Description
Enable input. If false, the instruction does not
execute and outputs are not updated.
Default is true.
The first analog signal input to the instruction.
Valid = any float
Default = 0.0
The second analog signal input to the
instruction.
Valid = any float
Default = 0.0
The third analog signal input to the instruction.
Valid = any float
Default = 0.0
The fourth analog signal input to the
instruction.
Valid = any float
Default = 0.0
The fifth analog signal input to the instruction.
Valid = any float
Default = 0.0
The sixth analog signal input to the instruction.
Valid = any float
Default = 0.0
Bad health indicator for In1. If In1 is read from
an analog input, then In1Fault is normally
controlled by the fault status on the analog
input. If all the InnFault inputs are true, the
instruction sets the appropriate bit in Status,
the control algorithm is not executed, and Out
is not updated.
Default = false
Bad health indicator for In2. If In2 is read from
an analog input, then In2Fault is normally
controlled by the fault status on the analog
input. If all the InnFault inputs are true, the
instruction sets the appropriate bit in Status,
the control algorithm is not executed, and Out
is not updated.
Default = false
