The bits in the IO Status Word (F01) each correspond with one digital I/O as shown below. The update rate of the individual bits in these registers
differs depending upon the I/O.
The IO Status Word (F01) is always active and shows the value in the Digital I/O State parameter for all digital I/O configured as inputs.
See T24 Digital I/O 01 State (F03).
The Digital I/O State parameter shows the state of digital I/O on the drive. All I/O except Digital Input 11 (Keypad Run Button), Digital Input 12 (Keypad
Auxiliary Button), Digital Input 13 (24 V Supply Input) and Digital Input 14 (Keypad Stop Button) use IEC61131-2 logic levels. As default the inputs use
positive logic, and so the state parameter is 0 if the digital I/O is low or 1 if the digital I/O is high. Input Logic Polarity (F02) can be set to zero to change
