I have an illuminated BATT LED on the front of my Programmable Logic Controller (PLC), what should I do? David S. of Fleetwood
Seeing the BATT light on is a big deal and means your CPU battery in your PLC is failing, which could result in losing your PLC program. You should upload the program from the PLC as soon as possible or risk losing it and needing to rebuild the project from scratch.
Contact me or our services team for a quote on a replacement CPU battery, and to assist with program upload. Act soon so you do not risk losing your program and causing costly downtime!
