Hello, I am trying to make a PLC-program read a barcode scanner connected to the CORE via the USB connection. For this, I am using the SysCom library and wants to add the connection /dev/ttyACM1 as COM1 in the PLC. However, I can not edit plc_system.cfg to add this port. It is write protected in the web-interface. Using WinSCP with WebDAV protocol generates an "403 Forbidden"-error and the file cannot be edited from there either. How do I edit plc_system.cfg? Or or there other ways of adding the serial connection /dev/ttyACM1 to the PLC project? CORE, PLC, and WORKS all version 1.20. Thanks, Daniel
