Link a PLC to an axis object
- An axis object has been created;
see Create an axis object. - A PLC project containing an instance of Tc3_Mc3Ptp.AXIS_REF has been created.
- 1. Build the PLC project.
- The
axis instance of the Tc3_Mc3Ptp.AXIS_REF should now be displayed under the PLC instances in the Solution Explorer tree.

- 2. Link the PLC instance of the
Tc3_Mc3Ptp.AXIS_REF to the MC3 axis instance (steps 1–5).

- The axis is now linked to the PLC.
- The text field next to the Link to PLC… button displays the linked instance of AXIS_REF in the PLC.
- In the configuration tree in Solution Explorer, a linked variable from the cyclic interface is indicated by a blue or white icon.
