Connect C# with Sysmac CJ1M-CPU12

[Qbk]

I am new to PLC Omron Sysmac CJ1M-CPU12. Now I want to develop C# software to connect to it. Is there any library I can use to do that? If yes, where can I download it?

Have a look for details on FINS - that is what people use to connect to Omron.

I don't know of a library for any language. But, I never searched for one.

The FINS protocol for CJ1M is CS/CJ and the document is Cat. No. W342-E1-09.

A copy is on this site:

I want to connect to PLC via HostLink RS232C. As far as I know there is OmronPlcCommDotNetLib library but not sure if it can connect? Because I downloaded it but it has many errors and can not be used yet.

The FINS protocol can be used over RS-232C. 

Perhaps you are not interested in reading about about FINS and Host link for the CJ1M CPU.
The protocol specification referenced above might provide you with good information.

I just looked at OmronPlcCommDotNetLib on GitHub. It has not been touched in 2 years.
