Hi Mikhail

Can you please guide how to setup a channel to show a command dialog that contains several buttons with command values ?

Thanks

Hi Mikhail

This works. Thanks.

I have a last follow up question on the subject for understanding :

What is the difference between following the above solution (making a script for a function and calling the function in an output channel) and just using SetData() in an Output/Calculated Channel (as suggested by you in another topic) ?

Thanks for all the help

Hi Mikhail,

This works.

Thanks for the help.

Hi Mikhail

I tried and it did not update the input channel value.
As suggested, I entered the function in output type channel in output formula. This output channel is not connected to any real device.
Server log mentions command queued for sending to clients.
Please help
Thanks

Hi Mikhail

I actually have 2 tasks :

1. First is when sending command to a device using output channel to change colout of LED in Schema
2. Second is to enter value of a calculated / input using Schema. Since this cannot be done directly, value for the input channel is to be updated to a output channel which is not connected to any device which in turn updates an input / calculated channel.

I hope my above explanation is adequate

Thanks

Hi

Please advise to change input channel value using :

1. Command sent to a device
2. Command sent to an output channel which is not attached to any specific device but only for getting value for updating input channel

Thanks

Hi

I found the answer. Add command after the first with a delay.

Noted Mikhail.

Thanks

Thanks Mikhail for your revert which is extremely helpful.
Just one question : what is the difference between using Cnl(101) and Val(101) ?

[rapidscadaaks]

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;
}

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

Thanks for the clarification. Just one last question : if there are 3 channels to be checked, they will be chn1, chn2 and chn3. Will chn12 remain chn12 ?

[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
