C445 PROFIBUS Bit Mapping Parameters
C445 has option of mapping individual bits in input/output
modules. Below are the bits available for bit mapping.
C445 PROFIBUS Cyclic/Acyclic Writable Parameters
Table 124. Bit Mapping Parameters for Cyclic/Acyclic
Writeable Parameters
Note: For more information about any of the parameters
listed above, refer to System Configuration and
Commissioning on Page 45 or Appendix E.

System Services is one of the selections for an output
data word. The following are decimal values that when
sent to the C445 with the System Services word
cause the C445 to perform the designated function:
0: No Active Service
1: Clear Fault Queue
2: Clear Trip Snapshot
3: Test Trip
4: Re-pair external modules
5: Factory Reset
6: Soft Reset
7: Reset Fault
8: Proof Test
BCM Field Output Control Word is one of the
selections for an output data word. The following are
the bits that control the 3 outputs on the Base Control
Module:
Bit 0: Output 1
Bit 1: Output 2
Bit 2: Output 3 (if a Base Control Module with the
latching relay option is being used, this bit is
used to Set this output)
Bit 3: This bit is only used when a BCM with the
latching relay option is used. This bit resets the
latching relay output.
