Hello Everybody!
In our software, we have a feature "Hand mode". The meaning of this is for example if a pump is in "hand mode", we can start the pump manually but on the other hand, if the pump is in "auto mode", PLC can start according to schedule, and so on. If we leave the pump in "hand mode" then PLC can be set to auto mode and continue the work. My question is, should PLC set the pump to "auto mode" and continue the work if possible or the pump should be excluded from the operation (the pump might have issues, so the operator leaves it to "hand mode")? Which one is a reasonable answer and why or it totally depends on the person who is doing the spec?
