Posted 14 Mar 2020 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. 1 person likes this Share this post Link to post Share on other sites
Posted 26 Apr 2020 This error is poped up because there is no source code in your PLC, as a result you cannot upload the program from PLC. The last programmer didn't download the source code and he or she just downloaded the binary files Share this post Link to post Share on other sites
