This function block adds an axis to a group.
From V3.1.10.1, stationary axes can be added to and removed from a CA group in the GroupMoving group state. If a moving axis is added to a group, the command is rejected with an error message (a change of the group state with a moving axis is also rejected). |
Only axes in GroupDisabled or GroupErrorDisabled state can be added to a MC group. |
VAR_INPUT
VAR_INPUT
Execute : BOOL;
IdentInGroup : IDENT_IN_GROUP_REF;
END_VAR
Name | Type | Description |
---|---|---|
Execute | BOOL | The command is triggered by a rising edge at this input. |
IdentInGroup | IDENT_IN_GROUP_REF | Defines the interpretation of the axis to be added to the group. For multi-dimensional motions, this can be the Cartesian interpretation. The global variables (e.g. MCS_X) must be used. For Collision Avoidance the function UDINT_TO_IDENTINGROUP must be used. |
VAR_IN_OUT

AxesGroup : AXES_GROUP_REF;
Axis : AXIS_REF;
END_VAR
Name | Type | Description |
---|---|---|
AxesGroup | AXES_GROUP_REF | Reference to a group of axes (see Cyclic Group Interface). |
Axis | AXIS_REF | Reference to an axis (see AXIS_REF). |
VAR_OUTPUT
VAR_OUTPUT
Done : BOOL;
Busy : BOOL;
Error : BOOL;
ErrorId : UDINT;
END_VAR
Name | Type | Description |
---|---|---|
Done | BOOL | This output becomes TRUE when the command was successfully executed. |
Busy | BOOL | This output becomes TRUE when the command is started with Execute and remains so as long as the function block executes the command. If Busy becomes FALSE again, the function block is ready for a new command. At the same time one of the outputs Done, CommandAborted (if available) or Error is set. |
Error | BOOL | This output becomes TRUE if an error has occurred during command execution. |
ErrorId | UDINT | Contains the command-specific error code of the last executed command. Details of the error code can be found in the ADS error documentation or in the NC error documentation (error codes 0x4nnn and 0x8nnn). |
