The addresses listed in the table above ("Static input assemblies") can be used as path data for the Produced Con-
nection 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
during a 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.
