ICN COMMUNICATION BLOCK
4-15
51 I/O Module Mismatch (MODMM).......................................................................................– – R
If the module missing or invalid diagnostic is suppressed, this status indicates if the diagnostic
is or is not active (unsuppressed form of I/O module mismatch active). The unsuppressed
mismatch condition is used to determine if there is an active mismatch condition when
switching the diagnostic from suppressed to enable. The status can be read as follows.
NO 0 Diagnostic error is active.
YES 1 Diagnostic error is not active.
52 ICN Address (ADDR) .........................................................................................................– – R
This value represents the actual switch setting (0 to 15) for this ICN communication module.
53 Board Number (BOARD) ...................................................................................................– – R
This is the board number that the physical module is configured for. Currently, the only valid
value is one.
54 Slot Number (SLOT) ..........................................................................................................– – R
This is the slot number that the physical module is configured for. The valid values are 32 for
occurrence one; 30 or 29 for occurrence two; and 28, 27, or 26 for occurrence three.
55 Terminating Source (TERM) .............................................................................................– – R
This value indicates if the Model A ICN module automatically terminated the ICN. Note that a
check is made each time the ICN is restarted. The Model A ICN module with the lowest
address automatically terminates unless there are MOD 30 instruments already terminated on
the network.
FALSE 0 ICN module is not terminated.
TRUE 1 ICN module is the terminating source for the ICN.
