DIRECT INPUTS
The
AVERAGE MSG RETURN TIME
is the time taken for direct output messages to return to the sender in a direct input/output
ring configuration (this value is not applicable for non-ring configurations). This is a rolling average calculated for the last
ten messages. There are two return times for dual-channel communications modules.
The
UNRETURNED MSG COUNT
values (one per communications channel) count the direct output messages that do not
make the trip around the communications ring. The
CRC FAIL COUNT
values (one per communications channel) count the
direct output messages that have been received but fail the CRC check. High values for either of these counts may indicate
on a problem with wiring, the communication channel, or one or more relays. The
UNRETURNED MSG COUNT
and
CRC FAIL
COUNT
values can be cleared using the
CLEAR DIRECT I/O COUNTERS
command.
The
DIRECT INPUT 1
to
DIRECT INPUT (32)
values represent the state of each direct input.
