FB_DALI103QueryEventFilter

FB_DALI103QueryEventFilter 1:

The function block reads the event filter (see eventFilter) for the selected instance of the DALI control device.

Each bit of the input variable nEventFilter represents an event. If the bit is set, the associated event is enabled.

The meanings of the individual bits for the respective instance types can be found here:

Part 301 (push buttons) – Introduction

Part 302 (absolute input devices) - Introduction

Part 303 (occupancy sensors) - Introduction

Part 304 (light sensors) - Introduction

The output nEventFilter contains a valid value only if the function block was executed without errors (bError = FALSE).

FB_DALI103QueryEventFilter 2:

The function block cannot be used when using the KL6811.

Name

Type

Description

bStart

BOOL

Execution of the DALI commands is triggered via a positive edge at this input.

nAddress

BYTE

Address of a DALI control gear or a DALI group.

eAddressType

E_DALIAddressType

Defines whether the input nAddress contains a short address (0…63) or a group address (0…31). The input nAddress has no meaning if a broadcast or a broadcast to unaddressed devices (BroadcastUnaddr) has been selected.

nInstanceAddress

BYTE

Instance number within a DALI control device. A DALI control device can support multiple instance numbers.

eInstanceAddressType

E_DALIInstanceAddressType

Defines the access mode to the desired instance within the DALI control device.

eCommandPriority

E_DALICommandPriority

Priority (low, middle low, middle, middle high, high) with which the DALI commands are sent.

FB_DALI103QueryEventFilter 4:

The command priorities are supported by the KL6821 from the firmware version BD.

FB_DALI103QueryEventFilter 5: Outputs

VAR_OUTPUT
  bError                  : BOOL;
  ipResultMessage         : I_TcMessage;
  bBusy                   : BOOL;
  nEventFilter            : DWORD;
END_VAR

Name

Type

Description

bError

BOOL

This output is switched to TRUE if an error occurs during the execution. Further information about the error can be queried via the variable ipResultMessage. The output is set to FALSE again as soon as bBusy switches to TRUE.

ipResultMessage

I_TcMessage

Interface pointer (see error evaluation) that can be used to obtain detailed information about the processing of the function block (see runtime messages). The interface pointer is valid after bBusy has changed from TRUE to FALSE.

bBusy

BOOL

The output is set as soon as execution of the DALI commands has commenced. It remains active until all DALI commands have been processed.

nEventFilter

DWORD

Each bit represents a manufacturer-specific event that has been enabled or disabled.
