Conformance to EC Directives 6
6 Conformance to EC Directives
6-1 Applicable Directives
• EMC Directives
6-2 Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or
machines. The actual products have been checked for conformity to EMC
standards. (See the following note.) Whether the products conform to the
standards in the system used by the customer, however, must be checked by
the customer.
EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel in which the OMRON devices are installed.
The customer must, therefore, perform final checks to confirm that devices
and the overall machine conform to EMC standards.
Note Applicable EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic
Interference standards in the EMC (Electromagnetic Compatibility) standards
are as follows:
Unit EMS EMI
CS1W-DRM21 EN50082-2 EN50081-2
CJ1W-DRM21 EN61000-6-2
6-3 Conformance to EC Directives
DeviceNet products that meet EC directives must be installed as follows:
1,2,3... 1. DeviceNet Units are designed for installation inside control panels. All De-
viceNet Units must be installed within control panels.
2. Used reinforced insulation or double insulation for the DC power supplies
used for the communications power supply, internal circuit power supply,
and the I/O power supplies.
3. DeviceNet products that meet EC directives also meet the common emission standard (EN50081-2). When DeviceNet products are built into equipment, however, the measure necessary to ensure that the standard is met
will vary with the overall configuration of the control panel, the other devices connected to the control panel, and other conditions. You must therefore confirm that EC directives are met for the overall machine or device,
particularly for the radiated emission requirement (10 m).
The following examples show means of reducing noise.
1,2,3.... 1. Noise from the communications cable can be reduced by installing a ferrite
core on the communications cable within 10 cm of the DeviceNet Unit.

1-1 Overview of DeviceNet
DeviceNet is a multi-bit, multi-vendor network that combines controls and data
on a machine/line-control level and that conforms to DeviceNet open field network specifications.
Three types of communications are supported: 1) Remote I/O master communications that automatically transfer I/O between slaves and the CPU Unit to
which a DeviceNet Unit is mounted without any special programming in the
CPU Unit, 2) Remote I/O slave communications that automatically transfer I/O
between the Master and the CPU Unit to which a DeviceNet Unit is mounted,
and 3) Message communications that read/write messages, control operation,
or perform other functions for other CPU Units to which a DeviceNet Unit is
mounted and slaves. Message communications are achieved by executing
specific instructions (SEND (192), RECV (193), and CMND (194)) from the
program in the CPU Unit to which the DeviceNet Unit is mounted.

The following functions are supported with a CS/CJ-series DeviceNet Unit.
a) I/O area words can be flexibly allocated for remote I/O Master and
Slave communications. Three types of fixed allocations as well as
user-set allocations through allocated DM Area words are possible.
b) More than one DeviceNet Unit can be mounted under a single PC.
c) More than one DeviceNet Unit can be connected in a single network.
With the Configurator, remote I/O can be allocated in any order, i.e.,
not necessarily in the other of node addresses.
Note The Configurator that is connected through a dedicated Board or
Card uses one node in the DeviceNet network. It does not use a
node if it is connected by a serial line.
2. A CS/CJ-series DeviceNet Unit can function as either a master or slave in
remote I/O communications. Both can be used simultaneously.
3. With a CS/CJ-series DeviceNet Unit, the DeviceNet network can be treated exactly like a Controller Link, Ethernet, or other network for message
communications or remote programming and monitoring by a CX-Programmer.

1-2 DeviceNet Unit Features
The following are features of the CS-series and CJ-series DeviceNet Units
(CS1W-DRM21 and CJ1W-DRM21).
Multi-vendor Network Devices made by other companies (masters or slaves) can be connected to
DeviceNet because it conforms to open field network specifications. By using
a combination of valves, sensors, and other DeviceNet products, the network
can be adapted to various field-level applications.
Simultaneous Remote I/O
Communications and
Messaging Services
Note Refer to SECTION 4 Remote I/O Master Communications for details on
Remote I/O communications that constantly transfer I/O between a DeviceNet
Unit and slaves as well as message communications where the DeviceNet
Unit sends and receives data as needed can both be executed simultaneously. When a DeviceNet network is constructed, this feature ensures the
network will be able to handle applications that require the free flow back and
forth of bit data and message data. FINS commands can be executed along
with DeviceNet explicit messages in message communications.

