Data Highway Plus Industrial Local Area Network Overview
Communication 
Use Rockwell Software Programming Software to program the PLC controllers over the Data Highway Plus network, or program a PLC controller from its local DH+ link or from a remote DH+ link in the network. This means that a single industrial terminal connected to the network can be used to program all the PLC controllers on all links of the network.
The ControlLogix Communication Interface Module (1756-DHRIO) interfaces two DH+ links to the ControlLogix backplane to provide routing of messages between a DH+ link and EtherNet/IP, ControlNet, DeviceNet, and other DH+ links.
Data Highway Plus modules can also be used to implement a SCADA network.
Benefits
- Includes switches on each interface that make it easy to reconfigure the network as it changes.
- Incorporates network diagnostics that help the user avoid costly downtime and improve network efficiency.
- Allows for use of communication software to provide a Data Highway Plus communication driver to various computer platforms.
