FB_ScenesLighting

This function block is intended for the management of lighting scenes. The function block is enabled via the bEnable input. The loading of the saved scenes is started by a positive edge at the bEnable input. The input must remain TRUE until the operation is completed. The values of the scenes are saved non-volatile in the TwinCAT Boot directory as a *.bin file. The last data status is saved in a *.bak file as a backup.

Save scene

The values of the inputs nActualValueLighting_1..14 are saved in the respective scene by a rising edge at the input bSaveScene_1...16.

Load scenes

The saved values are output at the output nDimmValue_1..14 by a rising edge at the input bInvokeScene_1..16. Furthermore, a positive edge is generated at output bSetDimmValue_1..14 for a PLC cycle.

bEnable: enables the function block.

bInvokeScene_1..16: calls the respective scene.

bSaveScene_1..16: saves the current analog value nActualValueLighting_1..14 in the respective scene.

nActualValueLighting_1..14: current control value of the respective lamp. Return value from the dimmer function block FB_Dimmer1Switch().

sFile: file name (without path and file extension) for saving the scenes. The file name must be unique in the entire project. If several instances of the function blocks FB_ScenesLighting() or FB_ScenesVenetianBlind() are created, then each instance must use a different file name. The file is always saved to the TwinCAT Boot directory and is given the extension .bin. Example: 'ControlPanelA'.

nOptions: Reserved for future developments.

bSetDimmValue_1..14: output with the edge for the input bSetDimmValue of the function block FB_Dimmer1Switch().

nDimmValue_1..14: Output with the value for the input nDimmValue of the function block FB_Dimmer1Switch().

bInit: this output goes TRUE as soon as the initialization of the function block is complete.

bError: this output is set to TRUE as soon as an error is detected during execution. The error code is contained in nErrorId.

nErrorId: contains the error code as soon as bError goes TRUE. See Error codes.
