DH485 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 DH485 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 DH485 network. This means that a single PC connected to the network can be used to program all the SLC 500 controllers on the network. Options on each interface allow for easy reconfiguration of the network when it changes.
