Software Configuration Tags
This appendix lists the following categories of CFM data structures:
 Configuration - This structure is used to write CFM configuration
upon insertion and to make changes during module operation.
 Input - This structure displays the current operational status of the
CFM module.
 Output - This structure is used to modify module operation and
override the outputs.
Configuration Structure
You must use the Configuration tags to alter CFM module configuration. This
table lists and defines CFM Configuration tags:

Name Style Data type Definition
C.ProgToFaultEn Decimal BOOL Sets outputs to selected Fault state when the
owner-controller is in Program mode.
0 = outputs use Program mode setting
1 = outputs use fault mode settings
C.ChannelCfgBits for Channel 0 Binary SINT
C.Ch0ProverDirection Decimal BOOL Defines the direction of a prover connected to Channel 0.
0 = unidirectional prover
1 = bidirectional prover
C.Ch1ProverDirection Decimal BOOL Defines the direction of a prover connected to Channel 1.
0 = unidirectional prover
1 = bidirectional prover
C.Ch0LowFreqClear Decimal BOOL Enables the minimum detectable frequency level for
Channel 0.
Set the bit to 1 to enable it
C.Ch1LowFreqClear Decimal BOOL Enables the minimum detectable frequency level for
Channel 1.
Set the bit to 1 to enable it
