1. System overview CPI/CP system
The CPI/CP system consists of individual modules which are
connected to each other by means of CP cables. In this way it
is possible to decentralize the arrangement of the CP system.
The compact CP valve terminals can be mounted very close to
the cylinders to be controlled. This enables short compressed
air
tubing to be used.
System losses can be minimized if short compressed air
tubing is used and the times required for pressurising and
exhausting the tubing can be reduced.
This enables smaller valves with sufficient flow to be used,
thereby helping to reduce costs.

1.1.2 Rules for extending the CPI system
The CPI system supports a different number of modules per
CP string, depending on the type of CP master and on the
CPI/CP modules connected.
The CPV Direct is a CPI master.
Modules can be placed in two different groups:
CPI modules (with extended functions)
CP modules (without extended functions)
Rules and properties
CPI system Max. 4 modules on the CP string
CPI master A mixture of CPI/CP modules is possible on CPI masters:
CPI modules Modules always have an incoming and continuing interface on all CPI modules
1)
with extended functions
2)
without extended functions
Max. 32 inputs and 32 outputs (per CP string)
The sequence of the modules within the CP string is optional
Only one CP input module is possible at the end of a string
Only one CP valve terminal2) or one CP output module2) is possible per CP
string
Unused" locations on the CP string can be filled" with CPI modules
(input modules, output modules) and valve terminals with CPI connection
1)
Tab.1/2: Rules for extending the CPI system
Note
Irrespective of the type of CPI/CP modules, not more than
32 inputs and 32 outputs may be connected (sum of all
modules on a CP string).
This means that a CP string can be extended by maximum
2 CP valve terminals with CPI ability, as CP valve terminals
always occupy 16 output addresses.

1. System overview CPI/CP system
1.1.4 Basic rules for addressing
Addressing depends on:
CPI/CP master used
The fieldbus protocol used
The following rules apply:
Addressing is carried out in ascending order of connec
tion beginning on the CP master.
In the case of CP masters without extended functions,
each CPI/CP module occupies 16 inputs or 16 outputs,
irrespective of the design.
In the case of
CPI masters with extended functions, the
following difference applies:
Modules without extended functions usually occupy
16 inputs or 16 outputs.
Depending on the type, modules with extended func
tions occupy 8 ... 32 inputs or 8 ... 32 outputs.
Note
Further information on addressing can be found in the
relevant manuals for the CP masters.

Reaction to shor t circuit in the sensor supply
If there is a short circuit, the input module will switch off the
power supply to the sensors and communicate the fault to
the CPI/CP master. The status LEDs will be switched off and
the inputs of the module supply a 0−signal. After the short
circuit or overload has been eliminated, the module must be
separated from the supply voltage in order to reset the short
circuit/overload.
