Hi,
In a migration project from S5 to PCS7 we are going to use retrofit connectors from Siemens to do a Control Module IO test in a weekend.
The question I have is, we are going to disconnect the S5 connectors and connect them into the retrofit connectors that are connected to the S7-400 PLC.
After the IO tests during the weekend we are going to reconnect everything on the S5 for the production of monday...
Just wondering, disconnecting and connecting... I think we better do this with the power shutted off ? When disconnecting 4-20mA closed loops from an S5 IO card, are these old cards ok with that ?
But still, I think we need to shut off the closed...
What do you guys think how to retrofit test and return to old situation...
Thanks for tips,
Kind regards,
Combo
