*) According to parameter data type **) According to data type value (ID 21)
The Block Type ID Parameter contains an ID which describes the block type. The
block type ID of the "Sensor Analog Input Function Block" is set to "2". The other
defined block types are listed in Appendix B.
This parameter enables the setting of the Alarm Status Bits (ID 20):
• 0 = disable (Default)
• 1 = enable
This parameter enables the setting of the Warning Status Bits (ID 20):
• 0 = disable (Default)
• 1 = enable
The process value contains the measurement value of the Diaphragm Gauge
transducer instance (CDG), transformed on the basis of the chosen data unit. If the
device is not in state EXECUTING (ID 25, Device Block), the Process value is set
to the value specified by the Safe State (ID 39). This could be the Safe Value, Last
Value, Full Scale, Zero, device specific, or vendor specific.
This parameter provides the Alarm and Warning State of this block instance
according to the following table:
Bit Definition
0 High Alarm Exception
1 Low Alarm Exception
2 High Warning Exception
3 Low Warning Exception
4 Reserved
5 Reserved
6 Reserved
7 Reserved
This parameter determines the data type of ProcessValue and all related
parameters. Two data types are supported: Float and Integer16.
This parameter can be changed via master class 2 acyclic data transfer only if the
device is not in cyclic data transfer with master class 1. The data type is valid for all
block instances of the device. This means that all parameters determining the data
type will have the same value. A change of one data type parameter changes all
others to the same value.
It is possible to adjust the data type during cyclic data transfer start up (setting of
configuration data, CFG-String. In this case the data type value is updated with the
value requested by the configuration data.
The data type can be changed from Float to Integer16. After startup it is set to the
value stored in the EEPROM. The default setting is "Float".
