ANALOG INPUT MODULE BLOCKS (VCIM, TIM, RIM, WRIM)
5-40
06
Unacked I/O Mismatch (MODMMU) .................................................................................– WR
If the I/O mismatch diagnostic error is enabled, the unacknowledged I/O mismatch diagnostic
status indicates if the diagnostic is or is not acknowledged. The status can be acknowledged
or read as follows.
YES 1 Diagnostic error is unacknowledged.
NO 0 Diagnostic error is acknowledged.
07
Active I/O Mismatch (MODMMA)......................................................................................– WR
The active I/O mismatch diagnostic status indicates if the error is active even after
acknowledgement. The status can be read as follows.
YES 1 Diagnostic error is active.
NO 0 Diagnostic error is not active.
08
I/O communications error (COMMERRS) ....................................................................... CWR
The I/O communications error diagnostic checks the status of communications between the
input module and this block and looks for checksum errors. This diagnostic is also generated
when the select circuit, which is used to communicate with the module, has a diagnostic error.
In this case, all modules would report a communications error diagnostic.
Error counters are
stored in the interface block as one of four different error types.
The diagnostic can be
suppressed or enabled as follows.
SUPPRESS 1 Diagnostic error is suppressed. Acknowledgement status remains
clear.
ENABLE 0 Diagnostic error is not suppressed and errors are reported to the
System Event block.
09
Unacked communications error (COMMERRU).............................................................– WR
If the communications error diagnostic is enabled, the unacknowledged diagnostic status
indicates if the diagnostic is or is not acknowledged. The status can be acknowledged or read
as follows.
YES 1 Diagnostic error is unacknowledged.
NO 0 Diagnostic error is acknowledged.
10
Active communications error (COMMERRA) .................................................................– WR
The active communications error diagnostic status indicates if the error is active even after
acknowledgement. The status can be read as follows.
YES 1 Diagnostic error is active.
NO 0 Diagnostic error is not active.
VCIM 11
VCIM module error (VCIMERRS)...................................................................................... CWR
TIM 11
TIM module error (TIMERRS) ........................................................................................... CWR
RIM 11
RIM module error (RIMERRS) .......................................................................................... CWR
WRIM 11
WRIM module error (WRIMERRS).................................................................................... CWR
The module error diagnostic is a status indication for the extended error (EXTERR attribute
18) code. The diagnostic can be suppressed or enabled as follows.
SUPPRESS 1 Diagnostic error is suppressed. Acknowledgement status remains
clear.
ENABLE 0 Diagnostic error is not suppressed and errors are reported to the
System Event block.
