Communication issue with PM572
I am trying to communicate Laptop with communication cable(TK 503) and PLC but didn’t get to communicate due to project error after compile the project.
As discussed with soultion partner, uninstalled the software and format the windows 7 and after this process again installed the windows and software.
then he suggest for online process, first of all we have to format the CPU program and then again download the program. After this process, laptop is online with PLC but communication is drop after some changes in program.
As per Solution partner, this problem is due to single COM port on CPU for HMI and PC Communication.
Please advice what could be permanent solution

the issue is really strange, have you the same problem always or is the first time?
However you can try for test to use one other PC, to exclude problems with PC hardware.
Next, you can verify that the FW in the CPU is the last version, to exclude FW problems.
Then are sure that Codesys gateway is active in PC and that you not have other external SW limitation, e.g. in USB ports or serial.
The communication parameters must be the same as the follow set:
