Hi guys we had a problem with our ML 1500 (LRP). The ML is connected to a PV 600 standard thru DH 485 channel 1. The PV gave a fault “no nodes found on network” I connected to the ML and the program was gone. The ML did not fault out but instead had the attached program I was able to download and post. The ML also has a memory module That I would think the PLC should boot from if there is a fault attached is the program and the screen shot of the processor status Mem Module. Any help as how this could have happen and why the PLC did not fault out, as well as where did the program come from? Thank You
