The POL[axis] command is a 17-bit value used to set or read the input mode and/or input/output logic of various signals. Use table POL command below to see descriptions of each bit setting.

POL command

The polarity can also be set for the digital inputs, digital outputs, and configurable I/O. The DIP command can be used to toggle the polarity of the digital inputs and the DOP can be used to toggle the polarity of the digital outputs. For these 0 = Negative logic, 1 = Positive logic.

The IOP command is 2-bit and can be used to toggle the polarity of the configurable I/O.  Bit 0 sets the input logic and Bit 1 sets output logic.  See table IOP command below.
