In LWE use a digital value and then in LOGO! program a digital network input. Edit: To see the status of the soft key in your case, show the status of M2 in LWE.

I have added a programmable switch which enables or disables the time trigger function from the panel level. I also wanted to share this option from www.

A softkey can only be used in a LOGO! display or TDE display or in the simple web server of the LOGO! to be served. A softkey is to be compared with a digital value in the extended web server. You assign the digital value to a flag or a bit in the V-memory. You then query this bit in the V memory as a digital network input in the LOGO! Program.

I was thinking about the pulse relay but it cannot be read and and write from the logo panel. I would like to implement a binary parameter that would be editable from both the panel and website, and save state after restart.

From web server send a V-bit. But the web server make only switch function, not a push button function. But you can make in the LOGO! program the switch function to a push button function by a digital network output with the same address as the input. Then you connect the both outputs (soft key and network input) to a OR block and the output of the OR block connect to the trigger input of a pulse relay. Attachment Untitled.PNG (291 Downloads)

rafalk_26 Posts: 9 Rating: (0)	There remains a problem how the user standing at the panel should know whether it enables or disables the function and how is its status on or off? On the website I can connect network output with the same address to the output on the pulse relay and I have status on or off.
