Introduction
Section 1-1
Connection can also be made from the COM port of the computer to the serial
communications port of a CS/CJ-series CPU Unit (or the Serial Communica-
tions Board/Unit) via Toolbus or Host Link. In this case, a CS/CJ-series
DeviceNet Unit (CS1W-DRM21 or CJ1W-DRM21) is necessary for connection
to the DeviceNet network.
Similarly, connection can be made from the Ethernet port of the computer via
a CS/CJ-series Ethernet Unit. In this case also, a CS/CJ-series DeviceNet
Unit (CS1W-DRM21 or CJ1W-DRM21) is necessary for connection to the
DeviceNet network.
Device Settings
The following parameter settings are for other manufacturers’ slaves as well
as OMRON’s master and slave devices.
A comment can be added to the I/O data of each device.
Note
1.
The same function can be achieved with the master functions enable/dis-
able setting.
2.
When not registered in the scan list, explicit message communications are
possible without remote I/O communications.
Device Monitoring
The status, error log, etc., of a device can be monitored, provided that the
device supports the monitor function. The monitor function is supported by
OMRON’s Master Units and some Special Slaves.

Description
CS1W-DRM21
C200HW-DRM21-V1
and
CVM1-DRM21-V1
Master functions enable/dis-
able
Enables or disables the master functions for
remote I/O communications.
Yes
No
I/O allocations
Slaves are allocated to the master in the desired
areas and order.
If the I/O allocations are simple, the Parameter
Wizard can be used to allocate I/O very easily.
I/O allocations are possible as well by just drag-
ging and dropping the slave to the allocation
area.
Yes
Yes
Communication cycle time
Sets the communication cycle time.
(The interval for I/O communications with
slaves.)
Yes
Yes
Connection setting
During remote I/O communications, the user can
make connection settings for up to two connec-
tions per slave. Automatic connection settings
can be selected as well.
Yes
No
Device data check
Determines whether slave device data items
(i.e., the vendor, device type, and product code)
are checked during remote I/O communications.
Yes
No
Slave functions enable/dis-
able
Enables or disables the slave functions for
remote I/O communications.
Yes
No
Slave functions I/O allocation I/O allocations can be made for slaves of the
CS1-series DeviceNet Unit. (I/O can be
allocated freely.)
Yes
No
Remote I/O
communications startup
Determines whether or not to start remote I/O
communications when the master is started.
(See note 1.)
Yes
Explicit message communi-
cations set/reset
Setting or resetting the function to enable explicit
message communications without remote I/O
communications.
(See note 2.)
Yes
