Hi,

Is there any way to generate a pulse output signal with a frequency higher than 1 Hz using Yokogawa CENTUM CS3000? Maybe some discrete output module (generator?), which receives the specified frequency value as voltage or current?

Thanks.

You have asked a question that i asked myself two months ago. Put your logic chart (LC64) in high speed scan, and then add blocks TON & TOFF in series, in succession. For eg. add five such pairs. Loop the final TOFF output to the very first TON input. You have a good pulse waveform with 20% duty cycle. For developing frequency modulated output, write appropriate logic using calculator blocks for routing the 'proper' TON-TOFF pair output to the final output.

Nice solution, thanks.

I've made this scheme and thought that it's unnecessary to add intermediate TON blocks. Only first block is TON and others are TOFF. Because TOFF and following TON turning on and off together:

1,3,5 - TON; 2,4 - TOFF

What do you think about it?

 

Well... it seems like a good simplification... just ensure that the proper waveform you need is generated.
