Blinking image

[navigatoru]

Hi, 

 

There is any option in Visilogic to have a image blinking when an MB is 1? Basically I need to have a led that blinks when an operation is running.

 

Cheers, 

Marius

Hi Marius,

You can easily create a blinking led by using SB3 as your contact. SB3 is a 1 sec pulse generator.

Use SB3 to control a toggle bit, then use the toggle bit on your display to control a binary image.

Hi Eyal, 

 

Thanks for reply. The SB3 is doing exactly what I need.

But still I have an issue. 

 

I need something like:

If O1=1 Then 

    MB1 = SB3

End If

 

and in the HMI I can assign the image (that I want to blink) to the MB1 (which will blink when O1=1) 

 

Not sure how to transfer this from structured text to ladder  ... 

 

Thanks for help,

Marius

Hi cantcliff,

 

Thanks for reply. I am not too familiar with ladder. Could you please put a small example?

Having browser issues with images at the moment.

 

For your ladder you need a line like this

 

| SB3 | --- | MB1 | --- ( MB2 )

 

Make MB one the controlling bit that determines if you want your flash.  As long as MB1 and SB3 are close, MB2 is on.  So as MB3 cycles, MB2 will cycle on and off.

 

On the interface design, create a binary Image, one image and set an off image state and an on image state, then link it to MB2.

Sorry for the double post, just managed to get images working.

 

Here's my example as above in picture format.
