TC1701 | TwinCAT 3 Usermode Runtime: External Control

The TwinCAT 3 Usermode Runtime provides a way to run the applications programmed in TwinCAT without real-time properties in the user mode of the operating system. The TwinCAT 3 Usermode Runtime can be used free of license costs purely for engineering purposes and only requires (trial) licenses of the TwinCAT products used.

The “External Control” option – which is subject to license costs – provides an interface that runs the application, clocked by an external application. This is created by the customer through an API and thus controls the execution.

An interface is available for the application to use the “External Control” option and to be able to change it during the run. Synchronization with other programs can be achieved with this option.
