Hey guys,
Part of the project I'm working on currently is a remote RTU system that is made by Data-Linc; the remote RTU is a CIX-6430 and the master is a CIX-6435. There's only one single remote RTU, so it's pretty simple. The remote RTU has two analog inputs from level transmitters and simply passes a raw value up to the master via spread spectrum (900 MHz) radio. What I'm trying to do is get my RX3i to communicate with the master via ModbusTCP.
After having issues in the field that we thought might be radio path related, I grabbed the two units and put them on my bench, connected via attenuator so that radio path uncertainty was eliminated. Once I got the radios properly configured, I tried using a program on my laptop to poll the remote site via the master. Wasn't working via ModbusTCP, but when I switch to ModbusRTU and connect to the master via serial cable instead of ethernet, it works exactly as intended. I've tried ModbusTCP with qModMaster and SimplyModbus, both throw errors.
I'm talking with tech support but thought I'd ask and see if anyone here has tangled with these devices before.
