Downloading Your Program

You can download programs via a direct cable connection between your PC and the controller.
The cable should not exceed 3 meters in length.

Connecting the Controller to the PC

•
Connect the controller to your PC using the communication cable as shown below.

CANbus

The CANbus port is located on the side of the controller, as shown in Figure 6, page 14. Via
this port, you can create a decentralized control network of up to 63 controllers. This is
sometimes called a multi-master network. In such a network, CANbus enables inter-PLC data
exchange.
Unitronics' CANbus control network is run by a separate isolated power supply that is not part
of the network power supply.

The RS232 serial port is not isolated.
