Sunchos Posted May 11, 2013 Report Share Posted May 11, 2013 Good day to everyone! Got an issue trying connect to v1040-t20b via modbus serial. I'm initiating data exchange through usb port (and starting to realize that, eventually, there is no any response from Uni, 'cause com1 supports only PCOM). Than i looked through info mode menu: com1 - pcom, com2 - pcom, com3 - modbus. And at the side panel there are port1 and port2 only. So, there is no such as 'port3' or... com3. How can i configure usb port to recognize modbus commands? Quote Link to comment Share on other sites More sharing options...
