Current measurement and error detection
The V-P (voltage pulse) blocks each have two CT inputs, and can be used for
continuous current measurement or heater and actuator burnout detection,
overcurrent detection, and short circuit detection.
Settings for both CT1 input and CT2 input groups must be made for each block:
A2, B2, A1, and B1.
