A.11 Transducer fault and alarm mapping
Read-
only access to transducer fault and alarm informa�on will be provided in a block of 100 registers
and coils. These can be accessed as discrete inputs using func�on code 02 or as input registers using
func�on code 04. Reading them as discrete inputs provides a simple bit result for each, 0 for off and 1
for on. Reading them as input registers provides informa�on on their NAMUR status, as follows:
0 = off,
1 = fault,
2 = maintenance required,
3 = service in progress.
Alarm 1 and alarm 2 are not faults and can only be off or on.
The fault, maintenance required, and service in progress faults provide a summary of the other states
and can only be off or on. The registers are assigned as follows:
