help plc micro error light always flashing!

[anyaddress]

Hi all plz I need ur help, I have a modicon micro plc and the error lamp is flashing (red colour), this happened before from 1year I just changed the backup battery ,reprograme the plc with the application and every thing is fine and machine back to work normally, now I replace the battery with a new one (knowing that battery low level indicator doesn't light),the error led is still flashing but the machine just working fine except for error flashing, I reprogram the plc with the original application and run it nothing happen the error still flashing but the machine is working, using my pl7 micro software I go to diagnostic mode and it indicates that the last fault is caused by battery (I replaced battery,reprogramme plc but error is still flashing ) any suggestion to know why error lamp still flashing knowing that I have modicon plccmicro (pl7 micro) with a memory card thank you

Did you power cycle the PLC or stop it and start it after the battery was replaced? That error latches on.

I'd have to dig up the CD with the manual, but there is a list of reasons that would apply. I'll find the manuals on the TSX Micro and post them later today.
