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.
