I recommend to create input channels to show current values of hour and minute variables in order to control them.

[Mikhail]

Apparently the calculated channel data never appears correctly in the Scada Comm device data which I was using to check the data changes. It only appears in Scada Web.

Definitely 🙂

Now how can I send the hour and minute parameters from the output channel to my flag channel ?

Add the variables into Formulas table:

int hour = 0;
int minute = 0;

Add the code into Formulas table:

double SetHour()
{
  hour = (int)CmdVal;
  return double.NaN;
}

Use the above formula for an output channel.
Note: I don’t test code which I write in this forum. It’s just a direction for experiments.

It’s strange. Did you pass the changes to Server and restart Server service?
Try simplifying the formula of an input channel.
First of all, try the formula: 1
Then try: DateTime.Now.Minute

Send me, please, an email request for price estimation. Also attach full description of the communication protocol.

You need to develop by yourself or purchase development of a device driver.
Read Device Drivers Development
Source code examples are here

[Mikhail]

What communication protocol is supported by the device?

[Mikhail]

I didn’t write: you have to change channel type to Calculated real.

[Mikhail]

I mean that you should enter the whole CheckTime() function in Formulas table. Then enter just CheckTime() in Input channels table.

[Mikhail]

The simple formula example:

double CheckTime()
{
  DateTime nowDT = DateTime.Now;
  return nowDT.Hour == 1 && nowDT.Minute == 0 ? 1 : 0;
}

[Mikhail]

In formulas you can use DateTime and TimeSpan

[Mikhail]

Do you need a special time for sending command or just a period of doing it?
How accurately you need to define a time? Is it enough to set hour only or hour and minutes?

[Mikhail]

In this case you should use another approach:
Create an input channel as a flag and check time in the channel’s formula. Then create a trigger that fires on the flag value.
To change the timer counter according to a command you need an output channel.

Hello,

Please describe your task in details. Why do you need it?

[Mikhail]

10 min after start Server service. What is in the module log?

The default password is 12345. Try to enter it and look 🙂
