Variable tables

To simplify parameter handling, the four most important physical sizes for profile

parameters are stored in separate "variable tables".

[5-4]

Principle: References to variable tables (here: References to VTSPEED)

 In case of several references to the same table position, a change of the value in this

table position affects several profiles at the same time. Thus, recurring profile

parameters only need to be changed on one position.

Note!

A value is assigned to a profile parameter by referring to a table position of the

assigned variable table.
• Hence, not the value itself is entered into the profile parameter but the index

of the table position which contains the value to be used.

• See the example in the illustration
