AI Block Parameter Attribute Definitions
The following table describes the parameters that are available in the analog input function block. Each line item in the table defines the element and specifies the requirements for each element.
Absolute | Parameter | Description |
Index | ||
| Profibus PA Specific Block |
|
| Header |
|
16 | BLOCK_OBJECT | This object contains the characteristics of the |
|
| blocks. |
17 | ST_REV | The modification of at least one static parameter in |
|
| a block has to be incremented by the according |
|
| ST_REV at least by one. |
18 | TAG_DESC | Every block can be assigned a textual TAG |
|
| description. The TAG_DESC must be unambiguous |
|
| and unique in the fieldbus system. |
19 | STRATEGY | Grouping of Function Block. The STRATEGY field |
|
| can be used to group blocks. |
20 | ALERT_KEY | This parameter contains the identification number |
|
| of the plant unit. It helps to |
|
| identify the location (plant unit) of an event. |
21 | TARGET_MODE | The TARGET_MODE parameter contains desired |
|
| mode normally set by a control application or an |
|
| operator. The modes are valid alternatively only, |
|
| i.e. only one mode can be set at one time. A write |
|
| access to this parameter with more then one mode |
|
| is out of the range of the parameter and have to be |
|
| refused. |
22 | MODE_BLK | This parameter contains the current mode, the |
|
| permitted and normal mode of the block. |
23 | ALARM_SUM | This parameter contains the current states of the |
|
| block alarms. |
24 | BATCH | This parameter is intended to be used in Batch |
|
| applications. Not implemented in 8732E device. |
25 | RESERVED by PNO |
|
26 | OUT | The Function Block parameter OUT contains the |
|
| current measurement value in a vendor specific or |
|
| configuration adjusted engineering unit and the |
|
| belonging state in AUTO MODE. The Function |
|
| Block parameter OUT contains the value and status |
|
| set by an operator in MAN MODE. |
27 | PV_SCALE | Conversion of the Process Variable into percent |
|
| using the high and low scale values. The |
|
| engineering unit of PV_SCALE high and low scale |
|
| values are directly. |
28 | OUT_SCALE | Related to the PV_UNIT of the configured |
|
| Transducer Block (configured via Channel |
|
| parameter). The PV_SCALE high and low scale |
|
| values follow the mapped to last 16 characters of |
|
| DEVICE_ID_STRING parameter in Mfg. Block. |
29 | LIN_TYPE | Type of linearization. The 8732E only supports “No |
|
| linearization”. |
30 | CHANNEL | Reference to the active Transducer Block which |
|
| provides the measurement value |
|
| to the Function Block. |
31 | RESERVED |
|
32 | PV_FTIME | Filter time of the Process Variable. |
