Hi
I actually need a script that toggles between 0 and 1 at specific times during the day.
I did some search and came across the following script:

double ToggleAtSpecificTimes(DateTime currentTime)
{
DateTime[] toggleTimes = new DateTime[]
{
new DateTime(currentTime.Year, currentTime.Month, currentTime.Day, 8, 0, 0), // 08:00 AM
new DateTime(currentTime.Year, currentTime.Month, currentTime.Day, 12, 0, 0), // 12:00 PM
new DateTime(currentTime.Year, currentTime.Month, currentTime.Day, 18, 0, 0), // 06:00 PM
new DateTime(currentTime.Year, currentTime.Month, currentTime.Day, 22, 0, 0) // 10:00 PM
};
{
if (currentTime.Hour == toggleTime.Hour && currentTime.Minute == toggleTime.Minute)
{
return 1; // Return 1 at the specified times
}
}
return 0; // Default to 0 at all other times
}

I copied the above in the Scripts table and Rapidscada worked without any issues.
However when I added a Channel and in formula used ToggleAtSpecificTimes(DateTime.Now), Rapidscada stopped working.

Please guide

Thank you in advance

Hi

Just one more guidance.

If a channel is required which should return 0 or 1 at specific time say 6, 8, 10, 12, 14, 16, 18 and 20 hours, what would the script be ?

Appreciate your help and assistance

The solution works.
Many thanks for the guidance.

Hi
I picked up if(hour()… from google search.

From the record I would like an output of 0 or 1 to be able to access from multipoint trigger in automatic control module.

Basically i would like to create a channel that can be 0 or 1 depending on the time, and use it in a multichannel trigger.

Please guide

Thank you in advance

Hi

I tried creating a calculated channel with following formula and Rapid Scada stopped working:

if(hour() >= 8 && hour() < 20, 1, 0)

Please advise

Thanks

[rapidscadaaks]

Thanks for the tip. Please advise how to use data of 2 channels for returning 1 or 0

Many thanks in advance

[rapidscadaaks]

This scenario is better. Please advise how to create a channel that can be 0 or 1 depending on time.

Thanks in advance

Hi
Manufacturer (Waveshare) is not responding to the issue.
I have checked connecting the device directly to the PC using serial port and values are not received for the Input Channels. The issue therefore is not Rapidscada related.
I am therefore using alternate product and results are fine.
Thank you for the assistance

Hi
I tried polling one register from 0 using Holding Registers and there was no response from the unit

I have created a support ticket with the manufacturer and await their response.

In the meantime, please suggest software for testing purposes for sending command to the unit and getting response.

Hi
Awaiting guidance for resolution.
Thanks

[rapidscadaaks]

Yes. This matches with the documentation.
