Operating instructions IO-Link Master IOLG2PN-03208R01 – PROFINET
System integration and configuration
Safe state
This function is an extension of an output configuration of the relevant port
pin. For each port pin, you can define a safe state which should be as-
sumed if bus communication is lost.

Bit mapping and function of the modules
IO-Link modules scheme
IO-Link modules are structured according to the following scheme:
• IOL_I/O_x/xBytes
Description
I/O
• I: Input data
• O: Output data
• I/O: Input and output data
x/xBytes
Amount of process data used. The amount should be
equal to or greater than the process data length of the
IO-Link device.
Table 13: IO-Link module scheme
Standard I/O modules
If a port is configured as a standard I/O, first you must move one of the
modules “Input pin 2”, “Input pin 4”, “Output pin 2 and ”output pin 4” from
the catalog into the configuration. The process data of the individual ports
are mapped in this module.

This module enables you to configure the startup behavior after an actua-
tor short-circuit.
• Bit set: Automatic restart
• Bit not set: No automatic restart; restart must be triggered manually.
