flash memory


Recommended Posts


Because lots of our plcs are in remote areas we have to make changes remotely, unfortunatley I have found doing a burn to memory is fraught with danger if something goes wrong and no one is there. It would be great if when you download without burning the program in the flash is not effected, so if the backup battery goes flat on the next power up the plc loads the flash memory program basically two differnt programs in the same plc.
