Mitsubishi ST-Lite (STL-ETH1) communicate to Q-PLC (Q03UDE)

[JanHrust 7]

Hi. I have a ST-Lite Ethernet base (STL-ETH1) with 1 16 bit digital in card, 3 digital out cards, 2 analog in and 2 analog out cards. I have a Q03UDE CPU (Q PLC) with 1 16bit digital in and 1 digital out card. Now I like to setup the remote I/O (STL-ETH1) mapped to the Q PLC via the ethernet port on the CPU. Is it possible not to use Modbus at all. I don't want to go and buy a Modbus Ethernet card now. Have someone done this before?

The built in Ethernet port on the Q03UDE CPU can be used for Modbus TCP communication with the STL-ETH1 communication node. Mitsubishi should have some nice function blocks for this on their website.

Thanks. Also checked the documentation and it states you can do it, but then asked Mitsubishi Europe and they told me there is no other way, but the Modbus way to do this. Seems like they need to review and update their documentation.
