MULTIPLE I/O TERMINAL Section 1-1

1-1-3 Features

Simple Connections The Communications Unit and the I/O Units ar e separate, and the Communi-

cations Unit and the I/O Units ar e connec ted by an I/O U nit in terface. I/O can
be expanded simply by connecting additional I/O Units to the I/O Unit inter­face.

Automatic Recognition of
I/O Units

When the power to the Communications Uni t is tur ne d ON, the models of the
I/O Units on the I/O Unit interface are aut oma tic ally re co gni zed, and t he num­ber of remote I/O communication s points with the DeviceNet Master Unit is
automatically determined. This enables I/O to be increased or decreased sim­ply by connecting or disconnecting I/O Units.

Status Notification Status information about the I/O Unit i nterface can be tran sm itt ed as inp uts to

the DeviceNet Master Unit (two words).

Many Types of I/O Unit The following I/O Units are available.

• 16- or 32-point Transistor Input Units (terminal block, connector, 25-pin D­sub connector, or high-density connector)

• 16- or 32- point Transist or Output Units (ter minal block, connector, 25-pin
D-sub connector, or high-density connector)

• 8-point/16-point Relay Output Unit (16-point Unit)

• 4- or 8-point Analog Input Unit (terminal block or connector)

• 4-point Analog Output Unit (terminal block or connector)

• 1-point Pulse Input Unit (high-speed counter)

• 4-point Temperature Input Unit

An I/O-intensive System
Can be Built at Low Cost

Compared with fixed I/O Terminals, a high cost-performance ratio can be
achieved if I/O Units are used.

Range Setting by
Configurator

The input and out put ranges for the Analog Input, Analog Output, an d Tem­perature Input Units can be set for each point using the Configurator (with ver­sion 1.11 or later). Usin g DIP switches, ranges can be set in 2- point units for
the Analog Input and Analog Output Units, and in 4-point units for the Temper­ature Input Unit.

I/O Interface Current
Consumption

Make sure that the power supply from t he Communications Unit to the I/O
Units is less than the total rated output curre nt (400 mA). The I/O inter face
current consumption for each I/O Unit is shown in the following table.

Calculation Example

When five GT1-ID32ML Input U nits and three GT1-OD16 Output Units are
used, the total current consumption is calculated as follows:

(GT1-ID32ML current consumption) x 5 Units
+ (GT1-OD16 current consumption) x 3 Units
= 55 mA x 5 + 35 mA x 3 = 380 mA

≤ 400 mA

I/O Unit Interface

Functions Section 1-2

Remote I/O communications with the DeviceNet Master Unit ar e carried out
by a MULTIPLE I/O TERMINAL base d on the registered co nfiguration. When
the power to the Communications Unit is turned ON, the bits allocated to the I/
O Units can be used to check the status (bits 0 to 7 of the first word) of the
Communications Unit.

Note 1. If the configuration of the I/O Units is to be changed, a number of prec au-

tions must be noted. For details, see 1-2-5 I/O Configuration Changes.

2. For details of data exchange timing, see 6-1-1 I/O Response Time.

Error Processing Even if an error occurs in the I/O Unit interface after initialization is completed,

DeviceNet communications will continue normally. Therefore, an error pro­cessing program section must be included in the CPU Unit to check the status
of the Communications Unit for errors that have occurred and to ide ntify the
error type and location.

1-2-3 Allocating I/O

This section explains how words for a MULTIPLE I/O TERMINAL are allo­cated in the output area and input area of the Master. For details of remote I/O
functions in the output area and input area of the Master such as word specifi­cation, fixed allocation, and us er-set al loca tion, r efer to the DeviceNet Opera-
tion Manual (W267).

Fixed Allocation The output area and inpu t area corresponding to the Communicatio ns Unit

node number for a MULTIPLE I/O TERMINAL are as shown in the following
diagram.

Output Area

The output area contains output bits in the order tha t I/O Units are co nnecte d
on the I/O Unit interface.

Input Area

The input area contains the Communications Unit status (two words), and
input bits in the order that I/O Units are connected on the I/O Unit interface.

The input and output bits for the I/O Unit interface are allocated in the
DeviceNet input and output are as in 16-poin t (one word) inc rements. With 8­point I/O Units, these bits are alloc ated using the r ightmost byte (bits 0 to 7) ,
and the leftmost byte (bits 8 to 15) will be 00 Hex.

Allocation Precautions Note the following precautions when starting the DeviceNet Network.

Limits on the Total Number of Input and Output Points for a Master Unit

A maximum of 1,024 input s and outpu ts can be c ontrolled by one Com muni­cations Unit (DRT1-COM). The number of I/O points for each node, however,
depends on the Master Unit. For example, with the CV-series Master Unit
(CVM1-DRM21-V1) or the C200HX/HG/HE and C200HS Master Unit
(C200HW-DRM21-V1), up to 512 inputs and up to 512 outputs can be used at
each node. Therefore, connect I/O Uni ts within a range that does not exceed
the number of I/O points for each Master Unit node. The following table shows
the I/O size of each Unit.

