Pneumatic interfaces and pneumatic modules
Tab.2/5 and Tab.2/6 give an overview of the assigned ad
dress spaces of different pneumatic interfaces and modules.
Configuration of the
pneumatics (valves) The valves are configured according to the pneumatic
interface used:
Valves of type 03 (Midi/Maxi), type 12 (CPA) and
type44/45 (VTSA/VTSA−F or ISO):
When extensions are added to the valve side, only one
configuration is required for the pneumatic interface. In
the pneumatic interface, the number of valve coils is set
using a DIL switch.
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 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.
pneumatic modules of type MPA−P occupy 1 byte of
address space or 16 inputs.
pneumatic modules of type VPPM occupy 2 bytes of
address space or 1 byte I/O or 16 inputs and 16 outputs.
Pneumatic modules of type MPA−P and VPPM are analogue
modules. Note the order of the modules in addressing or I/O
mapping (see Tab.2/8).
Further information about the pneumatics can be found in the
corresponding pneum. descriptions (see document overview,
manuals for the CPX terminal in the CPX system manual
CPX−P.BE−CPX−SYS−...).
