Configuration Of The Safety Position Of Pilot Valves For Bus Error; Teach Function (Calibrating The End Position) - Burkert 8695 Operating Instructions Manual

11.11 Configuration of the safety position of pilot valves
for bus error
If a bus fault occurs, the bus LED may assume the "Green flashing", "Red flashing" or "Red" status.
(For a description see "Status of the bus LED", page 59)
The valve safety position and safety module attributes can be used to configure the pilot valve in the event of a bus fault.
If a bus fault occurs, the configuration data of the pilot 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.