User-set allocations
without the Configurator
With CS/CJ-series DeviceNet Units, remote I/O communications can be allocated in any area without the Configurator simply by using DM Area settings.
If the Configurator is used, it allows you to change the node address order for
more flexible I/O allocations. This feature ensures the proper I/O allocations
for any application and it makes effective use of PC memory by simplifying
programming.
Note Refer to 4-4 User-set Allocations for details.
Slave Functions CS/CJ-series DeviceNet Units can be used as both masters and slaves, and
master and slave communications can be executed either separately or simul-

Normal multi-drop, T-branch multi-drop (with up to three branches), and daisychain line connections are available. These methods can be combined to construct a flexible system that suits the floor layout.
A network can connect up to 63 Slaves and can handle remote I/O communications of up to 2,000 byes (16,000 points without the Configurator) per
DeviceNet Unit. A maximum network length of 500 m is possible with a baud
rate of125 Kbps using thick cable.
High-speed communications are possible at up to 500 Kbps for a trunk line
length of 100 m.
The communications cycle time can be set even without the Configurator so
slaves with slow response times can be used.

1-6-4 Procedures Prior to Starting Communications
Using the Master Function
To use the master function, the Master Enable Switch (word n, bit 06) must be
turned ON from a Programming Device. Enable master communications
through CS1W-DRM21 properties if you are using a Configurator.
Note 1. Make sure the scan list is enabled when using the master function. This
will allow you to check whether slaves are online or not from the CPU Unit
so that you will be able to determine whether or not the DeviceNet is communicating properly.
2. Remote I/O communications with a specified slave can be turned OFF
(disconnected) by turning ON (1) the corresponding Disconnect/Connect
Switch (words n+6 to n+9) when a slave is replaced or is registered in the
scan list prior to being connected. These switches are cleared when the
power supply is turned OFF, however, so a bit must be turned back ON (1)
from the ladder program when the power turns ON for it to be valid again.
Fixed Allocations
Use the following procedure to use fixed allocations. Refer to 4-3 Fixed Allocations for details on fixed allocations.
1,2,3... 1. Turn ON the communications, slave, and PC power supplies.
Note Turn ON the communications power supply before turning ON the
slave power supplies or the slaves may not go online.
2. Switch the CPU Unit to PROGRAM mode.
3. Check Unit Status 2 (word n+11, bit 03) from a Programming Device connected to the CPU Unit to see if the master function is ON (enabled). If it
is enabled, skip step 4 below and proceed to step 5.
4. If the master function is OFF (disabled), turn ON the Master Enable Switch
(word n, bit 06) from a Programming Device connected to the CPU Unit.
Note Execute this only when master communications are turned OFF. (If
the Master Enable Switch is turned ON when master communications are ON, a Unit error will occur and a C2 error will be displayed
on the 7-segment display on the front panel.)
5. Turn ON the Master Fixed Allocation Area Setting 1 to 3 Switches (word n,
bits 8 to 10). Master remote I/O communications will begin with the scan
list disabled.
6. Turn ON the Scan List Enable Switch (word n, bit 00). Master remote I/O
communications will begin with the scan list enabled.
7. Switch the CPU Unit to RUN mode.
User-set Allocations Using Allocated DM Area Words
Use the following procedure to set allocations using the words allocated to the
Unit in the DM Area. Refer to 4-4 User-set Allocations for details on user-set
allocations.
38
1,2,3... 1. Turn ON the communications, slave, and PC power supplies.
Note Turn ON the communications power supply before turning ON the
slave power supplies or the slaves may not go online.
2. Switch the CPU Unit to PROGRAM mode.
Basic Operating Procedures Section 1-6
3. Check Unit Status 2 (word n+11, bit 03) from a Programming Device connected to the CPU Unit to see if the master function is ON (enabled). If it
is enabled, skip step 4 below and proceed to step 5.
4. If the master function is OFF (disabled), turn ON the Master Enable Switch
(word n, bit 06) from a Programming Device connected to the CPU Unit.
Note Execute this only when master communications are turned OFF. (If
the Master Enable Switch is turned ON when master communications are enabled, a Unit error will occur and a C2 error will be displayed on the 7-segment display on the front panel.)
5. Input data in advance into the Master User Allocation Setup Table (words
m+1 to m+6) and the Allocation Size Setup Table (specify the position in
words m+5 and m+6)
6. Turn ON the Master User-set Allocation Switch (word n, bit 11). Master remote I/O communications will begin with the scan list enabled.
7. Switch the CPU Unit to RUN mode.
User-set Allocations Using the Configurator
Use the following procedure to set allocations using the Configurator. Refer to
DeviceNet Configurator Operation Manual for details on Configurator operating procedures
1,2,3... 1. Turn ON the communications, slave, and PC power supplies.
Note Turn ON the communications power supply before turning ON the
slave power supplies or the slaves may not go online.
2. Switch the CPU Unit to PROGRAM mode.
3. Create a network configuration file and device parameters file from the
Configurator. (Enable master communications in CS1W-DRM21 properties at this time.)
4. Download the above files to the devices on the network. Remote I/O communications will begin with the scan list enabled.
5. Switch the CPU Unit to RUN mode.
Using Slave Function
Fixed Allocations
1,2,3... 1. Switch the CPU Unit to PROGRAM mode.
To use the slave function, the Slave Enable Switch (word n+1, bit 06) must be
turned ON from a Programming Device. Enable slave communications
through CS1W-DRM21/CJ1W-DRM21 properties if you are using a Configurator.
With fixed allocations or allocations set in the allocated DM Area words, slave
communications must be disabled prior to area allocation and must be
enabled following area allocation. The order of the procedure is thus Slave
Stop Switch (if slave communications are enabled), area allocation, and Slave
Enable Switch.
Note Slave communications must be disabled prior to area allocation when using
fixed allocations or allocations set in the allocated DM Area words, and the
settings must be read to the Unit when slave communications are enabled.
Allocations will not be valid if slave communications are enabled during area
allocation.
Use the following procedure to use fixed allocations. Refer to 5-2 Fixed Alloca-
tions for details on fixed allocations.
39
Basic Operating Procedures Section 1-6
2. Check Unit Status 2 (word n+11, bit 07) from a Programming Device connected to the CPU Unit to see if the slave function is OFF (disabled). If it is
disabled, skip step 3 below and proceed to step 4.
3. If slave communications are enabled, turn ON the Slave Stop Switch (word
n+1, bit 07).
4. Turn ON the Slave Fixed Allocation Area Settings 1 to 3 Switches (word
n+1, bits 8 to 10).
5. Turn ON the Slave Enable Switch (word n+1, bit 06) from a Programming
Device connected to the CPU Unit.
Note Execute this only when slave communications are turned OFF. (If the
Slave Enable Switch is turned ON when slave communications are
enabled, a Unit error will occur and a C2 error will be displayed on
the 7-segment display on the front panel.)
6. Switch the CPU Unit to RUN mode. Slave remote I/O communications will
begin.

