8 Sensor Analog Input Function Blocks
All gauge functions of the PxG55x are described in the Analog Input Function
Block. Depending on the device configuration there are up to 3 measuring systems
included.
Because the gauge includes three measuring systems, there are three Analog
Input Function Block Instances:
• Instance 1 represents the Capacitance Diaphragm Gauge (CDG) measuring
part of the gauge ( →  34).
• Instance 2 represents the Pirani measuring part of the gauge (→  37).
• Instance 3 represents the Atmosphere Pressure Sensor (ATM) measuring part
of the gauge ( →  40).
Because the gauge includes only one measuring system, there is only one Analog
Input Function Block Instance:
• Instance 1 represents the Pirani measuring part of the gauge (→  37).
This function block describes the functionality of the Capacitance Diaphragm
Gauge (CDG) measuring part of the gauge.
The PSG55x does not have a Capacitance Diaphragm Gauge (CDG)
and this function block (CDG) is not supported.
