HI I have buit a program which allows the connection of pushbuttons using LWE, however i can not get the LWE when i run it on the web interface to control the pushbuttons.

I am trying for example to switch on I20 i can not enable Block type I and then 20 then i can not make it writeable. I tried using the internal relay in the device M20 and although i can make this writeable it still makes no difference.

What am i doing wrong I can read the analogues no problem and the setpoints 

As a note: i can only use edge to view the program or display from the web editor when i hover over the button i get a No Entry appear .

I have now noticed that within the LWE when assigning the tags i noticed now i have Variable 1 etc.. available which is now linked to the I 20 input but no change it will still not let me modify the button on the web page?

Hi Buttsy26

There is no make sense write the I20, this is the reason the writable checkbox is hide.

You can read the status of I20 without problem.

To switch the I20 you do need to have some sensor/digital input phisically.

Hope it helps.

Inputs such as I20 cannot be set via the LWE, only the status can be queried !

This also applies to markers, provided their control is assigned. If you want to switch or touch markers from the LWE, its input must not be assigned in the logo program !

Hi Ella soon a new year will be here, Thanks i wasn't aware of this and i wish i had asked earlier as i spent a couple of hours trying to figure this out. I have written the program in ladder so i will need to figure out how i add a way to control this via LWE.

Thanks as always Paul
