3000 Tags is not too little, only very big machines or the monitoring of more than the TBM (belt conveyor, power generator etc.) will normally break the barrier of 3000 data tags. And yes, you are right, a "tag" in that definition equals one physical or virtual sensor, which generates a signal.

Though, Leif had answered before, that downloading and testing is for free, but the utilization not anymore. Also, I saw on their website that they charge, if you want to use it with an InfluxDB (a timeseries database). InfluxDB itself is also free to use (as of my last information a while ago ... maybe they have changed their pricing model also), but it strikes me, that they charge for something that is free to get on the market? But ... of course, they also need a monetization strategy.

Hi

A quick reply is It is ONE input to the Open*Plant system i.e one sensor on the TBM.

3000 would be sufficient for 1 TBM.
