1. General
1.1 Communications data
Class A
Important: The display device (IO-link device)
must always be connected to a separate
power supply (AC or DC)!
1.2 Features
1.3 IO – Link interface
Usuable IO-Link-Master
All IO-Link-masters, which support IO-link Standard v 1.1.
Connection of the IO-link interface
At terminal 34 (L-) and terminal 35 (L +) the supply voltage of the IO-link interface and at terminal 36 (c/q)
the IO-link data line is connected to the port of the IO-link-master. Figure 1 shows the pin assignment of a
standard M12 connection plug.
The display device (IO-link device) must also always be connected to a separate power supply (AC or DC).

2.2 System Commands
A system command is a write-only parameter that causes an action in the device. To invoke the desired
action, the corresponding value must be written to index 2, subindex 0. If the desired command is a static
command (s), this command remains active until the corresponding value is written again to index 2,
subindex 0. By resending the command, the action is terminated.
2.2.1 Predefined commands
Description of the action
Reset all parameters to factory
setting.
