Communication Rate
You set these switches (S2-3 and S2-4) for the desired
communication rate (in bits/s). Selections are:
57.6k bits/s
115.2k bits/s
230.4k bits/s
Processor Restart Lockout
When PRL is disabled (switch S2-2 on), the programmable
controller can restart communication with the adapter in the event of
a communication fault.
When PRL is enabled (switch S2-2 off), the programmable controller
cannot restart communication with the adapter in the event of a
communication fault. In this case, you must press the restart
pushbutton on the front of the adapter module to restart
communication.
Hold Last State
During a communication error, when last state is enabled (S2-1 set to
off), a processor reset will keep the discrete outputs in their present
(last) state; when last state is disabled, the discrete outputs will reset.
The switch assemblies are located under a flip-open cover on the
front of the adapter module.
