2.6.5 COLBAS Access to Point Parameters
Each data point has a Technical Address (TA). Any point can also be given a User
Address (UA).
Fully defined point data may therefore be obtained by specifying
–
the respective point's address and
–
the abbreviated parameter name.
There is a similarity between COLBAS variables and point parameters. In fact, COLBAS
variables and parameters are handled in similar ways.
COLBAS Variables Point parameters

and a variable value.
