5-24

CompoBus/D Communications Card Operations Chapter 5

5. Set up the Master Unit and 3G3FV Inverter connection by turning ON their power. The remote I/O
connection will then start up with the specified remote I/O operation.
When creating scan lists, set the scan list to disable mode once and then create scan lists or change
the settings as follows for the Inverter I/O allocation byte number from the Configurator.

S Basic/Standard remote I/O: 4 bytes (both for OUT and IN)
S Special remote I/O: 4 bytes (both for OUT and IN)

H Switching via Connection Objects

This method is defined by OVDA AC/DC drive objects.

Connection Objects for Switching Remote I/O Operations

To switch remote I/O operations by this method, the appropriate instance IDs must be set for the follow­ing connection objects.

•Switching remote I/O inputs (3G3FV to SYSMAC PC):
Produced connection path (Class 05 hex, Instance 02 hex, Attribute 14 hex)

•Switching remote I/O outputs (SYSMAC PC to 3G3FV)
Consumed connection path (Class 05 hex, Instance 02 hex, Attribute 16 hex)

Remote I/O Instance ID

The instances to be set are shown in the following table.

Remote I/O type

Inputs (3G3FV to PC) Outputs (PC to 3G3FV)

Basic remote I/O 70 Dec (46 hex) 20 Dec (14 hex)
Standard remote I/O 71 Dec (47 hex) 21 Dec (15 hex)
Special remote I/O 150 Dec (96 hex) 100 Dec (64 hex)

Instance ID

Restrictions on Switching Remote I/O

To switch remote I/O operations, maintain either of the following conditions and send an explicit mes­sage.

•Remote I/O communications stopped after the remote I/O connection and explicit message connec­tion have been established.

•Remote I/O connection allocated after explicit message connection has been established.

Note The Configurator and OMRON Master Unit cannot create these conditions, so they cannot set

connection objects.

Data Setting Example

The set data must be converted to signal segments as defined by DeviceNet and then transferred. For
example, when remote I/O inputs are converted to special remote I/O inputs (instance ID: 96 hex), the
set data is as follows:

777000

011000100011100100110110

=62 39 36 Hex

“9” in ASCII code “6” in ASCII code

CompoBus/D Communications Card Operations Chapter 5 5-4 Special Remote I/O Operation

There are three kinds of CompoBus/D remote I/O operation: Basic remote I/O, standard remote I/O (the
default setting), and special remote I/O. This section explains special remote I/O.

Special remote I/O operation enables using all the functions of 3G3FV -series Inverters, and setting and
reading all parameters. These operations have been developed independently, and are not part of the
DeviceNet standard.

5-4-1 Overview of Special Remote I/O

Special remote I/O operations utilize CompoBus/D (DeviceNet) remote I/O, and can directly write to
and read from internal Inverter registers. Basically, the register numbers for the various functions shown
on this and subsequent pages are specified for writing or reading. Once data has been written, it is re­tained until it is changed by the next write operation.

Note 1. Special remote I/O outputs and inputs are paired. When using special remote I/O, be sure to

set them together.

Note 2. Special remote I/O objects do not conform to the AC/DC drive profile, but are specially set for

this product.

Note 3. The 16-bit data (register number and register data) is set in two words for each setting.

H Function Codes

The special remote I/O function codes are shown in the following table. Note that they are different from
the explicit message service codes.

Function code (hex) Content

10 Data writing
03 Data reading
00 No execution (data wrapping only; no internal

processing takes place.)

5-27

CompoBus/D Communications Card Operations Chapter 5

H Setting Data for Operations and Parameter Constants

Read data and write data to be set for operations and parameters are calculated as shown below and
then transmitted in hexadecimal.

•Convert to hexadecimal values with the operation/parameter minimum setting value as 1.

•Negative numbers are expressed as two’s complements.

•If the original data is already displayed in hexadecimal, it is transmitted as is.

