Connect the master and DeviceNet Communications Unit, and then use RS-
485 communications to connect the Temperature Controllers divided into mul-
tiple blocks. Connect the DeviceNet Communications Unit to any one of the
blocks. Connect each block with the Terminal Unit on the end.
The total cable length for RS-485 communications can be up to 500 m, so
Temperature Controllers located at a distance can be operated using a single
DeviceNet Communications Unit.
