communication of PM571 with serial cable RS232?
I have PM571 controller, i need to upload the program from controller. I tried it via serial cable communication R232 but there is error message display. Please help me to setup the communication and upload the project.
For instructions to upload and download the Control Builder Project from the SD Card to PS501 Control Builder Plus ( Not the CoDeSys programming tool ) see the help files in Control Builder Plus.
As we have said before you CANNOT upload the program from your PLC unless it has already been stored in an SD card. The on board PLC memory only contains compiled software ( the "boot project" ) which cannot be back translated into source code again.
If the PLC does not have an SD card with the Project already stored on it, then you need to get a copy of the program from whoever is responsible for storing the software safely.
If your PLC does have an SD card with the project already stored on it, then posting the details of your error message and exactly what steps you have or have not tried would perhaps be usefull.
