Description

This function opens the faceplate of a symbol.

By default this function is first checked to see whether a license for the library is available. The library HOOK-function hook_<LibName>_libLicenseAvailable() is called. Furthermore the entry of the config entry faceplateModal is checked. Depending on the set entry, the faceplate is opened modally or not modally.

You can find the function in the stdlib_hook_project.ctl under wincc_oa_path/Stdlib_3.20/scripts/libs/
