Title: How To: change contact function
Post by: RBeersJr on May 02, 2017, 07:07:04 PM
The Normally Open contact and the Normally Closed are maintained contacts when using the "Simulated I/O Driver#0"

How do I change operating function from a maintained contact to a momentary contact when using the "Simulated I/O Driver"?

Thank you for any help
Richard

Sorry, I don't understand, what you meant for momentary and maintained contacts???.
Perhaps you mean coil activation by level or trigger???

I shall find an explanation
Maintained simply means that when you push it on it stays on until you push it off and so on. A typical way of seeing a maintained circuit spelled out on many website is such as this: On-Off-On.

Momentary simply means that it is only On (or off) when you are holding it then it spring returns to the maintained position. Think of your car window, usually it only goes up or down when you are holding it and it stops when you let go. This is an example of momentary. A typical way of seeing a momentary circuit spelled out on many website is such as this: (On)-Off. Any time you see the parenthesis symbol around the function it indicates it is momentary.

the Simulated I/O Driver behaves as a Maintained contact or switch. I wish to have the contacts behave as a momentary contact (spring return to original position)
Is this possible? if "yes" how do I do this?

OK! sorry was very clear, I understand.
Then you must to use the VirtualPanel driver, that allows to configure input signal as maintained (switches or pushbuttons with interlock property to true) or momentary (pushbuttons with interlock property to false).

I am unable to locate the virtualpanel driver. In easyplc.
I have searched the pdf manual for reference but I do not find any virtual panel driver.
I discover a function Key ('letter or number') that works.

I am trying to move on to the HMI builder, and learn to link the ladder diagram to the HMI icons.
