RIO bus
As soon as the configuration is correct and a master control system is connected, the bus LED switches from red
to green. Differences from the planned Profinet configuration can be found in the ModulDiffBlock. There are no
configuration or parameter-setting telegrams for any other bus systems.
After the error has been rectified the valve terminal must be reset by briefly shutting down the supply
voltage.
