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.
