Table C.19 Modbus Register Map
Note 1: Summary RTD Temperature Addresses
can contain the following diagnostic
codes:
7ffeh = Fail
7ff0h = Not Attached or Not
Available
Note 2: Individual RTD Temperature Addresses
can contain the following diagnostic
codes:
8000h = RTD shorted
7fffh = RTD open
7ffch = SIMPRO-100-RTD
Communication Failure
7ff8h = SIMPRO-100-RTD
Self-Test Status Failure
7ff0h = RTD Not Attached or Not
Available
Note 3: RTD Temperature Range Depends on
the relay temperature preference
setting.
Note 4: The event type is reported as a
character string as shown in the table
below:
