Pneumatic interfaces and pneumatic modules
The Tab.2/6 to Tab.2/9 give an overview of the assigned
address spaces of different pneumatic interfaces and
modules.
The valves are configured according to the pneumatic
interface used:
 Valves of type 44 (VTSA, ISO), type 03 (Midi/Maxi) or
type12 (CPA):
When extensions are added to the valve side, only one
identifier is used for
the pneumatic interface. In the pneu
matic interface the number of valve coils is set with a DIL
switch (grid pattern 1 byte).
 Valves of type 32 and 33 (MPA, MPA−F and MPA−P or
VPPM pneumatic modules):
From the technical point of view, the individual MPA
pneumatic modules each represent an electric module for
controlling the attached valves.
A configuration is required for each pneumatic module of
type MPA:
 Pneumatic modules of type MPA1 each occupy 1 byte
of address space or 8 outputs (an identifier),
regardless of how many valves are attached to the
pneumatic module.
 Pneumatic modules of type MPA2 each occupy 1
byte
of address space or 8 outputs, but only 4 bits are used.
The identifiers can be grouped together with modules
of the same type (see Fig.2/1).
 Pneumatic modules of type MPA−P each occupy 1 byte
of address space or 16 inputs.
 Pneumatic modules of type VPPM each occupy 1 byte
of address space (inputs/outputs) or 16 inputs and
16 outputs.
