We're using a 64K memory SLC 5/04 CPU. One day the program suddenly got erased from the CPU, causing the process to activate the emergency stop. We plan on migrating the project to ControLogix but we're still missing some hardware. Meanwhile, we decided to change the CPU, being the only difference the memory. We installed the same CPU, except the new one was a 32K memory CPU instead of 64K. After downloading the program and establishing connection with the Panel View that it's connected to, the PLC automatically changes nodes after some hours or days, losing once again connection with the Panel View.
I'm not a PLC expert and correct me if I'm wrong, but I would guess that the problem is the new CPU's memory because we never had this problem with the original CPU.
Any help is appreciated, thank you!
