I/O
Function: Using TwinCAT 3 I/O, cyclic data can be collected by different fieldbuses in process images. Cyclic tasks drive the corresponding fieldbuses. Various fieldbuses can be operated with different cycle times on one CPU. Applications can directly access the process image. The fieldbuses and the process images are configured in TwinCAT 3 Engineering.
Call: Click on the arrow in front of I/O.

Online Change… | Online Change of mapping information is performed |
 | An Online Change of the mapping changes the copy rule of the data. The Online Change can only be performed if the process images themselves do not change. Changing process images always requires reactivating the configuration. An exception to this is the process image of a PLC. |
