Technical introduction

The TwinCAT 3 Usermode Runtime executes an engineering program as the same binary - but not under the usual real-time conditions. As a result, deviating system behavior must be expected, particularly with regard to time.

Separate configurations or behaviors must be taken into account for the use of further TwinCAT functions; these are described at Integration TwinCAT Functions.

The necessary parameterization is carried out via command line parameters on the one hand and a configuration file on the other.
