  The serial port configured in the communication configuration window cannot be configured again using the script. RS232 and RS458 (or RS422) can be used simultaneously, but RS422 and RS485 are mutually exclusive.For example, when the communication port is configured with COM1-485, the script can only open COM1-232, but not COM1-485/422. Similarly, when the communication port is configured with COM2-485, the script can only open COM2-232, but not COM2-485.
