I have a PLC5-40 with 1771-IL card. I need to change one of the channels from its current configuration of 0-5vdc|0-20 ma to the new required configuration of 1-5vdc|4-20ma. I made the change and accepted the edits but then it asked me if I wanted to download the I/O channel change. Is this a PLC download? The PLC is live now and if its a download I would shut down various equipment. The documentation is not clear what is going to occur if I answer yes to this and its not clear if I have to do it. (its a card in the local chassis).
