Ignition Get Value From Tag. the value of a tag can come from different sources. A tag source will define its type. Tags are points of data and may have static values or dynamic. you can use square brackets to read values from a dataset in expressions. Tags can be opc type, memory type,. The following will read the “id” column of. expression language and syntax. to use a dataset tag field value you will have to read and convert to a pydataset. The expression language is used to define dynamic values for component properties and expression tags. you make a readblocking () call. expression tags use ignition's expression language to derive a value. They are useful when referencing another tag's value, or. X = system.tag.readblocking ( [' [someprovidername]path/to/tag']). reading a tag from a script is accomplished with the system.tag.readblocking() function, which.
