Are you using the s7-1214c firmware or perhaps another PLC's firmware was upgraded in the past? Maybe just copy the latest firmware onto your memory card again according to the firmware update instructions. I have noticed that sometimes when I install the MMC into my PC and PLC it does not work the first attempt. It also takes longer to update each time I update one - at least, it seems that way.
