05 Module missing or invalid (MODMMS) ............................................................................CWR
This diagnostic compares each slot configured for a MSC communications module against the
content of the slot during a power-up or database download. If the slot is empty or the
installed module does not match the configuration, this diagnostic is generated.
SUPPRESS 1 Diagnostic error is suppressed. Acknowledgement status remains
clear. Even though the I/O mismatch diagnostic is suppressed, the
actual I/O mismatch condition is still determined (see Attribute 30,
MODMM).
ENABLE 0 Diagnostic error is not suppressed and errors are reported to the
System Event block. The error message is reported as MODULE
MISMATCH.
06
Module Missing Unacked (MODMMU) ............................................................................ – WR
If the module missing or invalid diagnostic is enabled, this status indicates if the diagnostic is
or is not unacknowledged. The status can be acknowledged or read as follows.
NO 0 Diagnostic error is acknowledged.
YES 1 Diagnostic error is unacknowledged.
07
Module Missing Active (MODMMA)..................................................................................– – R
If the module missing or invalid diagnostic is enabled, this status indicates if the diagnostic is
or is not active. The status can be read as follows.
NO 0 Diagnostic error is not active.
YES 1 Diagnostic error is active.
