Dear All, I had encounter a problem when i try to open the plc project from Beckhoff CX9020 plc using Twincat 2. There error show that the File'source.dat' could not be read. I had connected the plc from system manager and i able to load the configuration of plc but not the program. I do also tried to file the program file from the flash card but i cant find any .pro file. Is that any possible to read the program or source code inside? Thanks.
