CfgRead3DAxisIds
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.
