I have an older (2006) Panasonic FP-X C14R that i need to connect to. I have zero experience with Panasonic PLC's and the FPWIN Pro7 software. When i try to upload the program from the PLC to my laptop i keep getting a error message that reads (The target data does not exist in the comment memory) i know i have a connection because the software displays weather the PLC is in run or program. Anyone know why this i keep getting this error? I have plenty of experience with AB but none with this brand.