The GT1-ROP08 (Relay Output Unit with Power Relay) has 8 actual outputs
but, as a MULTIPL E I/O TERMINAL, the number of outputs allocated to the
Master Unit is 16.

Calculation Example

When one GT1-DA04MX Analog Output Unit and three GT1-AD08 Analog
Input Units are used, th e tot al number of inp ut p oin ts and outp ut points is cal­culated as follows:

Total Number of Input Points:

Communications Unit (Status) + Analog Input Units x 3
= 32 points + 128 points x 3 = 416 points

Total Number of Output Points:

Analog Output Units x 1
= 64 points

Abnormal I/O Unit Addresses and Registered I/O Unit Addresses

1-2-5 I/O Configuration Changes

The I/O Unit interface automatically recognizes the I/O Unit configuration each
time the Communications Unit is started up, and stores this as th e normal
configuration.

Note 1. If the I/O Unit configuration is c hanged wh ile the Communications Unit is

turned ON, a configuration error will occur. Do not change the I/O Unit con­figuration while power is being supplied to the Communications Unit.

2. If a configuration error occurs on the I/O Unit interface, I/O refreshing of all
I/O Units will stop. Even if a configuration err or occurs, communications
with the DeviceNet Network will continue, using the initial I/O Unit configu­ration. An error processing p ro gram se cti on must therefore be included in
the CPU Unit to regular ly check whether or not a configuratio n error has
occurred (status bit 1) and to process abnormal I/O Unit addresses.

If the I/O Unit configuration is changed, perform the following operations,
according to the DeviceNet area al location method. For details about I/O all o­cation, refer to DeviceNet Operation Manual (W267).

Default Allocations Because the allocation size of the Communications Unit changes together

with changes to the I /O Unit configuration, a verification er ror will occur on
DeviceNet if the scan list is enabled, as follows:

• Master Unit 7-segment display will show d6, Slave I/O size mismatch.

• Master status bits 14 and 7 will turn ON.

Perform the following operations, according to the s tatus of the input/output
areas.

Allocation Areas Do Not Overlap with Other Slaves

Remote I/O communication s will be performed unchanged with th e new con­figurat io n. Che ck the Ve rif ic at i o n Err or Bit and, if required, pe rform processing
to disable the allocated words in the CPU Unit. Also check the number of
points for the changed I/O Unit and its allocation area on the I/O Unit inter­face, and re-register the scan list (first set the Scan List Enable software
switch to OFF, and then set it to ON after checking the I/O size).

Allocation Areas Overlap with Other Slaves

In this case, I/O area duplication will also occur on the DeviceNet, as follows:

• Master Unit 7-segment display will show d0, I/O area duplication.

• Master status bits 14 and 4 will turn ON.

Check the Verification Error Bit, and perfor m processing to disable the allo­cated words in the CPU Unit. Also ch ang e the Slave node number so t hat th e
allocation area does n ot overlap with any other, and re-register the sca n list
(first set the Scan Lis t Enable software switch to OFF, and then set it to ON
after checking the I/O size).

Note If the scan list is disabled, there will be no changes made in the DeviceNet

Master Unit, even if the Communications Unit input/output sizes ch ange. Be
sure to use the Scan List Enable Mode for normal operations.

The bits corresponding
to I/O Unit with errors
are turned ON. Bits 8 to
15 correspond to
addresses 0 to 7.

0: No error, or not

User-set Allocations The sizes of the allocated areas for the Communications Unit will change with

changes to the I/O Unit config uration , caus ing a Verification Erro r to oc cur o n
DeviceNet if the scan list is enabled, as follows:

• Master Unit 7-segm ent display will show d6, a Slave I/O size mismatch.

• Master status bits 14 and 7 will turn ON.

Perform the following operations, according to the s tatus of the input/output
areas.

Allocation Areas Do Not Overlap with Other Slaves

Remote I/O communication s will be performed unchanged with th e new con­figuration data. Check the Verification Error Bit and, if r equired, perform pro­cessing to disable the allocated words in the CPU Unit. A lso, perform change
the allocations using the Configurator.

Allocation Areas Not Overlap with Other Slaves

In this case, I/O area duplication will also occur on the DeviceNet, as follows:

• Master Unit 7-segment display will show d0, I/O area duplication.

• Master status bits 14 and 4 will turn ON.

Check the Verification Error Bit, and perfor m processing to disable the allo­cated words in the CPU Unit. Also, perform change allocations using the Con­figurator.

2-2 Specific Example

1,2,3... 1. Determine the MULTIPLE I/O TERMINAL I/O specifications.

