Calculated Channel computing current minimum value of multiple channels

[rapidscadaaks]

Hi

Please assist for making a formula to calculate minimum value of current date of several channels.

I excel, one would have used min(aa:xx)

Thanks in advance

Hi

I used formula below in a calculated channel and it did not work:

Min(Val(1601),Val(1602),Val(1603))

Server returned following error:

2025-09-08 09:16:30 [SCADA][SCADA$][ERR] Error compiling the source code of the scripts and formulas:
(929,53): error CS1501: No overload for method ‘Min’ takes 3 arguments
Check the source code in Z:\SCADA\ScadaServer\Log\CalcEngine.cs
2025-09-08 09:16:30 [SCADA][SCADA$][ERR] Normal execution is impossible

Please help

Thanks in advance

Found a solution by using following script

public double GetMinValue(params int[] channelNumbers)
{
if (channelNumbers == null || channelNumbers.Length == 0)
return double.NaN;

double minVal = double.MaxValue;

foreach (int cnlNum in channelNumbers)
{
minVal = Math.Min(minVal, Val(cnlNum));
}

return minVal;
}
