Yeh i've tried it with the correct power and that's the position i'm in now from the top of this topic feed, I'm guessing something is damaged too but I have little experience following circuit boards through like this

Hi All, That error makes sense to something I've been informed today, someone had accidentally put 110V dc on the 24V terminals, I stripped the PLC down to find some of the pins on the power card burnt (I think the output pins of the power card) i cleaned the connections up and checked the fuses (which were fine). Other than that i cant visually see any other issue, That's obviously not to say there isn't an issue, I just don't know where to look from here. Again, any thoughts would be grateful Gob12345

Ok, I've attached it to this post Any suggestions will be very much appreciated RWR_18_02_13.RSS

Hi all, I have a fault on my micrologix 1200 which is stopping the PLC from going into run mode. I can connect to the plc as well as download to it but as soon as i put it into run mode the fault comes up I searched the error code (21H) and its "Bad MSG file parameter for building message" Anyone know what could be causing this? I'm pretty confident that I don't have any MSG bits in the program, I'm using rs logix 500 (if that helps) Thanks Gob12345