Example 1

In this example, the frequency reference is 60 Hz, and the minimum setting unit is 0.01 Hz.
60/0.01 = 6000 → 1770 hex

Example 2

In this example, –50% (minimum setting unit: 0.1%) is set for the frequency reference (voltage) terminal
13 input bias.
50/0.1 = 500 → 01F4 hex

Bit reversal

+1

= FE0C hex

Example 3

In this example, “1F (hex)” is set for multi-function inputs.
“1F” is transmitted.

H Enabling Parameter Setting Data by Enter Command

When setting (writing) data in parameter constants, be sure to send an enter command. After receiving
the enter command, the Inverter will enable the data newly set in the parameter constants as operation
data.

When setting (writing) data in more than one parameter , send an enter command once after completing
all the settings. All the parameters newly set before the enter command is sent will be enabled.

Data type Transmission Inverter operation Remarks

Send data: 0000 hex

When receiving an enter
command, a series of
parameter setting data
will be stored in
EEPROM and enabled
as operation data.

When receiving an enter
command, a series of
parameter setting data
will be enabled without
storing them in
EEPROM.

All the set data will be
cleared to the initial data
when the power is turned
OFF.

Applicable to all the
Inverter software.

Applicable to Inverters
with software version of
S1042 or later.

5-28

CompoBus/D Communications Card Operations Chapter 5

Note 1. Unless an enter command is transmitted, data will not be enabled and the Inverter may not

start.

Note 2. The enter command requires a parameter constant (Register No. 0100 or higher). Since the

run command or frequency reference (Register No. 0000 to 000F) is stored only in the RAM
area, set data will be enabled without an enter command.

H Special Remote I/O Responses

When data is written and read using special remote I/O, the responses shown in the following table are
returned. Check that the input data and output data match when handling communications.

Error code Content

--- Normal completion response
The function code and register number at the time of transmission are placed at
the beginning, and returned with the data amount (when data is written) or the
read data (when data is read) attached.

01 Function code error

An unsupported function code was received.

02 Register number error

An unregistered register number was received.

21 Data setting error

An upper or lower limit was exceeded, or a constant restriction was violated. (See
note 2.)

22 Writing mode error

Either writing was executed during operation or during a CPU error, during UV, or
writing was attempted to a read-only register.

24 Busy

Writing was attempted during constant processing.

Note 1. When a communications error occurs, the function code MSB will be returned as “1.”
Note 2. A “constant restriction” is a restriction on OPE error detection.

5-4-2 Special Remote I/O Communications Timing

With special remote I/O communications, it is possible to use all of the SYSDRIVE 3G3FV functions,
such as frequency setting, control input setting, error monitoring, output frequency monitoring, and so
on. These functions are utilized by setting the register numbers and connecting to the various 3G3FV
functions. To use these functions properly, be sure to use the following method to handle the data and
provide a program for switching the communications processing.

H Matching Function Codes and Register Numbers

•In the remote I/O outputs (SYSMAC PC to 3G3FV), set the function code, register number, and set
data for the function to be executed.

•Compare (CMP) the function codes and register numbers of the set remote I/O outputs and the remote
I/O inputs (3G3FV to SYSMAC PC). If they agree, proceed to the next process.

Note If data is repeatedly written to the same register number, it cannot be handled. Be sure to keep

performing processes with different function codes or register numbers. If it is necessary to write
repeatedly to the same register number, then alternately write to and read from that register.
(Handling data is made possible by changing function codes.)

5-4-3 Inputting Control/Frequency

The Inverter’s various control inputs are allocated to the registers shown in the following table. For ex-
ample, to set the frequency reference and begin operation, first set the reference value to the frequency
reference register “0001,” and then write the run command to the Inverter’s run command register
“0000.”

Note 1. Set values are retained until changed by the next writing operation.
Note 2. The following registers are in RAM, so they are all cleared to zero when the Inverter’s power

supply is turned OFF.
