Here is the location of everything: <drive>:\FWUPDATE.S7S\xxxxxxx.upd <drive>:\S7_JOB.SYS Inside the update file is the firmware Inside the S7_JOB.SYS file is "FWUPDATE" and that is how the PLC knows it is expected to update the firmware. Once the memory card is properly copied and only 1 .upd file is in the FWUPDATE.S7S folder, the process for me has been: 1. Memory card -> PLC 2. PLC goes into stop. Power cycle PLC 3. Wait until RUN/STOP is solid YELLOW & MAINT LED flashes. 4. Remove Memory card from PLC 5. Cycle power. Wait a long time until the PLC goes into it's normal power-up state. If it does not enter normal power up state, perform factory reset and reload user program and system configuration. If this does not work, contact support request using the contact box to the right of this message in the forums.

I am going to do a MRES on CPU and everything you suggest, i hope this will be the solution. Thank you son much. Regards

The time from the power up to the led's changing to a steady state (not flashing) is quite long. It is like watching water boil.... 3rd power cycle (not always required, but a good idea) is to run the program with the new firmware
