Warning!
Dangerous electrical voltage!
Before commencing the installation
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally restarted.
• Verify isolation from the supply.
• Earth and short circuit.
• Cover or enclose neighbouring units that are live.
• Follow the engineering instructions (AWA) of the
device concerned.
• Only suitably qualified personnel in accordance with
EN 50110-1/-2 (VDE 0105 Part 100) may work on
this device/system.
• Before installation and before touching the device ensure
that you are free of electrostatic charge.
• The functional earth (FE) must be connected to the protective
earth (PE) or to the potential equalisation. The system installer
is responsible for implementing this connection.
• Connecting cables and signal lines should be installed so
that inductive or capacitive interference do not impair the
automation functions.
• Install automation devices and related operating elements in
such a way that they are well protected against unintentional
operation.
• Suitable safety hardware and software measures should be
implemented for the I/O interface so that a line or wire
breakage on the signal side does not result in undefined
states in the automation devices.
• Ensure a reliable electrical isolation of the low voltage for the
24 volt supply. Only use power supply units complying with
IEC 60364-4-41 (VDE 0100 Part 410) or HD 384.4.41 S2.
• Deviations of the mains voltage from the rated value must
not exceed the tolerance limits given in the specifications,
otherwise this may cause malfunction and dangerous
operation.
• Emergency stop devices complying with IEC/EN 60204-1 must
be effective in all operating modes of the automation devices.
Unlatching the emergency-stop devices must not cause restart.
• Devices that are designed for mounting in housings or control
cabinets must only be operated and controlled after they have
been installed with the housing closed. Desktop or portable
units must only be operated and controlled in enclosed
housings.
• Measures should be taken to ensure the proper restart of
programs interrupted after a voltage dip or failure. This should
not cause dangerous operating states even for a short time.
If necessary, emergency-stop devices should be implemented.
• Wherever faults in the automation system may cause
damage to persons or property, external measures must be
implemented to ensure a safe operating state in the event of
a fault or malfunction (for example, by means of separate limit
switches, mechanical interlocks etc.).

About This Manual
Structure
The XC600 PLC is designed for the control of machines and
systems. This controller provides the basis for an extensive PLC
system using interfaces for the standard networks PROFIBUS-DP,
CANopen and ETHERNET, for connecting remote expansion
modules and intelligent devices.
The documentation for the PLC is divided into five sections:
• Hardware and engineering
• PC-XC600 connection
• Creating an example project
• Functions of the operator modules
• Menu overview of the operator module
The Chapter “Hardware and Engineering” provides information
on the installation and engineering of the PLC as well as on the
possible PLC settings.
In order to communicate with the PLC, the PC must be connected
to it via the Ethernet network. The configuration of the Ethernet
module and the XC600 is described in the Chapter “Creating the
connection between PC and XC600” from Page 20.
Use of the XSoft software is then explained using a simple
example. This will show you how to configure and program the
controller. After you have downloaded the project you can then
test it as described in a Chapter “Creating an Example Project”
on Page 23.

1 Hardware and Engineering
Setup
The XC600 PLC has a modular design. The basic unit consisting of
the base, power supply, CPU and operator modules can be
expanded with function modules for communication. Modules for
the standard PROFIBUS-DP and CANopen networks are therefore
provided for this purpose. They provide the controller with access
to the I/O devices that log process data signals and control
actuators.
The process signals can also be connected locally with XI/ON input
and output modules. This requires the use of the power supply
module with the integrated XI/ON interface and the base module
with the XI/ON adapter.
A module consists of a circuit board that is embedded in a frame.
The special frame design makes it possible to stack the modules
together, thus allowing compact functional units to be combined
to suit the requirements of the task at hand.
The circuit boards of the individual function modules meet the
requirements of the PC/104+ specification. In addition to dimensions, the specifications also stipulate the requirements of the
PC/104+ bus that connects the modules. This bus also carries the
power supplies from the power supply module to the individual
function modules.
A configuration containing XI/ON input/output modules must
always include theXC-ADP-XION base module with the
XC-POW50-XION-UPS power supply module. The power supply
module adapts the PC/104+ bus to the XI/ON module bus using
the XI/ON interface. This bus is connected out from the base
module. The adapter on the base module provides the interface to
the XI/ON modules. The 24 V DC field power supply of the XI/ON
modules is also connected to the base module.

Mounting
Caution!
Only remove or fit modules with the power supply
switched off. Discharge yourself on any electrostatic
charge before touching a module.
Voltage peaks on the bus connector may cause
malfunctions or damage to the module.
The modules are supplied separately and must be fitted together.
Observe the order shown in Figure 1 and fit the base module first
of all on a horizontal mounting rail.
Fitting/removing modules
The back of the base module is provided with an eccentric plate.
Using a cheese head screwdriver, turn this plate so that it grips
underneath the mounting rail and secures the base module. The
front of the plate has number markings to ensure that it is positioned correctly.

Engineering
Control cabinet design
The arrangement of components in the control cabinet is an important factor in ensuring that system and machine functions are free
of interference. During the planning and design stages, as well as
during implementation, it must be ensured that the power and
control sections are separated. The power section includes the
following components:
• Contactors
• Coupling modules
• Transformers
• Frequency inverters
• Current converters
Dividing the control cabinet into to areas with different power and
interference levels is recommended as an effective prevention
against electromagnetic interference. In small control cabinets,
this can often be provided sufficiently by using separators in order
to reduce interference.
8
12/01 AWB2700-1428GB
Engineering
Ventilation
A minimum gap of 5 cm between passive components must be
provided in order to ensure sufficient ventilation. If active components (e.g. load power supply, transformers) are fitted next to each
other, a minimum gap of 7.5 cm must be ensured. Observe the
values specified in the technical data.
Device arrangement
Mount the UPS unit and the controller horizontally in the control
cabinet as shown in the following figure.

