The bits in output words 0 and 1 are written during run mode to clear any latched
low or high process alarms. The alarm is unlatched when the Latch Clear bit is
set (1) and the alarm condition no longer exists. If the alarm condition persists,
then the Latch Clear bit has no effect until the alarm condition no longer exists.
You need to keep the Latch Clear bit set (1) until the corresponding Process
Alarm status bit from the input table has been cleared (0). After that you are able
to reset (0) the Latch Clear bit. The module does not latch an alarm condition if
there is an alarm transition from no alarm to alarm while the channel's Latch
Clear bit is set.
Output words 2, 3, and 4 are reserved for manufacturing purposes and must be
set to 0.
The module notifies the host of critical and non-critical module errors using the
Mod_Condition array.
Module errors are expressed as two fields: Mod_Error (3 bits) and
Extended_Error_Info (9 bits). This arrangement is based on the 2085 toolkit:
Description
Module specific error information; specific meaning depends
on the value of the Mod_Error field.
0: No Errors. No need to check the Extended_Error_Info field
1: Hardware Error. General and specific error codes may be
specified by the Extended_Error_Info field.
2: Configuration Error. Module-specific error code specified
in the Extended_Error_Info field. A configuration error
correlates to options that you can change directly (Example:
Input Range or Input ADC Filter selections).
3–7: Invalid
0: Default state
1: Bus watchdog timeout has occurred.
See the description below for more details.
0: Module has not received a valid configuration
1: Module is configured.
