According to the type of historical value, references are defined as follows:
-
for simple historical value
- name of the object of Historical value type
-
for one-column historical
value - name of the object of Historical value type along with a row index. In ESL, a row index must be enclosed
between square brackets (e.g. H.ColArchiv[2] (H.ColArchiv\HBJ,2,0))
-
for structured historical
value - name of the object of Historical value type along with a row index and a column name. List of columns is
given by an object of Structure definition type, that defines the structure of the historical value. In ESL, such a reference is
similar to the reference to an item of Structured variable type object (e.g. H.Struct[2]^ColName (H.Struct\HBJ,2,3)).
