All,
I've had a recurring problem with the 1756-L72 ControlLogix5572 Controller. The processor will show that it is in run mode on the card itself (green LED) but the software doesn't show any mode (no green light but displays "run mode"). I tried toggling the mode in the software and received the message "unable to go into run mode". The "I/O OK" LED shows green, the "Controller OK" LED shows green and the "Energy Storage" LED shows no color. I tried cycling power (no change). I ended up removing the Energy Storage Unit", cycling power, reinstalling the ESU and downloading the program. Does anyone have any further information on this. I've had this happen a few times on different controllers. Thanks in advance!
