MOD Interface Option
Communications:
The -MOD Option communicates via the Modbus protocol. It was developed
to allow the T-60 Series to communicate easily to the Modicon PLC’s that use
the Modbus protocols (Micro 84, 484, 584, 184/384, 884, 984/381, etc.) It also
works well with communication modules available for other PLC’s like GE
Fanuc’s Serial Communications Module (Cat.# IC693CMM311 used in RTU
Mode). When used with a Modicon PLC, the communications occurs via the
programming port. The T-60 Series does auto-detect for the serial
communications parameters, therefore no special procedures are necessary
for configuring the serial port on the PLC. The CALL PLCINIT command
takes care of configuring COM1 on the T-60 Series device and initializing the
communications with the PLC.
Connections:
The -MOD Option comes with the proper cable to interface to the Modicon
PLC. For those who need to change the length of the cable, the proper
connections are shown below:
Command Variations:
There are no variations between the descriptions of CALL PLCINIT, CALL
PLCREAD, and CALL PLCWRITE in the previous section and the Modbus
implementation of those commands.
