Rick Webster Posted November 15, 2021 Report Share Posted November 15, 2021 Lost our program during Generator Test (switching to generator power). Has worked fine last 3 years. We have a V570-57-T20B-J controller. It went to a "text" only "Stop Reasons: No Application. Status: Idle. We have received a "software" program from distributor to upload from PC to PLC but are having no luck after 'physically' connecting PC to PLC accomplishing an upload. I am very new to this PLC world and need lots of help. Any suggestions, info available for proper steps? P.S. We also have an identical(redundant) program and boiler next to this one. Could we download program from it onto a SD card and load it onto our failed PLC?? Thank YOU! Quote Link to comment Share on other sites More sharing options...
