set to whichever Node Number
will be mapped to the RMC's IP
address. 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.
Network Send: SEND(090) for CS1, SEND(192) for CV
This instruction is used to write data from the PLC's registers to the RMC's registers. It has the
following format:
SEND should be energized for only one scan to start the communication. After that, the
Communications Port Enabled Flag (A202.00 to A202.07 on the CS1 family and A502.00 to
A502.07 on the CV family) should be used to determine when the operation is complete, as
described in the Omron documentation. Each parameter is described below:
S First Source Word in Local Node. Give the starting address in the PLC of the data to write to the
RMC. This is typically a DM address.
D First Destination Word in Remote Node. Give the starting address in the RMC of the place to
write the data. This must be a DM address (Dnnnnn). None of the RMC's EM banks can be
written to. Refer to the RMC Register Map (Omron FINS) topic for exact addresses.
C First Control Word. This instruction uses a block of five control words. These words are used to
control the network communication itself. These five words are defined as follows:
Word MSB (Bits 8-15) LSB (Bits 0-7)
C Number of words to write (1 to 512).
The PLC supports writes up to 990 words, but the RMC is limited to 512
words.
C+1 Always 00 for RMCs. Remote Network Address.
For RMCs, this value should be
set to the address of the RMC's
Ethernet network.
