RS-485 Application
A typical RS-485 application for the TCC-100 series is shown in the
following figure. In this scenario, two TCC-100 units are used to connect
two PCs to an RS-485 network. The third TCC-100 is used to connect the
PLC, which is designed for the RS-232 interface, to the RS-485 network.
In this way, both PCs are able to interact with the PLC and the LCD
display.
