Instance 2 of the Analog Sensor Input Function Block describes the functionality of
the BA/HP measuring part of the gauge.
In Instance 2, the same attributes as in Instance 1 are supported:
ID Name Structure Data type Bytes Access Store
19 Process Value
(PV) Simple According to
Parameter Data
Type - 0_XI
1_R
2_R D
20 Status Simple Unsigned8 1 0_XI
1/2_R D
21 Data Type Simple Unsigned8 1 2_R/W N
22 Data Units Simple Unsigned16 2 2_R/W N
23 Reading Valid Simple Boolean 1 1_R
2_R D
24 Full Scale Simple According to
Data Type value
(parameter 21) - 1/2_R N
39 Safe State Simple Unsigned8 1 1/2_R/W N
40 Safe Value Simple According to
Data Type value
(parameter 21) - 1/2_R/W N
44 Overrange Simple According to
Data Type value
(parameter 21) - 1/2_R N
45
Underrange Simple According to
Data Type value
(parameter 21) - 1/2_R N
The Process Value contains the measured value of the BA/HP Device Instance in
the currently selected data unit (ID 22) and in the selected data type (ID 21).
If the device is not in the EXECUTING status (ID 25, Device Block), the value
defined in the Safe State is output.
Values output in the data unit COUNTS can be converted into a pressure value by
means of the following formulas:
