Isolated Analog I/O Module Tag Definitions Appendix A
Ch[x].FaultFinalState REAL Value to which the channel changes if the following
events exist:
• Connection is lost
• Time defined by the C.Ch[x].FaultValueStateDuration
tag has been exceeded
Any
0.0 = default
Ch[x].ProgValue REAL Value to which the channel changes if the following
events exist:
• Module transitions to Program mode
• C.Ch[x].ProgMode tag is enabled Any
0.0 = default
Ch[x].LowSignal REAL Signal value that lets you scale signal units (V, mA) into
Engineering Units.
Corresponds to the C.Ch[x].LowEngineering tag. That is,
this tag’s value is scaled to the lowest Engineering Unit. Any value less the
C.Ch[x].HighSignal tag value.
Current input type: 4.0 = default
Voltage input type: -10.0 = default
Ch[x].HighSignal REAL Signal scaling value that lets you scale signal units (V, mA)
into Engineering Units.
Corresponds to the C.Ch[x].HighEngineering tag. That is,
this tag’s value is scaled to the highest Engineering Unit. Any value greater than the
C.Ch[x].LowSignal tag value
Current input type: 20.0 = default
Voltage input type: 10.0 = default
Ch[x].LowEngineering REAL Low engineering scaling point
Corresponds to the C.Ch[x].LowSignal tag value. Any lower than the
C.Ch[x].HighEngineering tag
Default values:
• 0.0 for current
• -10.0 for voltage
Ch[x].HighEngineering REAL High engineering scaling point
Corresponds to the C.Ch[x].HighSignal tag value. Any higher than the
C.Ch[x].LowEngineering tag
Default values:
• 100.0 for current
• 10.0 for voltage
Ch[x].LowLimit REAL LowLimit setpoint below which the output cannot go
when Clamping is enabled. Any lower than the HighLimit
0.0 = default
Ch[x].HighLimit REAL HighLimit setpoint above which the output cannot go
when Clamping is enabled. Any higher than the LowLimit
0.0 = default
Ch[x].Offset REAL Compensates for any known error on the sensor or
channel to which the sensor is connected. The value is set
in signal units. Any
(We recommend that you use a
small value.)
0.0 = default
