Integration (BPrcVal - subsystem-specific extension)
The Binary Process Value (BPrcVal) object supports following properties of the subsystem-specific extension Integration.
✳ Indicates a Siemens proprietary property.
Data type ✳ |
|
| |||
|---|---|---|---|---|---|
Data type defines the data type for encoding the subsystem-specific data type. | |||||
8 bit and 16 bit integer data formats with Registers: | |||||
Encoding format | Description | Byte order | |||
U8 | unsigned 8-bit | 00 aa | |||
U16-B | unsigned 16-bit; big-endian | bb aa | |||
In case of U8, S8: the most significant byte is 0. | |||||
32 / 64 bit integer data formats with Registers: | |||||
Encoding format | Description | Byte order | |||
U32-B | unsigned 32-bit; big-endian | dd cc bb aa | |||
S32-B | signed 32-bit; big-endian | dd cc bb aa | |||
U48-B | unsigned 48, big-endian | ff ee dd cc bb aa | |||
S48-B | signed 48, big-endian | ff ee dd cc bb aa | |||
U64-B | unsigned 64, big-endian | hh gg ff ee dd cc bb aa | |||
S64-B | signed 64, big-endian | hh gg ff ee dd cc bb aa | |||
Example: | |||||
16 / 32 / 64 bit float data formats with Registers: | |||||
Encoding format | Description | Byte order | |||
F16-B | float 16, big-endian | bb aa | |||
F32-B | float 32, big-endian | dd cc bb aa | |||
F64-B | float 64, big-endian | hh gg ff ee dd cc bb aa | |||
Example:
| |||||
Bit-Offset ✳ |
|
| |
|---|---|---|---|
"Bit-Offset" defines an offset in reading bitset of data (Coils, Discrete Inputs). This allows to support mass manipulation/correction of data point addresses. | |||
-1 |
| ||
0 |
| ||
100 |
| ||
Heartbeat timers ✳ |
|
| |
|---|---|---|---|
"Heartbeat timers" defines the heartbeat timer to be used to update the subsystem-specific data point if there is no change of "Present value" for a longer time. The interval values for H1, H2 can be configured in the Fieldbus-Management-Object. | |||
None | No updates of the subsystem-specific data point. | ||
H1 | Highest priority. Typical interval value: 5s…60s. | ||
H2 | Low priority. Typical interval value: minutes ... hours. | ||
Min repetition time ✳ |
|
|
|---|---|---|
"Min repetition time" defines the minimum wait time between two consecutive updates of the Modbus data point. "Min repetition time" is used to limit the network traffic in case of excessive changes of "Present value". "Min repetition time" may be zero to allow fast updates of MODBUS data points. | ||
