Below I am adjusting part of the second LOGO! Program, but I would like to have the ability to manage the weekly timer and display the temperature (AI2) via the web site, and if possible the temperature settings in block B010 (analog treshold trigger). For the weekly timer, I like the option from this post https://support.industry.siemens.com/tf/ww/en/posts/lwe-how-to-input-time/221270/?page=0&pageSize=10 Attachment 1st floor heating.zip (268 Downloads)

Values that should only be displayed on the extended web server are unproblematic. Values that are to be displayed and changed on the extended web server create problems if the data is sent via a second LOGO! be mapped. Such as the switching times of the weekly timer and switching days. In your case, this data can then only be changed on the extended web server, no longer via the LOGO! or via a TDE display. The same applies to the parameters ON and OFF of the threshold Trigger.

The software automatically takes care of creating a connection. For your desired function, you must manually create a connection between the LOGO!s and enter the data in the associated connection table as well as the correct direction of transmission. The data must be in an area of the VM memory of the first LOGO! which of the first LOGO! is not used, e.g. from VW200.

And how do I copy that to main LOGO! then LWE read it? Can you please give me one practical example?
