easy way for one shot ?
« on: August 10, 2003, 07:17:35 AM »
One of the missing features in Trilogy is a PULSEOUT command. Is there a simple way to implement a ONE SHOT timer ? I have got a solution with two timers but it is very complicated.
What I want to is set an OUTPUT for a specified number of seconds and then it should shut. The ONE SHOT should only repeat when the trigger relay changes state again.

This is really easy to implement in ladder logic. A screen shot of the circuit is as follow:



You can download the "oneshot.pc5" from the following link:

If you want the oneshot output to turn OFF after the preset timer regardless of the logic level of input1, then you can connect input1 to a [DIFU] relay and use the relay to [Latch] the output. The output will only be latch again when input1 goes OFF and then ON again.
