Description:  Equustek's gateway interfaces your Modbus TCP/IP Network to A-B's Data Highway Plus DH+, extending the life of Allen-Bradley PLCs without Ethernet Interfaces. The DataLink solution allows applications such as RSLogix, RSLinx, and RSView to access devices on a DH+ network from an Ethernet/IP LAN, enabling users to run MMI applications or program and monitor PLCs on a DH+ network from an Ethernet LAN station. Other MMIs tested include Wonderware, Kepware, and Intellution. The DL4500-MEDH+ combines the Lantronix Ethernet Microprocessor with Equustek's DH+ token-ring technology.
