IO Configuration

The I/O - Configuration is an important component of the TwinCAT System Manager. The lowest level of TwinCAT is TwinCAT Level I/O, means an I/O Configuration entry in the TwinCAT System Manager tree- view is always present. After the various Configurations have been executed for the different tasks and the System Manager has been acquainted with all relevant variables, the hardware (usually a fieldbus with I/O modules) is configured under this rubric. It is also possible to configure the I/O section first and the other tasks (e.g. PLC tasks) later on, of course.
