Does anyone know how to load a program into the flash memory of a Modicon Quantum 434 Processor? I'm using the ProWorx Nxt programming software. After going onlline I tried to do it via ethernet with the processor stopped of course, and it locks up and gives a communications time out. I then thought that maybe when it tries to flash the memory that it looses control of the Ethernet card so I used my Modbus cable and got online with that and tried it and got the same result. Am I doing something wrong? Every time the processor looses power it reverts back to an older version of the program because that is what is loaded into the eeprom.
