- 1. Using a Visual Studio with TwinCAT installed, open the project via Open Project ....
- 2. Configure signing for this project by switching on TwinCAT signing with a right-click on Project->Properties->Tc Sign and configure your certificate and password if necessary.
Further information on signing C++ projects can be found in the chapter TwinCAT. - 3. Select your target system.
- 4. Build the sample (e.g. Build->Build Solution).
- 5. Activate the configuration by clicking
.
- The sample is ready for operation.
Description
This sample exclusively deals with time measurement such as
- Querying the task cycle time in nanoseconds
- Querying the task priority
- Querying the time when the task cycle starts at intervals of 100 nanoseconds since January 1, 1601 (UTC)
- Querying the distributed clock time when the task cycle starts in nanoseconds since January 1, 2000
- Querying the time when the method is called at intervals of 100 nanoseconds since January 1, 1601 (UTC)
