I got through a mitsibishi FX2N PLC and when i turned it on it was giving battery error. So when i checked it with system and run diagnostic so i found the same error. By visual inspection i saw that there us no battery in it and someone has taken it out. So my question is that how we are going to reset the PLC when the battery was not intact for how long whixh we dont know. I have the copy of program with me to upload it to plc but the actual issue is battery error.

Thanks  crossbow and glavanov for your reply. Yes i had the copy thats why i am saved :D
