Intended use
The bus node documented in this description CPX-FB06 is
exclusively for use as a participant in the Interbus.
The CPX terminal must only be used as follows:
– as intended in an industrial environment
– in original condition, without unauthorised modifications.
Only the conversions or modifications described in the
documentation supplied with the product are permitted.
– in excellent technical condition.
If standard ancillary components, such as sensors and actuat-
ors, are connected, the specified limits for pressures, temper-
atures, electrical data, torques, etc. must be complied with.
Observe the standards specified in the respective chapters
and comply with the regulations of the trade association and
the German Technical Control Board (TÜV), the VDE specifica-
tions or relevant national regulations.
Warning
• Only use PELV circuits in accordance with IEC/EN
60204-1 (protective extra-low voltage, PELV) for the elec-
trical power supply.
• Observe also the general requirements for PELV power
circuits in accordance with IEC/EN 60204-1.
• Only use voltage sources which guarantee reliable elec-
trical isolation of the operating voltage in accordance
with IEC/EN 60204-1.
Through the use of PELV circuits, protection against electric
shock (protection against direct and indirect contact) is en-
sured in accordance with IEC/EN 60204-1.

Bus nodes Create the connection to certain networks or fieldbusses, pass on control
signals to the connected modules and monitor their functioning
CP Compact Performance installation system, comprising a CP master with
one or more CP strings. The system consists of CP or CPI modules (without
or with extended functions).
CPA Pneumatic modules/valve terminal type 12
CPX bus Data bus via which the CPX modules communicate with each other and
are supplied with the necessary operating voltage.
CPX modules Collective term for the various modules which can be integrated into a
CPX terminal.
CMD software Parametrisation, commissioning and diagnostic software for stations on
the Interbus (configuration, monitoring, diagnostics).
CPX terminal Modular electric terminal type 50
DIL switch Dual-in-line switches consist of several switch elements with which set-
tings can be made.
FEC Front End Controller, e.g. CPX-FEC, can be used as:
– stand-alone system controller (PLC, stand alone operating mode)
– system controller (PLC, remote controller operating mode)
– fieldbus slave (remote I/O operating mode)
Handheld Handheld terminal (handheld, CPX-MMI) for CPX modules for commission-
ing and service purposes (man-machine interface, MMI)
IDigital input
ID code By means of the Identification code (in brief: ident. code), the interface
module ascertains the type and the process data length of all stations.
Interface module The interface module is the central device for controlling the Interbus data
ring. It exchanges the data transported serially in the data ring with the
higher-order controller or computer system and the lower-order Interbus
stations in both directions acyclically or cyclically.

Term/abbreviation Significance
I/Os Digital inputs and outputs
I/O diagnostic interface The I/O diagnostic interface is a bus-independent diagnostic interface at
I/O level, permitting access to internal data of the CPX terminal.
I/O modules Common term for the CPX modules which provide digital inputs and out-
puts (CPX input modules and CPX output modules).
Midi/maxi Pneumatic modules/valve terminal type 03
MPA Pneumatic modules/valve terminal type 32
ODigital output
Parameter data Data for parametrisation, diagnostics and configuration which are trans-
mitted acyclically in a multiplex procedure via the PCP channel.
PCP channel Stations that can also process parameter data are also known as PCP
stations. Communication between these stations and the interface mod-
ule takes place via the Peripheral Communication Protocol (in brief: PCP
or PCP channel). PCP is an integral part of the Interbus protocol.
Peripheral faults (PF) Malfunctions in the peripherals of Interbus stations are shown by means
of peripheral faults (dependent on station), e.g.:
– load voltage failure
– short circuit at the outputs, etc.
The peripheral fault is a common error message and does not contain any
module-specific information.
PLC/IPC Programmable logic controller/industrial PC
Pneumatics interface The pneumatics interface is the interface between the modular electrical
peripherals and the pneumatics.
Process data I/O data from the Interbus stations transmitted cyclically via the Interbus,
e.g. for:
– light barriers, sensors
– valves, contactors
– diagnostic I/Os.
Remote bus The remote bus bridges long distances within an Interbus system (main
string). With baud rates of 500 kBd and 2 MBd, it can be up to 12.8 km
long (from the interface module to the last connected remote bus sta-
tion). Individual segments can be up to 400 m long.

Warning
Before carrying out installation and maintenance work,
switch off the following:
• compressed air supply
• operating voltage supply for the electronics/sensors
• load voltage supply for the outputs and valves.
In this way, you can avoid:
– uncontrolled movements of loose tubing lines,
– accidental movements of the connected actuators,
– undefined switching states of the electronics.
Caution
The CPX bus node includes electrostatically sensitive com-
ponents for Interbus.
• Do not touch any contacts.
• Observe the handling specifications for electrostatically
sensitive devices.
They will help you avoid damage to the electronics.
