Run Flashing 7 times error code 300 or 301, 140CPU534 14B

My CPU 534 14B doesn't work. Run led flash 7 times. no possible MB+ connection, ERROR code meanings: 300 EXEC not loaded or 301 EXEC Checksum. It was working well then nothing can't even communicate with it. reset power without battery, download an other firmware (EXEC) 1.11 instead of 1.16, same problems. Someone can help on that case? I'm using NXT as programming software. Edited 26 Dec 2014 by Claude123

You need to load the EXEC trouth Mb+ (you must use address 1) or Modbus. If it's not possible then you can let it repair by Schneider Electric - costs about 50% of neu PLC :(

Thanks Sparky According to Schneider spécialist, EXEC transfert is good but PLC does'nt want to start. There is a "failed" in transfert progress utility screen saying that: "Exit Kernel Mode:Failed". Schneider asked me to send the PLC for repair or exchange....new one cost is 13000$CAD...so.

Finally my CPU is still under warranty, no charges and a credit to buy a new one....
