The addresses listed in the table above ("Static input assemblies") can be used as path data for the Produced
Connection Path attribute of an I/O connection.
Nevertheless, by using this address data, the attributes combined in the assemblies can also be accessed acycli-
cally via Explicit Messages.

12.12. Configuration of the device
12.12.1. Configuration of the safety position of solenoid valves if
bus error
The valve safety position and safety module attributes can be used to configure the solenoid valves in the event of
a bus error.
If a bus error occurs, the configuration data of the solenoid valves can be accessed acyclically via Explicit Messages.
• The Get_Attribute_Single service stands for a read access of the configuration data.
• The Set_Attribute_Single service stands for a write access of the configuration data.
