Working with A2SHcpu and something went wrong. Cleared PLC memory and I have an error code 17 (ROM). I don't know how to clear this. I have tried creating a new project and parameters but when I try downloading parameters only it gets to about 13% then says complete. When I read the parameters back from the PLC they have not changed and are still at factory default. There is no memory card that I can see in the processor.
Any help or guidance would be much appreciated.
