Local Control

The slow system control consists of:

- Pfeiffer pressure gauges
- one dsPic board running an embedded firmware
- one high level PC application

The dsPic acquires the pressure value from the Pfeiffer gauge, with the Pfeiffer protocol working on RS485, and sends the pressure to a high level PC application.
