Appendix A
Ch[x].CalOutputHighRef
BOOL
Data value change that transitions the channel to produce
the High Calibration Reference Point for the current
C.Ch[x].OutputRange tag value.
• 0 = Do not Output Cal High
Reference
• 1 = Output Calibration High
Reference Signal
Do not set his tag and the
CalOutputLowRef tag to 1
simultaneously.
Ch[x].CalLowRefPassed
BOOL
Data value change that indicates that the O.Ch[x].Data tag
contains the recorded Low Reference value for the
channel that is used by the module in Calibration.
• 0 = Not sending Recorded Cal
Low Ref
• 1 = Sending Recorded Cal Low
Reference in Output Data for
Calibration Verification
Ch[x].CalHighRefPassed
BOOL
Data value change that indicates that the O.Ch[x].Data tag
contains the recorded High Reference value for the
channel that is used by the module in Calibration.
• 0 = Not sending Cal High
Reference
• 1 = Sending recorded
Calibration High Reference
Signal in Output Data for
Calibration Verification
Ch[x].CalFinishCalibration
BOOL
Data value change that triggers the channel to complete
the Calibration procedure, applying the Valid Low and
High References received.
Channel exits the Calibration state if successful.
• 0 = Channel not triggered to
complete the calibration
procedure
• 1 = Channel triggered to
complete the calibration
procedure
Ch[x].Data
REAL
Channel data in scaled Engineering Units.
Any positive or negative value.
Determined by how you set the
scaling parameters on the channel.
