How can I do an hour schedule on LOGO8?

  Hello,

  I'm using LOGO8 with an hmi by ethernet. I need to do an hour schedule setted by user on hmi, selecting an hour to start an memory and an hour to stop, on the image you can see this by NI1 and NI2. How can I do this logic?

I don't see NI1 and NI2, only NAI1 and NAI2. Mean you this two? 

The problem is that you not have a direct access to time and date of the real time clock of the LOGO!.

For this is normally the block Weekly Timer. But the switching times are formatted in BCD code.

Or you make your own counter that counts up 1 at every hour.

Here's a example.

But not:

The logic can only work correct the day after the new start of the LOGO!.

Oh sorry, i means NAI1 and NAI2, because de hmi is sending an analogic signal (1 to 24 ). I'm using an kinco hmi

 1-24? In my eyes not correct. I mean 0-23.

The format of the value of the counter is a double integer.

If you take a look at Parameter-VM-Mapping (under Tools) then see you that the counter value is transferred to the VM memory to VD4. VD4 = VW4 + VW6.

Counter values lesser then 32,768 are in the right word, VW6. So it's possible to read back to counter value to the logic.
