The addresses listed in the table “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
acyclically via Explicit Messages.

13.12 Configuration of the device
13.12.1 Configuration of the safety position of solenoid valves during a
bus error
The valve safety position and the safety mode attributes can be used to configure the solenoid valves in the
event of a bus error.
The configuration data of the (behaviour of) solenoid valves in case of a bus error 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.
