How to enter Time of Day

[Mvlawn]

I would like to write the time of day, I want something to happen. What should I use for this?

Write time of day on a form? or in the PLC?

[Mvlawn]

Sorry for the lack of clarity. I am looking to move the time from the HMI/Form, to the PLC. I am currently using the keypad from a DigitalPanel meter and writing that to floating register. I then dived by 100 so the minutes and hours are separated by a decimal, then copy that to an integer, and use a little more math. this separates the hours and minutes for me into different registers. I assume an easier way exist.

This is how I would do it:

- Add a button to the form
- Double click the button to get back to the code
- Enter this code:

Code: [Select]

ModbusTCPCom1.Write("40001",Now.Hour)
ModbusTCPCom1.Write("40002",Now.Minute)

Just change according to the driver you are using and the registers that you need to write to.

Hi,
Can this code you provided above:

ModbusTCPCom1.Write("40001",Now.Hour)
ModbusTCPCom1.Write("40002",Now.Minute)

be used as a substitute for a rtc. Instead of a button press the time would be written automatically every time Advanced Hmi updates.
I don't need any great accuracy just minute and hour.

- Add a Timer from the All Windows Forms group in the Toolbox
- Set Interval to 60000
- Set Enabled to True
- Double click the timer to get back to the code
- Enter the above code
