Field Description and values
Quality Force When this bit is set to '0', the quality of the protocol objects for EDS001
module is set as Offline irrespective of CPU state. The state table follows:
CPU state
STOP
STOP
RUN
RUN
Note: You can use this bit in runtime logic to interlock quality state with other
interlocks. If you set the mComreq_Setup[24] = 0, then Quality Force will not be
applicable and Quality will be driven by the CPU state.
Effective with firmware version 1.10, events are generated even when the
Quality flag is offline, and the appropriate quality status is then updated to
the Master. Prior to firmware version 1.10, the offline state of the Quality flag
prevented this.
Unused Unused

0 User selection of Time Source for time stamping of events.

Default value is set to 0.
The time synch command from the DNP3 master will set the local
time for both the EDS001 module and the CPU. However, the
timestamp for events will be based on the selection above.
