CfgRead3DAxisIds

CfgRead3DAxisIds 1:

The function block CfgRead3DAxisIds reads the axis configuration of a 3D group.

VAR_INPUT

VAR_INPUT
    bExecute       : BOOL;
    nGroupId       : UDINT;
    pAddr          : PVOID;
    tTimeOut       : TIME;
END_VAR

bExecute: The command is triggered by a rising edge at this input.

nGroupId: ID of the 3D group

pAddr: Address of the variable into which the function block writes the axis IDs of the group assignment (array with three elements of type UDINT)

tTimeOut: ADS Timeout-Delay

VAR_OUTPUT

VAR_OUTPUT
    bBusy     : BOOL;
    bErr      : BOOL;
    nErrId    : UDINT;
END_VAR

bBusy: This output remains TRUE until the function block has executed a command, but at the longest for the duration supplied to the 'Timeout' input. While Busy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.

bErr: 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 ‘nErrId’. Is reset to FALSE by the execution of a command at the inputs.

nErrId: 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. The error numbers in ErrId can be looked up in the ADS error documentation or in the NC error documentation (error codes above 0x4000).

Sample:

VAR
    (* instance *)
    ReadAxIds : CfgRead3DAxisIds;
    AxIds : ARRAY[1..3] OF UDINT;
END_VAR
ReadAxIds( bExecute := TRUE,
    nGroupId := 4,
    pAddr := ADR( AxIds ),
    tTimeOut := T#1s );

AxIds now contains the three axis IDs for the 3D group with the group ID 4.
