Hi!

I am writing an equation which contains an unknown number so that I can solve
using simultaneous equation.The problem I am having is that I dont know what to insert a function for the unknown number.

Val(1001)+Val(1021)*(x)

whereby x is my unknown number.

How do I do that?

Therefore, the formula cannot be an unknown number. It is either the calculation of other formulas (channel) or a known number.

So how do i use solve simultaneous equation using Scada. Is there like a source code that i can use or anything?

You need to channel to find the value of X knowing Val(1001) and Val(1021) ? Then you need to know the answer

Or do you need to find the value of Y given you the formula, where another unknown ? And mathematics can’t do, not what scada

Channel number 1000 – evaluation X
Then your formula in the channel 1022 – Val(1001)+Val(1021)*Val(1000)
