DigitalIOPorts
These variables are used to query and set the digital inputs and outputs of the RF18xCI
communication module. The information for all digital inputs/outputs is always transferred
regardless of whether these are physically occupied or not.

Description
Supplies the states of the digital inputs of the communication
module.
The number of actually existing physical digital inputs depends
on the communication module version being used, the operating
mode of the digital inputs/outputs and on the connected IO-Link
module.
Possible values
00000000 ... 11111111
Binary characters (0, 1) per input
Each position stands for an input of the communication module:
•
Inport00: 1st position (least significant bit right)
•
Inport01: 2nd position
•
Inport02: 3rd position
•
Inport03: 4th position
•
Inport04: 5th position
•
Inport05: 6th position
•
Inport06: 7th position
•
Inport07: 8th position
Depending on the value of the particular position, the corre-
sponding input is at "ON" (1) or "OFF" (0).
