The purpose of this technical note is to describe the options for integrating Allen-Bradley PLCs using Channel 0 via 1761-Net-ENI Ethernet IP Interface with DeltaV.
A proven solution for the integration of older A-B PLCs like PLC5s and SLC is the use of MYNAH's IOD-1123, Allen Bradley DF1 Driver for the DeltaV Serial Card. Customers who want to link this driver directly to Channel 0 of Allen-Bradley PLCs over a long ethernet link need to use a bridge, an excelent example is two of the A-B 1761 NET-ENI or NET-ENIw modules. We have tested the NET-ENI and NET-ENIw in our labs at MYNAH. There is a faster, more compact offering that should provide an excellent alternative to this configuration utilizing our IOD-4102 Ethernet IP Virtual I/O Module to A-B PLCs via NET-ENI. A product data sheet for the NET-ENI / NET-ENIw can be found on the Rockwell Website as well as the NET-ENI Utility.
Troubleshooting If DeltaV Diagnostics show "No Response" on configured dataset, please double check all of the settings and make sure that the connection to the Allen-Bradley PLC Channel 0 is configured per the Allen-Bradley DF1 Simplex Driver Series 2 Manual>
