I am trying to put together a fairly simple HMI for calibrating turbine flow meters and potentially pressure cells. I was wondering if you can use the setpoint box in RTMC to change a multiplier and offset that is programmed in Edlog or CRBasic. I am running mostly CR7s but I also have a few CR1000s and a CR23 with Loggernet 3.1. I am trying to keep things as simple as I can for the operators and I would rather them not playing in the program.
Most controls in RTMC support mathematical expressions for their fields. For instance, if I have a table named one_hour on station "stat" and it has a field named temp_degc, I can enter an expression to convert this to degrees Fahrenheit as follows:
1.8 * "stat.one_hour.temp_degc" + 32
The help should describe all of the expression capabilities that are available.
