Hello, I am attempting to connect a single SLC504 up to Ethernet in a way that connections can be made from Ignition’s drivers to the SLC directly. Knowing that the 1761-NET-ENI is no longer available, I see that Prosoft offers a product that looks like it’ll work, however looking for any actual experience with the specific product and Ignition. [https://www.prosoft-technology.com/Products/Gateways/PLX5x/DF1-Routing-Module](https://www.prosoft-technology.com/Products/Gateways/PLX5x/DF1-Routing-Module) I’ve also seen posts referencing the Digi IAP, however I’m not sure how that differs from the module in question. Can anyone elaborate? Pros/cons between these two solutions? Finally, the SLC does have the DH+ port open as well, and that could be an option if required. Appreciate any insight that can be provided. Thanks. ---

I recommend a 4-slot ControlLogix chassis (processor not required) with a 1756-DHRIO and a 1756-EN2T (or similar). You’ll have full speed communications over DH+ (even the 230k mode) and the gear can be configured to allow messaging with modern processors (originating in either direction).
