FB_DALIV2Initialise

FB_DALIV2Initialise 1:

The function block FB_DALIV2Initialise is used to start the addressing of the control gears. The addressing has to be terminated again with the function block FB_DALIV2Terminate. The maximum duration is limited to 15 minutes. Each control gear ends addressing automatically after 15 minutes. The reaction of the control gears that receive this command depends on the parameter nParameter:

Value (binary)

Description

0000 0000

All control gears respond.

0AAA AAA1

Control gears with the address AAA AAA respond.

1111 1111

Control gears with no short address respond.

stCommandBuffer

ST_DALIV2CommandBuffer

Reference to the internal structure for communication with FB_KL6811Communication (KL6811) or FB_KL6821Communication (KL6821).

FB_DALIV2Initialise 4: Outputs

VAR_OUTPUT
  bBusy    : BOOL;
  bError   : BOOL;
  nErrorId : UDINT;
END_VAR

Name

Type

Description

bBusy

BOOL

When the function block is activated the output is set, and it remains active until execution of the command has been completed.

bError

BOOL

This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in nErrorId. Is reset to FALSE by the execution of a command at the inputs.

nErrorId

UDINT

Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs (see error codes).
