Controller Address
When multi-controller connect with a serial port bus (485 bus is frequently applied; 232 bus can only connect with one device), the controllers can be distinguished by its IP address. When multi-user is selected, this function can not be changed. But network controller address just need setup 0.

When TCP/IP converter connects with computer, the 485 port of converter can connect with multi-controller. If serial port controller connects with computer which does not have 485 port, a 232/485 converter should be adopted.
