Valve terminals MPA-L
Key features – Electrical components
Fieldbus connection/CPX terminal
All functions and features of the
electrical peripherals CPX are
permitted in connection with the CPX
interface.
This means:
 The valves and outputs are supplied
via the system supply for the CPX
terminal
 The valves can optionally be
actuated or switched off separately
from the outputs
The pneumatic interface (left-hand
end plate) serves as an adapter
between the two current feeds.
In the pneumatic interface, the serial
signals from the CPX terminal are
converted into parallel signals.
The number of addresses (solenoid
coils that can be connected) is set via
a selector (rotary switch) on the
pneumatic interface to between
4 … 32 solenoid coils. The default
setting on delivery provides for
32 addresses. This enables extension
s
to be pre-assigned in a control
program and called up by means of
manual settings.
After converting or extending the valve
terminal, the number of output
addresses occupied by the pneumatic
components must be checked and if
applicable adjusted.

I-Port interface/IO-Link
The I-Port interface/IO-Link enables
the valve terminal CPV to be
connected to the following systems:
 I-Port master from Festo
(CPX terminal, CECC)
 Fieldbus node CTEU from Festo
 IO-Link master
The maximum distance between the
I-Port/IO-Link master and valve
terminal with I-Port interface/IO-Link
is 20 m.
The 5-pin connecting cables contain
the power supply for the valves,
separate from this is the power supply
for the internal valve terminal
electronics and the control signals.
