How to send Clock Pulse of 2s using the Special Clock Pulse bit
« on: November 10, 2022, 11:22:45 PM »
Hi! A bit new to TriPLC. This may be a simple question but how do I trigger a coil every 2s using the Special bit Clock pulse?

There isn't a Special Clock Pulse bit with a period of 2 seconds.

But there is a 1 second period clock named "Clk:1.0s.

You can use a COUNTER to generate a 2 second clock from Clk:1.0s

The trick is to make the COUTNER count up with the use of special function coil, [UpCntr].

A COUNTER with a set value of 1 will count 0,1,0,1... as an up-counter. The contact for the COUTNER will be active on the "0" count time period.

I have attached a screen shot of of the ladder logic to get this to happen.

Good luck,
