A: The ANC-100e: Allen-Bradley Data Highway Plus (DH+) to Ethernet Converter can easily connect your Kepserver on Ethernet to communicate with all nodes on your Allen-Bradley DH+ Network including multiple PLC-5s and SLC 5/04s.

Please note that you don’t require Rslogix500 for the ANC100E to work with Kepserver. There is no limitation from the Ethernet side on number of nodes connected and number of PLC-5s and SLC 5/04 nodes on DH+. Please note that communications may slow pending on amount of communications required.

All message instructions (read/write) must come from Ethernet side and be sent to the DH+ nodes.

Here is a quick step by step list of setup details. The full application include KEPServerEX screen shots for easier understanding of ANC-100e setup. https://automation-networks.com/wp-content/uploads/2016/06/ANC120e-ANC100e-KEPWare-Ethernet-IP-to-DH-app-note-2-1.pdf

*Pocket-sized convenience.

*High performance, Industrial Rated Ethernet DH+ Converter.  

*Ease of Configuration via Web Interface

*DH+ Auto Polarity Detection

*DH+ Auto Baud Rate Detection.

The ANC-100e provides all these AN-X2-AB-DHRIO published features too:

*This operating mode acts as a bridge between an EtherNet/IP and a Data Highway Plus network.

*Programming terminals, and/or processors on an EtherNet/IP network can access legacy processors on a DH+ network

*Download to a PLC5 or SLC through RSLinx

*Configures through web browser

*Supports all DH+ baud rates (57.6, 115.2, and 230.4 K baud)

*Support for DH+ to EtherNet/IP PanelViews upgrades on PLC5 or SLC networks
