1)
The function numbers are derived from the module number 3 (see Fig.2/2) and the calculation
4828+3*64+x = 5020 + x (x: see tables in section 2.1.4).
2)
Hexadecimal, can be useful with numerical values as an intermediate step for calculating the binary
values

Tab.3/12: Parameter for the proportional pressure regulator (example VPPM−6TA−
L−...OL6...)
In this parameterisation example the proportional pressure
regulator with the settings from Tab.3/12 behaves as follows:
Parameterisation faults and the set pressure limit values
(see below) are monitored, V
Out
/V
Val
are not monitored
The control behaviour is precise": The nominal pressure
is precisely actuated without overswinging
