The I/O Tasks
Now the I/O task(s) must be added. Up to 5 tasks are available. In the property page on the left side enter a port number from 301 (task 1) to 305 (task 5). Please ensure that the "Auto-Start" check box is left unchecked. In this example the real time tasks are not running, only their process images are used. Detailed information about Additional Tasks are available under TwinCAT System Manager - Addtional Tasks.
