labVIEW code running control using Timer

[Austyno]

I have a LabVIEW code which needs to be timer control in terms of code running. The code should work as follows?

1. Need a timer that resets every 60 seconds.

2. From 0-30 seconds, the code should write the value 0(zero) to Modbus register 9 of slave device address 5

3. from 31 - 60 seconds, the code will write the value 256 to same Modbus register 9 of slave device address 5.

4. The timer will reset to zero  and this loop continues for every 60 seconds.

Does anyone in the forum got an idea or a typical LabVIEW code that can perform the above function?

Put what you want in the case structure.

Can you please send me the VI?

It is a snippet, if your have LabVIEW 2018 you should be able to download it and drag it to the block diagram and it will run. Note the code it meant to be in a loop.

What version do you have?

I have 2017 version

Loop Example in LabVIEW 2017 attached. You may have to play with the rounding to get it just the way you want it.

Thanks. will try it out.

I would just use the Elapsed Time VI in the Timing palette.  It can everything but the case structure for you.

Never used it before, good catch.
