To perform the calculation, in the Logical Level module you must firstly create a template library of our project and a parameter template of the DAQ-Subsystem in it. To create a template library go to the page of the DAQ-Subsystem and, through the context menu, create a template library start (Start). The configuration page of the obtained object of the template library (Fig.4.2.1) contains the "State" section of the status and operative control, and the "Configuration" section that contains only the default configuration fields and which will remain unchanged. In general we have:
- The section "State":
- mark the library accessible — set a sign opposite the corresponding field;
- specify the storage — leave the "Generic Storage" of the project;
- can control date of the last modification.
- Save the object.
