Valve terminals MPA-L
Key features
Fieldbus connection via the CPX system
An integrated fieldbus node manages
communication with a higher-order
PLC. This enables a space-saving
pneumatic and electronic solution.
Valve terminals with fieldbus
interfaces can be configured with up
to 32 sub-bases.
The CPX terminal also enables the
integration of digital and analogue
electrical inputs and outputs,
pressure sensors and controllers for
pneumatic or electric positioning
axes.
A detailed description of the extensive
functionality can be found in the
documentation for the CPX terminal

Fieldbus protocols/CPX variants:
 PROFIBUS DP
 PROFINET
 INTERBUS
 DeviceNet
 CANopen
 CC-Link
 EtherNet/IP
 Front End Controller
Remote I/O
 Modbus/TCP
 EtherCAT
Control block connection via the CPX system
Controllers integrated in the Festo
valve terminals enable the
construction of stand-alone control
units to IP65, without control
cabinets.
In the slave operating mode, these
valve terminals can be used for
intelligent preprocessing and are
therefore ideal modules for designing
decentralised intelligence.
In the master operating mode,
terminal groups can be designed with
many options and functions that can
autonomously control a medium-sized
machine/system.
Fieldbus connection via the CTEU system
Communication with a higher-level
PLC is managed by a fieldbus node
mounted directly on the I-Port
interface.
Valve terminals with an I-Port
interface can be configured with up to
32 sub-bases.
A detailed description of the extensive
functionality can be found in the
documentation for the fieldbus
modules CTEU/installation

I-Port interface/IO-Link
I-Port/IO-Link consists of a central
master and the devices with I-Port
interface/IO-Link connected via
special connecting cables. This
permits a decentralised layout of the
devices.
The connection type corresponds to a
star topology.
In other words, only one module or
valve terminal can be connected to
each I-Port.
The I-Port interface from Festo is
based on IO-Link and is compatible
with IO-Link in certain areas.
As well as communication, the I-Port
interfaces also handle the power
supply for the connected devices.
The maximum length of a string is
20 m.
