Publication 1336 FORCE–5.13 –– September, 1998
When configured for RIO scanner communications, the PLC
Communications Adapter Board can:
•
Support 57.6K, 115K, or 230K baud communication rates at all
valid module groups.
•
Be configured as a 1/4, 1/2, 3/4, or full I/O rack.
•
Be configured to ignore PLC fault conditions and continue
operating.
•
Allow the 1336 FORCE to scan a logical rack of data from
multiple devices (such as Flex I/O, 1771–ASB, or a 1336 FORCE
as an adapter)
The terminating resistors (R1 and R2 in the figure below) depend on
the baud rate:
If you are using this baud rate:

You can connect up to four devices to a channel of a PLC
Communications Adapter Board that is operating in RIO scanner
mode. These devices do not have to be other 1336 FORCE drives
with PLC Communications Adapter Boards attached. This wiring
configuration shows three PLC Communications Adapter Boards
attached to the PLC Communications Adapter Board in RIO scanner
mode to show the wiring connections you would need.
