Use web server input as Network input

Attached is a picture of how I achieved control of a function via web server. This setting available via both Logo front panel display/keys and via web server is to enable "holiday mode" for a system, where it just keeps the tanks & pipes warm, but doesn't do any production control, for when the operator is on holiday.

First you add a soft key to your Logo FBD and connect the output of that to anything that needs to be changed when the soft key is on. 1st bit of picture.

You then create a Message Text with the soft key as a block in the text. Make sure protection is not active and the web server box is ticked. Middle picture.

When message test is displayed it is edittable on both local display and web server. Final picture.

Works well especially when someone forgets to put it in holiday mode, one can log on remotely and engage holiday mode.

Thank you for the Answers...
Actually I am Embedded engineer and I don't know any thing about LOGO programming and I wanted to control the home appliances via phone or PC, that is why  I asked the question.
