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 2year 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 knowing that I have modicon plccmicro (pl7 micro) with a memory card