In addition to the MS and NS indicators, DeviceNet Units have a 2-digit, 7segment display that normally indicates the master node address. When an
error occurs, the display will alternate between the error code and the node
address of the faulty slave.
There are dot indicators at the lower-right corner of each digit. The left dot
indicator shows whether or not the master is operating and whether the scan
list is enabled or disabled. The right dot indicator shows whether or not the
slave is operating.
Normal: Master's node address
Error: Error code and faulty node address
Indicates whether the master is operating or stopped and
whether the scan list is enabled or disabled.

another CPU Bus Unit connected to the same PC.
3. Use a small flat-blade screwdriver to turn the rotary switches; be careful
not to damage the switch.
4. Always turn OFF the PC before changing the unit number setting.
5. If the unit number is the same as one set on another CPU Bus Unit connected to the same PC, a duplicate number error will occur in the PC and
it won’t be possible to start up the DeviceNet network.
Setting method: Two-digit decimal

Nomenclature and Functions Section 2-1
Note 1. The node address is set to 63 at the factory.
2. Any node address from 0 through 63 can be set as long as it hasn’t been
set on another slave node.
3. If the node address is the same as one set on another node, a node address duplication error will occur and it won’t be possible to start up network communications.
4. Node address 0 cannot be used for FINS message communication. Use a
node address other than 0 for FINS message communication.
DIP Switch The DIP switch on the front of the DeviceNet Unit is used to set the baud rate,
whether communications will be continued or stopped when a communications error occurs, and whether to hold or clear the remote outputs when a
communications error occurs in the slave function.

