Hi,
I have a system which was not used for few years and now planning to use it/commission it. It is a Control logix platform, 1756-L61 ControlLogix 5561 rev 13.25. The battery fault is ON . As per AB literature 1756-L61 SERIES "A" should use battery 1756-BA1 and SERIES "B" should use battery 1756-BA2 if not then CPU could be affected.
Could anyone pls advise how to find out the series of a CPU, i could find only the above information from controller properties.
Thanks
