Attribute name | Attribute value type | Meaning | |||||||
---|---|---|---|---|---|---|---|---|---|
TIM | Absolute time | Time of the last object value change. | |||||||
LIM | Integer | Value limit state [0-InLimit, 1-VL_Limit, 2-L_Limit, 3-H_Limit, 4-VH_Limit, 5-LimitsProblem]. Depending on the object value in relation to the defined limits, the attribute gains these values:
| |||||||
| Boolean | Value validity (TRUE - valid value, FALSE - invalid value). | |||||||
ALF | Boolean | Indication of an active process alarm of the given object (the object has an active process alarm - TRUE, if not - FALSE). | |||||||
ALQ | Boolean | Acknowledgment indication of the active process alarm of the given object (the active alarm is not acknowledged, i.e. it hasn't been acknowledged by an operator - TRUE or it is acknowledged, i.e. it was acknowledged by an operator - FALSE). | |||||||
ALT | Absolute time | Time of process alarm value assignment. | |||||||
| Integer | Process alarm type. Depending on the evaluation of process alarms defined for the given object, the attribute gains the following values:
| |||||||
WEA | Boolean | Indication of a weak (suspicious) object value. A weak value is a value, that is not valid in the system, because all conditions of its validity are not still met. The object value is a weak one - TRUE, or the object value is not a weak one - FALSE. | |||||||
NAK | Boolean | Acknowledgment indication of the last object value change. Object value change is not acknowledged - TRUE if it is - FALSE. | |||||||
TRA | Boolean | Transient state indication of the object value. A transient state occurs, when the command to set a value was executed, but the backward reading did not verify the setting of value. The object value is in Transient state - TRUE, if not - FALSE. | |||||||
DEF | Boolean | Default state indication of the object value. Default state occurs, when an I/O tag value gained by the communication process D2000 KOM is replaced by another value - a control object value, or it is set manually by an operator in process D2000 HI. The object value is in Default state - TRUE, if not - FALSE. | |||||||
MAN | Boolean | Manual state indication of the object value. The manual state is active if the object value can be controlled (i.e. providing that a user has sufficient access rights or ESL script). A manual attribute may be set only for values of objects Remote tag, I/O tag, User variable, Structure variable item. | |||||||
FLX | Integer | All attributes. Integer number, individual flags in the order FLA FLB FLC ... FLP are assigned to its binary representation. For example, the value of 1 is corresponding the situation, when the value of the flag A is TRUE and the values of all other flags are FALSE. | |||||||
FLA .. FLP | Boolean | A particular flag value of an object value [FLFlagName]. | |||||||
DIM | Integer | It returns the structure size. It is usable only for values of Structure type. | |||||||
HBJ | Integer | It returns the unique identifier of an object in the D2000 system. Value is HBJ type, free convertible to Int type. | |||||||
CNX | Integer | It returns the index of a structural column. The attribute is applicable to the reference to a structure item: SV.Structure^Int\CNX returns the value 2. | |||||||
CNM | Text | It returns the name of a structural column. The attribute is applicable to the reference to a structure item: SV.Structure^Text\CNM returns the value "Text". | |||||||
CNR | Integer | It returns the count of structural columns. It is usable only for values of Structured variable type and Structure definition type. | |||||||
ALC | Boolean | Indication of an active critical alarm of the given object (the object has an active critical alarm - TRUE, if not - FALSE). | |||||||
ROW, COL | Integer | If the attribute is applied to an Object type of item that refers to a item of another structure, the attribute returns the row or column to which the item refers. For example:
SET AS |
