Hi all, I recently had a processor failure and replaced it with a new processor. (I am the same person that had this original post.) To my dismay, the CF card would load since there was no firmware on the new processor. I had to manually load the fireware using software to the processor to make the CF card work. I am now wondering whether I should have backed up the firmware also. (Which I really did not want to do.) It seems there could be trouble if you update the firmware also.   Or should I have loaded all my spare processor modules with firmware? Problem is, I don't know know whether all my plcs (We have about 8) have the same firmware. What would be the best thing to do? They are all the same number and type of processor.   My boss wants to be able to restore the processor without software on a loss of memory or failure. When you save the firmware and program to the CF card does the exact same firmware and program from the CF card get loaded back onto the processor? The reason I ask is the term "Firmware Update" is confusing to me. I don't really what to update the firmware, I just want to copy back what was saved before, not a newer version. Or is that what update on the CF card does?   Thanks Again, Eric      

Thanks for the quick reply Ken. Thats what I needed to hear. I really didn't want to mess with the firmware. Thanks again, Eric

I have about 8 plcs I maintain at our sewer plant. They are all compactlogix 1769-L32s. I have bought AB CF cards for each PLC. The reason I bought the cards is to restore the program to each plc in the event of memory failure due to glitch or battery failure. My boss would rather do it this way instead of using software. (I have RSLogix 5000.) I have a few questions for you members. Once the program is stored, he wants the CF cards removed and stored in a safe place. 1) Is only the program lost on memory failure and not the firmware? or both? I alaways thought the firmware was non-volatile. 2) I am confused by the Firmware Update checkbox. Not explained very well. Should I check this box, Is it really needed, and what is the proper procedure. Thanks, Eric

Thank You for the Quick reply. I didn't realize you could slide the cover off without removing the processor from the rack. I do have things backed up via rs5000 and pc but thought there must be an easier way. (not really explained in manual). Thanks a lot, this really helped. Eric

I have about 8 plcs I maintain at our sewer plant. They are all compactlogix 1769-L32Es. What is the recommended time before you replace the batterys? These units are on normally 24 hrs a day, and do not have the red battery light on. Should you wait until you get the light, or at a certain time interval? Also is there any way to replace the battery without losing the memory, or do you have to back up everything first. ie If you replace the batteries quick enough, will you still lose the memory? I don't remember having to worry about it with the plc5 at our waterplant , but then you didn't have to remove the module from the rack either. Thanks Eric
