Terminal CPX-P
Key features
Variants for controlling the CPX-P terminal (with bus node, without preprocessing)
Bus node
Different bus nodes are used to
integrate the terminal in the control
systems of various manufacturers.
The CPX-P terminal can therefore be
operated on commonly used fieldbus
systems:
PROFIBUS DP
PROFINET
DeviceNet
Integration in universal networks
based on Ethernet opens up new
possibilities. Faster data transmis
sion, real-time capability and above
all additional IT services such as file
transfer, web server, web monitor as
integrated website in the CPX-P
terminal, text message/e-mail alerts,
etc. open up a wide range of
synergies.
These include standardised and
universal communication technology
across all areas, including operating
level, management level and field
level in the production environment,
with protection to IP65.
The following protocols are supported:
EtherNet/IP
Modbus/TCP
PROFINET
Bus node Industrial Ethernet bus node
PLC
Fieldbus
Web
IT services:
E-mail
File transfer
PLC
Industrial Ethernet
Communication with higher-order
controller via fieldbus
No preprocessing
Fieldbus protocol dependent on
CPX bus node used
Up to 90 I/Os, depending on the
bus node used
Connection to a higher-order
controller directly via EtherNet/IP,
Modbus/TCP or PROFINET
No preprocessing
Monitoring via Ethernet and web
applications
Up to 300 I/Os
-H- Note
Every electrical connection can be
combined with an appropriate
number of I/O modules and/or
pneumatic components, depending
on its address capacity.
Likewise, every pneumatic variant of
the CPX-P terminal can be operated
with every electrical connection
variant.

Terminal CPX-P
Key features
Connection of inputs and outputs to the CPX-P terminal
Digital and analogue CPX I/O modules Electrical connection
The connection technology for
sensors and additional actuators
offers a wide range of digital and
analogue input and output modules
and is freely selectable – as
appropriate to your standard or
application.
The input/output modules can be
combined as required with the
connection blocks:
M12, 5-pin
M12, 5-pin, with quick lock and
metal thread
M8, 3-pin
M8, 4-pin
Sub-D, 25-pin
Harax®, 4-pin
CageClamp®
(with cover also to IP65/67)
Screw terminal and spring-loaded
terminal
CPX modules for NAMUR sensors Electrical connection
The electronics modules for NAMUR
sensors can only be combined with
certain connection blocks.
The input modules can be combined
as required with the connection
blocks:
M12, 4-pin
Screw terminal and spring-loaded

5CPX input module for NAMUR
sensors, intrinsically safe
design
6Actuator/machine component
with NAMUR sensors
CPX-P modules are suitable for con
figuring intrinsically safe or non-in
trinsically safe circuits depending
on the design selected.
This enables components from both
safe and hazardous zones to be
connected to the CPX-P terminal.
The components for the intrinsically
safe zone are marked in blue or
entirely coloured blue to distinguish
them visually.
-H- Note
Intrinsically safe circuits are circuits
which release so little energy during
operation, or in the event of certain
faults under specified test condi
tions, that no ignition can occur in a
particular potentially explosive
atmosphere.

Terminal CPX-P
Key features
Pneumatic variants of the CPX-P terminal
With valve terminal MPA-S – centralised
The electrical CPX-P terminal is a
modular peripheral system for valve
terminals.
The system is specifically designed
so that the valve terminal can be
adapted to suit different
applications.
The modular system design lets you
configure the number of valves,
inputs and additional outputs to
suit the application.
Ordering
The CPX-P terminal with valve
terminal is fully assembled according
to your order specifications and
individually tested. The finished valve
terminal consists of the electrical
peripherals including the desired
actuation and the selected
components from the MPA-S modular
system.
The CPX-P terminal with valve ter
minal is ordered using two separate
order codes. One order code defines
the electrical peripherals type CPX-P,
while the other specifies the
pneumatic components of the valve
terminal.
The electrical peripherals type CPX-P
can also be configured without a
valve terminal and can be used on a
fieldbus. For this order, only the order
code for the electrical peripherals is
required.
The order lists for the pneumatic
components can be found on
èInternet: mpa-s
(valve terminal MPA-S)
