sample & hold in PCS 7

Paulvdbo

Any one can help me to make a "sample & hold" circuit ?
At a certain moment/event I want to display an anologue value and leave it on the display until the next event, the new value will be displayed until the next event etc ...

thanks in advance !

Hi,

here an example. Shouldwork with a LOGO! 0BA6&0BA7.

You can use the math instruction to store an analog value till the next trigger.

Hope this heps