Each Communications Unit for the MUL TIPLE I/O TERMINAL can be con­nected to a combined total of 1 ,024 input and output points (64 words)
max. (This figure does not incl ude the 2 words of the inp ut area all ocate d
to the I/O Unit interface status.)
In this example, the following configuration will be used:

• Inputs : 16 points

• Outputs : 16 points

• Analog Input: 8 inputs (8 words)

• Analog Output: 4 outputs(4 words)

2. Select the I/O Units.

• DRT1-COM Communications Unit: 1 Unit

• GT1-ID16 Transistor Input Unit, 16 points with terminal block: 1 Unit

• GT1-OD16MX Transistor Output Unit, 16 points with connector:1 Unit

• GT1-AD08MX Analog Input Unit, 8 inputs: 1 Unit

• GT1-DA04MX Analog Output Unit: 4 outputs: 1 Unit

3. Check the specifications.

• Check tha t th e t otal num ber o f i np ut and ou tput points (words) is less
than 1,024 (64). In this example, the number of points is calculated as
follows:
Inputs (16 points) + Outputs (16 po ints) + Analog Input (8 words x 16
points) + Analog Output (4 words x 16 points)
= 224 points

Note There are DeviceNet Master Units that have restrictions on the num-

ber of input and output points per Slave Unit. Make sure that the
number of input and output points doe s not exceed the limit for the
Master Unit. (For example, the C200 HW-DRM21-V1 has an upper
limit of 512 for both input and output points.) The maximum number
of input and output points for the Master Unit, includ es the 2 words
allocated to the I/O Unit i nterface status. When calcula ting the total
number of input and output points, be sure to include this (32 points)
in the calculation.

• Check that the total I/O Unit interface current consumption is less than

0.4 A. In this example, the total is calculated as follows:
Transistor Input Unit (35 mA) + Transistor Output Unit (35 mA) + Ana­log Input Unit (50 mA) + Analog Output Unit (50mA)
=170 mA

3-1-2 Present Count Value Reading

If the following bits in the output area for the Counter Unit have been set to
ON, the set values or the present count value (coun t value) will always be
read to words m and m+1 in the input area.

To read set value 1: Output area word n+2, bit 04
To read set value 2: Output area word n+2, bit 05
To read count value: Output area word n+2, bit 06

The simplest example of a program to comme nce co unt operat ion and ob tain
the count value is given in the following. For details refer to 5-4 GT1-CT01
Counter Unit.

Note 1. To execute counting, it is necessa ry to set the co unt mode. If the count

mode is changed during count operation, however, the count value will be
cleared to 0.

2. Setting and reading will not be executed if a bit with a higher priority is ON.
As shown in the following example, therefore, it is recommended that word
n+2 be used with the MOV instruction.

3-1-3 Counter Setting and Execution

When the program is executed, the necessar y settings for the Counter Unit
will be made, and count operation will star t. Duri ng count operation, external
outputs 1 and 2 of the Counter Unit will automatically switch ON or OFF,
according to the count value.

Note It will be necessary to reset all the settings, including the set values,

present value and count mode, every time the Counter Unit is turned
ON.

When execution of count value reading is indicated
(execution conditions are ON), set the following condi-

tions:

• Word 53
Bit 03: Data code BCD
Bit 06: Count value reading
Bits 10, 11: Count mode phase difference ×1
The count value will subsequently be sent to words m
and m+1 (353, 354) of the Counter Unit automatically.

Examples of Counter Unit Operation Section 3-1

3-1-4 Count Restart Operation after Error Clearance

If power supply from the I/O Uni t interface to the Counter Unit is interru pted,
the Counter Unit will stop count operation . It will be nece ssary to res tart th e
count operation. When the C ounter Uni t is restarted, all sett ings, such as th e
setting values, the present value, and the count mode will be cleared. Th ese
settings must be reset. By adding the following program to the program
described in the pr evious section, 3-1-3 Counter Setting and Execution, the
settings will be res et automatic ally when the Counter Un it is resta rted, and it
will be possible to resume count operations. An example of the program used,
along with an explanation of that program appears below. For details about
the status area of the Master Unit, refer to DeviceNet Operation Manual
(W267).

If any of the following occur after the Counter Unit setting
and start-up have been completed (and 23204 is ON),
the Step Advance Bit 23300 turns ON in order to reset
the settings for the Counter Unit.

• The Communications Unit Bit (node number 01 =

10601) for the Master Unit normal Slave information
area is OFF (error).

• Bit 5 (10105) of the Master Status Area 1 is ON
(transmission error in the DeviceNet).

• The Counter Unit Bit (#0 = 35208) for the error I/O Unit
address in the I/O Unit Interface Status Area is ON
(error).

When the Step Advance Flag 23300 turns ON for reset­ting, if all of the following conditions are satisfied, the
Counter Unit will start up normally and communications
will be possible. Therefore, the Step Advance Flag 23200
will turn ON. The previously described setting and execu­tion program will be re-executed.

• Bit 15 (10115) of the Master Status Area is ON (Device
Net remote I/O communications are operating).

• Bit 15 (35115) of I/O Unit connection information in the
I/O Unit Interface Status Area is ON (I/O refresh in prog-

ress).
