CHAPTER 6: ACTUAL VALUES STATUS

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 can 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.
