Post by jbcregen on Accessing parameters from a structure or function block with the web interface ^{CODESYS Forge talk (Post)}
I have a project with hundreds of OPC-UA variables available on the network. A lot of these variables are used actively in various scripts that run in background in the OS (Linux). I'm experimenting with Automation Server and I have a hard time understanding how the web interface populates its parameters list for a given PLC (<plc details="" parameters="" for="" plc="" 'xyz'="">).</plc> In this page, it looks like the only variables available are the ones that are of a "base" type : bool, TIME, String, INT, etc. All the variables that are nested into function blocks or structures are not available in the web interface, even if they are available to any OPC-UA client. Is this a limitation of the Automation Server or is there something that can be done in Codesys?

Post by ameba on PersistentVars and Webvisu Element ^{CODESYS Forge talk (Post)}
hello everyone I would like to try to better understand how persistent variables work. I created some boolean variables in the PersistentVars section initialized to the value TRUE. I have tied these boolean variables to toggle switches placed inside the HMI interface pages. Once the PLC program is started, the lever selectors, if operated, change their state, at least at a graphical level, but the persistent variables do not undergo any variation. Initially the above variables were declared as simple global variables, in this case the operation with the levers was correct; I then tried to transform them into persistent ones with the aim of using them as "settings saver" Thank you for support Bye
