Data source linked to a real-time source.
Properties of the xoScadaSource object
Property |
Data Type |
Description |
|---|---|---|
Bit |
Number |
Bit used in the operation indicated by the BitOperation property, which ranges between 0 (zero) and 31. The default value of this property is 0 (zero) |
Number |
Operation to apply to the bit indicated in the Bit property. Possible values for this property are 0: No operation, 1: Extraction of an individual bit, or 2: Bit-mask operation |
|
Mask1 |
Number |
Comparison mask for use when the BitOperation property is equal to 2 (two) |
MaskX |
Number |
Logical AND mask for use when the BitOperation property is equal to 2 (two) |
Boolean |
Enables or not the processing of multiple statuses |
|
Quality |
Number |
Quality, in OPC standard |
StateColor |
Color |
Color representing the current status |
Tag |
Link |
Link to an IOTag-type object |
TextValue |
Text |
Text corresponding to a condition of multiple statuses |
TimeStamp |
Date and time |
Last timestamp |
Value |
Variant |
Current value, in engineering units |
When starting the execution of this object or when executing the CustomConfig event in Studio, a Link between the object indicated in the Tag property and the Value, Quality, and TimeStamp properties is created. This Link depends on the value of the BitOperation property:
•0 (zero): The Tag's Value property receives the value of the Value property
•1 (one): GetBit(Tag.Value, Bit) receives the value of the Value property
•2 (two): (Tag.Value AND MaskX) is equal to Mask1 and receives the value of the Value property
If the Multistate property of the parent object, which is an xfDiscreteInfo type, is equal to True, then the first child object with an xoScadaSource type whose MultiState property is equal to True is the current condition.
