Delay Vs Timer

Would like to know how much processing power a delay in logic uses?

Be good to compare it to a timer running.

Thanks.

 

My understanding is that a delay stops the logic processor at the delay line for the delay period, where as a timer works in the background of the logic engine..

 

When you use a timer you need to keep testing it so the module is being continuously run (every 200mS anyway) and your logic code is being continuously executed. With a delay the whole module stops and no logic code is executed so the delay will be more efficient. The logic engine will perform the delay testing internally, but since it's running compiled code and not interpreted code it will do it much faster.

This all depends of course on how the logic engine is implemented so you will need confirmation from the guy who wrote it, but that's how it would work if I wrote it

 

Great thanks.

Good to know its just that module. Is the time close to accurate delay "00:05:00" is pretty close to 5 minutes in the touch screen/PAC?

 

Given that the modules are run every 200mS that will be the determining factor in the accuracy of the timers or delays
