Dear all,
I would like to control motorised operated valves using PLC which is in turn is triggered by a manual switch . I’m now adding a scada system and want to be able to trigger both the PLC using the manual switch and the scada ( simply by triggering a digital input signal ‘1’). What are your suggestions for achieving this and how can I interlock these two modes
