Function description

General

This function block serves as a slave function block for a clock system with 32 weekly timers, 30 public holidays, 10 holiday periods and 5 special switch times. It allows the individual activation / deactivation of the 32 weekly timer channels, the public holiday channel, the holiday channel as well as the special switch times channel (FALSE = deactivation, TRUE = activation). The connection between the master function block and the slave function blocks is established via the output itfToClockSlave32 or the inputs itfFromClockMaster32 established. The inputs sTitle or sLine1 allow the specification of the label of the title or line 1 in the visualization.

State of the slave channel xActive

The output xActive (FALSE = not active, TRUE = active) is determined by the current states of the assigned weekly timer channels (xClockCH_01 to xClockCH_32 = TRUE) of the assigned public holiday channel (xPublicHoliday = TRUE), the assigned holiday channel (xHoliday = TRUE) or the assigned special switch times channel (xSwitchTimeS = TRUE) as follows (Note: channels that are not assigned automatically take the state FALSE):

Weekly timer channels	Public holiday channel	Holiday channel	Special switch times channel	Central activation ( Master )	Central deactivation ( Master )	xActive	Notes
FALSE	FALSE	FALSE	FALSE	FALSE	FALSE	FALSE	Normal operation - Off
TRUE	FALSE	FALSE	FALSE	FALSE	FALSE	TRUE	Normal operation - On
X	TRUE	FALSE	FALSE	FALSE	FALSE	FALSE	Public holiday operation - On
X	FALSE	TRUE	FALSE	FALSE	FALSE	FALSE	Holiday operation - On
X	X	X	TRUE	FALSE	FALSE	TRUE	Special switch times operation - On
X	X	X	X	TRUE	FALSE	TRUE	Central activation ( Master )
X	X	X	X	X	TRUE	FALSE	Central deactivation ( Master )

Legend: X = arbitrary

Central cancellation of all assignments xResetAssignment

This setpoint / parameter is used for the central cancellation of all assignments made in the slave function block.

Interfaces Visu-Element

Name	Data type	Type	Initial value	Function
FB_ClockSlave32	ClockSlave32	VAR_IN_OUT		Enter FB ClockSlave32 here e.g. PRG.ClockSlave32
FB_ClockMaster32	ClockMaster32	VAR_IN_OUT		Enter corresponding(!) FB ClockMaster32 here e.g. PRG.ClockMaster32
BMS_Active	BOOL	VAR_INPUT		BMS (Building Management System) GLT (building management control). If BMS_Active = TRUE, the input / editing of the clocks is disabled because they can then only be set via the BMS. Clock times can then only be viewed.

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