Hi guys, what is the best method or protocol to connect a Red Lion Data Station to Ignition? I want to transfer information to Data Station (Marquee) from Ignition Database.
thx

I reckon the most straightforward way would be over Modbus TCP. You could set up a number of SQLTags which write their values to registers in the Data Station Plus and update these SQLTags with data from Ignition using a script. The Data Station Plus would then read these registers as normal tag inputs.
I’m not too familiar with Red Lion Data Stations, but if it does support being connected to via Modbus TCP then AlThePal’s advice sounds good to me. Although I would suggest trying out a transaction group before going with a script, especially if you have a lot of data points to transfer at once.
If you’re not familiar with Transaction Groups, you can find more information here:
