OMRON FINS TCP documentation

Hi Guys,

a few years ago I started to write a little test program for PC to communicate with OMRON PLCs by FINS commands. Well, I would swear there was a really nice documentation about this, but I cannot find it. Maybe it was this: https://www.support-omron.fr/telech...Z909-E1-01 CS_CJ EIP21 Ethernet IP Units .pdf

I think Section 7 is what I need. But - as you can see - this document should be at least 163 pages long, but it is only 77 pages. (????) So there is no Section 7 in it.

Does anyone has this documentation? Or any DETAILED information about FINS/TCP FINS/UDP? (I find this page: https://flat2010.github.io/2020/02/23/Omron-Fins协议/#comments but there some really important information is still missing here)

Take a look at the W342 manual.

Well, meanwhile I found what I needed. It was the OMRON W421-E1-03 Ethernet Communication of Applications Operation Manual.

(The most important thing what I was looking for is at pages 186 - 191. There is a small C program example for FINS/TCP communication. Using this, I could finish my test program.)
