PC to CP1L-E Fins over TCP

[CFK 0]

So I've been having an issue for a few days now. 

When creating a Python script I can communicate to a CP1L-E trough the FINS protocol without issue. Now I'm trying with a different device that can speak TCP/IP native but I seem to been having some issues.

 

When quarring DM100 for example the response I'm getting is 2 bytes short:

Sending: 16#46/49/4E/53/00/00/00/1A/00/00/00/02/00/00/00/00/80/00/02/00/01/00/00/FB/00/01/01/01/82/00/64/00/00/01

Receiving: 16#46/49/4E/53/00/00/00/16/00/00/00/02/00/00/00/00/C0/00/02/00/FB/00/00/01/00/01/01/01

After this response I'm bombarded with error codes that don't seem to be documented by Omron at all. I need to establish the connection again to get a new response.

What I expect is getting a size of 16#18 and my expected response added to the packet.

 

Weird thing is, when establishing the connection I have no problem. The PLC response the Destination Node Number (16#FB) without questions. But when quarring the DM it doesn't seem willing.

 

Is there an expert on the matter that can help an old dog that's trying a new trick?

 

Thanks in advance. If you need any info, please don't hesitate to ask.
