2. DH-485 Industrial Local Area Network Overview DH-485 is a local area network (LAN) designed for factory-floor applications. DH-485 allows for connection up to 32 devices, including SLC 500 and MicroLogix 1000 controllers, color graphics systems, and personal computers. The DH-485 link together with auxiliary RS-232-C (DF1 protocol) links make up the DH-485 network. With RSLinx software installed on a PC, communication with other nodes on the network is possible. Using SLC 500 Programming Software, program SLC 500 controllers over the DH-485 network. This means that a single PC connected to the network can be used to program all the SLC 500 controllers on the network.
