Creating a PLC project and integrating PLC libraries

Start TwinCAT XAE.

1. A wizard opens with File > New > Project. In this window you select TwinCAT Project and the TwinCAT XAE Project template.

2. Go to the PLC node in the Solution Explorer and select Add New Item from the context menu. Select a Standard PLC Project in the wizard.

3. In addition to the automatically created MAIN, add another programming block. Go to the POU folder and from there via the context menu to Add POU. Select the type Program and call it P_MAIN_LowSpeed.

4. Add another program block and name it P_SerialComm_HighSpeed.

5. Configure 2 tasks in the task configuration under System: a fast one (T#1ms) and a slow one (T#10ms). Assign the program block P_MAIN_HighSpeed to the fast task and the P_MAIN_LowSpeed to the slow task (see figure).
