yet another newbie... apologies

[marc pearson]

Hi all, thanks for add to the group.

I am a software developer, inexperienced with industrial protocols. My work have given me a device, and asked me to communicate with it from within our software base (windows, c# .net).

The device supports EthernetIP, profinet amd diffferent version support Modbus.

I have a memory map for the device, listing addresses for the different registers.

At first I tried setting up a TCP connection and tried some Modbus commands - I did get responses, but with errors....

So, I am looking at using EthernetIP and stumbled across this library. All I am wanting to do is poll certain registers, to get some status updates. I fear that using this library for this task is a bit overkill, so I am hoping for some advice on how to accomplish what I want, given the information I have.

Yours hopefully,

Marc

Hi,

unfortunately OpENer is for the device side and not for the readers side. So you need to find another lib.

BR,
Alois

Hi;

I also need a lib for the scanner side, perhaps you know a free one.

It would be very helpful.

Thanks

For the scanner side I use this one: https://github.com/rossmann-engineering/EEIP.NET

It's .Net/C# but a good resource for implementation specifics.

Sorry,

I forgot to mention that is a Linux C/C++ project.

The Linux part might be addressable by .Net Core but I don't know of a recent open-source C/C++ scanner implementation, would love to know if there is one.
