Definition of Time Steps
The following figure illustrates the differences in a small model between:
| • | Sample Time |
| • | Run Time |
| • | Measurement Time |
The 'Run Time' is dependent of:
| • | Computer power |
| • | Model complexity |
| • | Solver complexity and accuracy |
The 'Sample Time' has an impact on the accuracy of the simulation. A larger sample time will lead to a more inaccurate simulation result.
The 'Measurement Sample Time' affects the amount of data which must be stored.
Models in the Network
Each model at the target computer has one number. The number has three digits and start with '000'. The maximum number of models is 1000, with the highest model number being '999'.
With the IP-Address and the model number each model can be selected.
Note: Each RT-Target computer has its own IP-Address; otherwise it is not inside of a network. The so called “localhost” IP-Address is “127.0.0.1”.
Signals in the Network
Each model can have infinite numbers of input and output. The number is called Signal-ID. The Signal ID starts with 1.
Measurement
Data can be logged in the RAM or file on the target computer.
The trigger measurement can be started via the MDI server (e.g. by Vision) - using switch trigger start.
The following figure shows the start of a measurement by a internal event (level trigger). The measurement will start if the trigger signal passes the trigger-level in the correct direction.
