-PL2 Interface Option (Preliminary)

Communications:
The -PL2 Option uses the programming port protocol for communicating to

the Allen Bradley PLC-2. The T-60 Series can use the programming port on
the PLC-2 CPU or the programming port on the 1771-KA2 Interface Module.
The PLC-2 communication parameters are not configurable, so issuing the

CALL PLCINIT command will configure COM1 on the T-60 Series device to
the proper settings for the PLC-2.

The Data that cannot be accessed in the EMERSON EMC implementation of
the PLC-2 protocol as noted in the PLC-2 programming manual (Page C-3 -

Data Table Organization) are: Processor Work Areas No. 1 and No. 2, the

Reserved Area, the Expanded Data Table and/or User Program Area, and the
User Program Area. All other areas are accessible via the CALL PLCREAD
and CALL PLCWRITE commands.

Connections:
The -PL2 Option comes with the proper cable to interface to a PLC-2 directly

through the programming port, or to the programming port of the 1771-KA2.
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 Allen
Bradley PLC-2 or 1771-KA2 implementation of those commands.
