With
AB01 Measurement variable , the coordinate is uniquely identified in the green
frame. The "Variable" column is only visible in Developer mode (see
Chapter 2.3 Ac-
cess protection for data and settings
), for which the highest access level is required.
The variable identification drka establishes a unique identification for the physical var-
iable; this physical identification is assigned to the coordinate AB01 Measurement
variable .
If applicable, a coordinate can also be a function, then these designations can also
appear simultaneously.
The coordinates are arranged in a table, a coordinate system in the form of a matrix,
in which each column (also identified with menu) is identified with two letters and
each line is identified with a number. Furthermore, columns that belong together are
summarized in groups and each group has the same first letters, e.g. "A" for the
measurement columns. Each table as a (umbrella) term, or a heading, under which
all various points which have a logical connection with the term are summarized line
by line; for example, points such as "Unit", "Warning limit values", etc. are summa-
rized under the term "Absolute pressure". Chapters belonging together are summa-
rized under the first letters: AA, AB, AC, AD... / BA, BB, BC, ... / CA, CB, CC, CD.....
