Hi all, I just wanted to give you an update on my progress on the EtherNet/IP protocol. It turns out that using the “digitalpetri” drivers works like a charm. But it also turns out that implementing a PLC4X adapter with a given driver is not that trivial. Right now I’m reading the EtherNet/IP spec in parallel in order to know what I have to do when, how and in which order. But I’m making quite good progress :-) I did have to issue a Pull-Request for the driver though as one important command was not implemented. Let’s see how fast we are able to get a release with those changes in them.
But one thing I did learn this way, is that even if we lose some of the functionality when not using the native protocol API, it does dramatically simplify writing software for a PLC without understanding the essentials of the protocol used to access the device. Hopefully I’ll manage to get the EtherNet/IP protocol working this week. Chris