Continue/Stop Remote I/O Communications
When the DeviceNet Unit is used as a master, pin 3 is used to set whether or
not communications will stop after a communications error.
Pin 3 Function
OFF Continue communications.
ON Stop communications.
If pin 3 is ON, remote I/O communications will be stopped if one of the following errors occurs.
Remote I/O Communications Error Flag (n+12, bit 02 is ON)
Send Timeout Flag (n+10, bit 08 is ON)
Network Power Error Flag (n+10, bit 07 is ON)
Remote I/O communications will remain stopped even if the error is cleared.
(Message communications and slave functions will continue.) To resume communications, turn ON the Remote I/O Communications Start Bit (word n, bit
02) of Software Switches 1. Refer to 3-2 Allocated CIO Area Words for details.
Note The 7-segment display will show “A0” when remote I/O communications stop.
Refer to SECTION 9 Troubleshooting and Maintenance.
If pin 3 is OFF, remote I/O communications will stop if a send timeout or network power error occurs, but will restart automatically when the cause of the
error is cleared.
Communications
Connectors
Hold/Clear Remote Outputs
When the DeviceNet Unit is used as a slave, pin 4 is used to set whether to
hold or clear remote outputs when a communications error occurs.
Note If the DeviceNet Unit is used as a slave, the 7-segment display will show “L9”
when remote I/O communications stop. Refer to SECTION 9 Troubleshooting
and Maintenance.
Color stickers that match communications cable colors are attached to the
communications connectors. Match the colors when connecting communications cables to the connectors. These colors are given in the following table

All switches execute some function when the user turns them ON. They turn
OFF automatically after the function has been executed. Once a function is
set by turning a switch ON (except for the switches listed below), it is saved
regardless of whether the power is turned OFF and ON again.

Remote I/O Communications Start Switch (bit 02, 03)
• Remote I/O Communications Stop Switch (bit 04)
Note No functions other than master and slave communications are disabled by
stopping master or slave communications.
If multiple bits are turned ON simultaneously, the requests will generate errors
but they will not alter Unit operation. The corresponding error bits in the following words will turn ON if a request made by a software switch ends in an error.

More than one of these switches may be turned ON at the same time. The
switches will return to OFF starting at the switches for the slaves to which
COS data has been sent.
If a send error occurs, the corresponding bit will turn ON in Slave Detailed
Status.
3-2-4 Disconnect/Connect Switches (Words n+6 to n+9)
One Disconnect/Connect Switch is allocated to each slave node address. If
the switch for a slave is turned ON, then remote I/O communications to that
slave will be temporarily stopped (i.e., it is disconnected from the network). A
communications error will occur at the end for any slave has been disconnected if the corresponding switch is turned ON during communications.
These switches are used primarily to replace slaves or to reserve a place for a
slave that will be added (when a Unit is registered in the scan list but not yet
connected). A communications error and verification error for the slave that
has been disconnected will not be generated at the master as long as the corresponding switch is ON.
Note These switches do not add or remove slaves from the registered scan list.

Remote I/O communications will restart if a user turns OFF a bit that is ON.
More than one of these switches may be turned ON at the same time. If the
switch for a slave that is not using remote I/O communications is turned ON, it
will be ignored.
A Unit that has been disconnected can still perform message communications.
Turning ON this bit does not effect the communications cycle time (except that
it increases blank time in the communications cycle).
Note All Disconnect/Connect Switches are cleared and return to OFF
when the power is turned OFF. If required, write the ladder program
to turn them back ON when the power is turned ON.

If this bit is set to 0, the optimum time calculated by the Unit will be used. If a value
higher than 500 ms is set, then the Unit will
operate at 500 ms.
If the setting cannot be correctly made for
some reason, the Scan List Register/Clear
Failed Flag (word n+12, bit 11) in Master Status 1 and the Temporary Setting Switch for
Communications Cycle Time (word n, bit 12)

Note If the setting is smaller than the optimum communications cycle time calcu-
lated by the Unit and stored internally in the Unit, then the value calculated by
the Unit will be used.
