Whilst upgrading firmware to an allen bradley processor (1756-l55/A ) lost power to pc. does this cause a fatel error or can the processor be saved?.:mad:
 
Depends on the status of the PLC after powerup. If the PLC has a solid red ERROR light on or if you cannot see the processor in the PLC rack or directly through RS-232 then you will probably need to send it to Rockwell for replacement. Otherwise you should be able to re-download the firmware. Good luck.
