Appendix B Tag Definitions
Input Data Tags
Table 16 lists the input data tags.
C.Out[0].LowLimit REAL Defines the minimum value the output can use in the process. If an output beneath the low limit is requested, the
C.Out[0].LLimit alarm is set and the output signal will remain at the configured low limit.
C.Out[0].HighLimit REAL Defines the maximum value the output can use in the process. If an output above the high limit is requested, the
C.Out[0].HLimit alarm is set and the output signal will remain at the configured high limit.
C.Out[1] AB:1756_IF4FXOF2F
_Struct_Out:C:0 Master structure beneath which configuration parameters for output channel 1 are set. This is the same set of tags as listed for
input channel 0, from
C.Out[0].HoldForInit to C.Out[0].HighLimit , except that this listing applies to channel 1.

I.ChannelFaults INT Collection of individual channel fault bits in one word. Can address individual channel fault via bit notation, such as
ChannelFaults.3 for channel 3. Output channels are bits .4 and .5.
I.In0Fault BOOL Individual channel fault status bit that indicates a hard fault has occurred on the channel. One of the following conditions sets
this bit:
• Calibration is ongoing.
• An overrange condition is present.
• An underrange condition is present.
• Communication is lost with the I/O module.
I.In1Fault BOOL Individual channel fault status bit that indicates a hard fault has occurred on the channel. One of the following conditions sets
this bit:
• Calibration is ongoing.
• An overrange condition is present.
• An underrange condition is present.
• Communication is lost with the I/O module.
I.In2Fault BOOL Individual channel fault status bit that indicates a hard fault has occurred on the channel. One of the following conditions sets
this bit:
• Calibration is ongoing.
• An overrange condition is present.
• An underrange condition is present.
• Communication is lost with the I/O module.
I.In3Fault BOOL Individual channel fault status bit that indicates a hard fault has occurred on the channel. One of the following conditions sets
this bit:
• Calibration is ongoing.
• An overrange condition is present.
• An underrange condition is present.
• Communication is lost with the I/O module.
I.Out0Fault BOOL Individual channel fault status bit that indicates a hard fault has occurred on the channel. One of the following conditions sets
this bit:
• Calibration is ongoing.
• A low clamp condition is occurring.
• A high clamp condition is occurring.
• Communication is lost with the I/O module.
I.Out1Fault BOOL Individual channel fault status bit that indicates a hard fault has occurred on the channel. One of the following conditions sets
this bit:
• Calibration is ongoing.
• A low clamp condition is occurring.
• A high clamp condition is occurring.
• Communication is lost with the I/O module.
I.ModuleFaults INT Collection of all module level fault bits.
