DIGITAL OUTPUT MODULE BLOCKS (DOM, DDOM, WDOM)
5-19
DOM 05 I/O Mismatch (MODMMS) ..................................................................................................CWR
DDOM 05 I/O Mismatch (MODMMS) ..................................................................................................CWR
WDOM 05 I/O Mismatch (MODMMS) ..................................................................................................CWR
The I/O mismatch diagnostic compares each slot configured for a digital output module
against the contents of the slot during a power-up or database download. If the slot contains
an intelligent module (analog input, analog output, ICN, MSC or RIO), this diagnostic is
generated.
NOTE: This diagnostic cannot distinguish between an empty slot and a digital I/O
module or between different types of digital I/O modules.
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 11 or
14, MODMM).
ENABLE 0 Diagnostic error is not suppressed and errors are reported to the
System Event block. The error message is reported as I/O
MISMATCH.
DOM 06 Unacked I/O Mismatch (MODMMU)................................................................................. – WR
DDOM 06 Unacked I/O Mismatch (MODMMU)................................................................................. – WR
WDOM 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.
DOM 07 Active I/O Mismatch (MODMMA) ......................................................................................– – R
DDOM 07 Active I/O Mismatch (MODMMA) ......................................................................................– – R
WDOM 07 Active I/O Mismatch (MODMMA) ......................................................................................– – R
If the I/O mismatch diagnostic error is enabled, 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.
DOM 08 DOM module error (DOMERRS) .......................................................................................CWR
DDOM 08 DDOM1 module error (DDOERRS1) .................................................................................CWR
DDOM 11 DDOM2 module error (DDOERRS2) .................................................................................CWR
WDOM 08 WDOM module error (WDOMERRS) ................................................................................CWR
This diagnostic checks to see if the module readback value is the same as the previous result
value. Also, this diagnostic is generated when the select circuit, which is used to
communicate with the module blocks, has a diagnostic error. In this case, all modules would
report this diagnostic. 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.
