I just updated the firmware in the c-mores and had a new program downloaded and started to get the message--Nak recieved from PLC. I went back and downloaded the old program but the message still comes up now. I changed out the e-comm and have the latest firmware installed. I am on a level one network which has 7 DL06, 6 c-more and contrologix but untill now I had no trouble. It is still updating the screens since I put the old program on, with the new program it froze the e-com card so I could see it in net-edit but trying to see the PLC it would say I was in trouble. Should note that this is the second e-com card in the PLC I was using just to talk to the c-more screens, I use the other for programming and recieving information from our level 2 system. Any Ideas? ??? DAY 2---Now I am getting this message from another PLC but it is not updating the screens. We use this to monitor temperatures on a process line so I really need any ideas.
