Delta RMC101 - Manual (Page 383)

Ethernet 5.2
Communications 5-133
C+2 Remote Node Number.
For RMCs, this value should be
set to whichever Node Number
will be mapped to the RMC's IP
address.
Remote Unit Number.
For RMCs, this value should be
0.
C+3 Port Number: 00 to 07.
The Port Number is used to
allow simultaneous
communications in the PLC.
Use a different number for each
communication that may be
requested simultaneously.
No. of Retries: 00 to 0F (0 to
15).
For RMC communications, this
value should be between 2 and
5.
C+4 Timeout: 0001 to FFFF (0.1 to 6553.5 seconds).
The default setting of 0000 sets a monitoring time of 2 seconds. For
RMC communications, this value should be set to 0001 or 0002 for 0.1
or 0.2 second timeouts.
CS1 Example
The user has an Omron CS1 PLC with a CS1W-ETN01 Ethernet Unit and an RMC-ENET. The
Omron PLC has just one network, which is the Ethernet network accessible through an ETN01
Ethernet Unit. This network has Network Address 1. The ETN01 Ethernet Unit has Unit Number
0. The Omron PLC has IP address 192.168.0.2, and the RMC has IP address 192.168.0.5. The
Omron ETN01 is set up to use Automatic Address Generation, so the RMC has Node Number 5,
and the ETN01 has node number 2.
The following diagram demonstrates the configuration:
The Omron PLC must have one entry in its Local Network Table. This entry assigns Network
Address 1 (the Ethernet network) to Unit Number 0 (the ETN01 Ethernet Unit).
The user wishes to continuously read the 80 status words starting at address D0 in the RMC and
store them at D0 in the PLC. The user also wishes to write 48 words from D100-D147 to the
RMC's command registers D80-D127 whenever the 1200.00 coil is set. The following ladder logic
does this:
