Software Configuration Tags
This appendix lists these categories of 1756-CFM data structures:
• Configuration - This structure is used to write configuration upon
insertion and to make changes during module operation.
• Input - This structure displays the current operational status of the
module.
• Output - This structure is used to modify module operation and override
the outputs.
Configuration Structure
You must use the Configuration tags to alter module configuration. Table 14 lists
and defines 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
C.Ch0PreTrigger Decimal BOOL
Enables the PreTrigger on Channel 0 for full flow.
Set the bit to 1 to enable it
C.Ch1PreTrigger Decimal BOOL
Enables the PreTrigger on Channel 1 for full flow.
Set the bit to 1 to enable it
C.Operations[0].OperationalMode Decimal SINT
Sets the module’s operational mode.
0 = OFF
1 = Totalizer Mode
2 = Non-Resettable Totalizer Mode
3 = High Resolution Frequency Mode
