Why it’s not possible to access over serial PGU or S-Bus to the PCD, error message ‘Error 99: Can’t open port comx’ is shown in the PG5 debugger?
We have received the information that on an application it was not possible to access with PG5 version 2.1.420 over serial line (RS232) in PGU or S-Bus mode to the PCD and the message: Error 99: Can’t open port comx was shown in the debugger.
The reason why it was not possible to access the PCD was the fact, that the com port was used from another application at the same time.
The application which have used the same serial port was the software SoMachine from Schneider Electric.
To be able to go online in this situation, it’s necessary to stop the software SoMachine from Schneider Electric.
