Function description

General

This function block determines whether a public holiday is active and displays the name for that holiday. The function block must be enabled via the input xEn to be activated (TRUE = function active). The public holidays can be defined via the structure stPublicHoliday. Here the name, the date of the holiday and the enable status are specified. Holidays can be defined as a fixed date, with an offset to Easter or a weekday before a fixed date. The setpoint / parameter eCountry allows the specification of the country whose holidays should be used. Currently only the holidays for Germany are implemented.

Name	Data type	Type	Initial value	Function
FB_PublicHoliday	PublicHoliday	VAR_IN_OUT		Enter FB PublicHoliday here e.g. PRG.PublicHoliday
BMS_Active	BOOL	VAR_INPUT		BMS (Building Management System) GLT (building management). If BMS_Active = TRUE the input / editing of the clocks is disabled because they can then only be set via the BMS. Times can then only be viewed.
DisableInput	BOOL	VAR_INPUT		DisableInput = TRUE Times of the weekly clocks can only be viewed and not edited. /// - BMS (Building Management System) GLT (Building control technology). If BMS_Active = TRUE the input/editing of the clocks is disabled because they can then only be set via the BMS. Times can then only be viewed.

Note: VAR_IN_OUT interfaces must be assigned, VAR_INPUT are optional.