X Observe the following minimum gaps:
– Between heavy current cables and signal cables at least
10 cm
– Between heavy current and data/analog cables at least
30 cm.
– Make sure that the supply and return cables belonging to
each circuit are laid together. The opposing direction of
current flow means that the sum of all the currents is zero, so
that any fields which are produced are compensated.
Suppression of interference sources
X Keep all suppressor circuits as close to the interference source
(contactor, relay, solenoid) as possible.
Switched inductive loads should always be suppressed.
h
Shielding
X Connections to data interfaces should be implemented with
shielded cables. General guideline: the lower the coupling
impedance, the better the shielding effect.

Preventing interference
Cabling and wiring
The following cable types are required:
• Heavy current cables (e.g. power cables carrying high currents,
or cables to current converters, contactors, solenoid valves)
• Control and signal cables (e.g. digital input cables)
• Measuring and signal cables (e.g. fieldbus cables)
Keep heavy current cables, control cables and signal
h
cables as far apart from each other as possible. This will
prevent capacitive and inductive interference. If separate
cable routing is not possible, the interference cable must
be shielded.
Ensure correct cable routing inside and outside of the control
cabinet in order to keep interference to a minimum:
X Avoid laying cables with different power levels in parallel.
X Always separate AC from DC cables.
Lightning protection measures
External lightning protection
All cables linking buildings must be shielded. Metal conduits are
recommended as the most suitable means of protection. Signal
cables must be provided with overvoltage protection in the form of
varistors or other overvoltage arresters. This should be implemented as close as possible to the point where the cable is routed
into the building, and at least before the cable enters the control
cabinet.
Internal lightning protection
Internal lightning protection includes all measures that reduce the
effect of lightning current and its electrical and magnetic fields on
the metallic installation and electrical system inside a building
complex. This consists of:
• Lightning protection potential equalisation
• Shielding
• Use of overvoltage protective devices.
Further information on cabling and shielding is provided in the
following manuals:
• AWB27-1287 ”EMC Design Guide for Automation Systems”.
• TB27-001-GB ”The Electromagnetic Compatibility of
Automation Systems”.
• TB27-022-GB ”The Electromagnetic Compatibility (EMC) of
Machines and Plants”.

supply module

b UPS device
If the supply voltage to the UPS device drops, the controller is
supplied with the battery supply voltage. The contact ”C1” in the
UPS device opens and the circuit at the Power Fail input of the
power supply module is interrupted. This will cause the controller
to initiate the PFI signal, which will cause the system to shut down.
The controller requires approximately two minutes to do this.
By connecting the Battery off input of the UPS to contact C2, the
UPS device can switch off the battery supply voltage after two
minutes. The battery is then used only for these two minutes so
that further battery backup protection is ensured occur. If power
is restored after two minutes, the controller will start up again
according to how the operating mode selector switch is set.
A different routine is followed if the power supply to the UPS
returns within two minutes: while the power to the UPS device has
failed, the controller is at first initially supplied by the battery
voltage until power is restored. As the UPS device signals the
power failure to the controller (Power Fail input), the controller
starts a system shutdown (2 minutes). The following message will
be shown on the display: ”PFI shut down in progress”.The operation ends with the message ”TURN OFF YOUR CONTROLLER” on
the display.
In this case, the controller has not detected a power failure. When
the PLC is restarted, the power supply of the UPS system must be
switched off and on again. If the start is to take place automatically, an on-delayed timer must be used to lengthen the interruption to more than 2.5 minutes (a Fig. 10).

In the event of a power failure the PLC will then shut down after
two minutes and will restart automatically after 2.5 minutes.

Task of the XC-ADP-XION module
The module controls the XI/ON data bus and provides the power
supply (5 V) to the XI/ON modules. The base module has a separate connection for the 24 V DC field power supply of the XI/ON
modules. It also has a C connection to which the potential for the
C rails of the XI/ON modules can be connected.
How to expand the controller with XI/ON modules is described in
the XI/ON manuals, ”Hardware and Engineering”, e.g.
AWB2700-1394.

Task
The modules convert the 24 V DC power supply to +5 V DC,
+12 V DC and –12 V DC (for XC-POW50-XION-UPS) supplies, and
provide the voltages for the function modules via the PC/104+
bus. The XC-POW50-XION-UPS power supply module also
provides a 5 V DC supply to XI/ON modules via the XI/ON module
bus.
As the XC600 controller is PC-based, it must be ensured that the
program is closed and the operating system shut down properly
before the device is switched off. The supply of the power supply
module must therefore be backed up by means of an uninterruptible power supply (UPS). If the supply voltage drops, the UPS sends
a Power Fail signal to the PLC which then initiates a shutdown of
the system. The UPS unit will then keep the output voltage
constant for at least two minutes in order to ensure the troublefree completion of the shutdown.
Setup
The module contains a board with the PC/104+ bus. Another
board provides the interface for the XI/ON modules and connects
the power supply module with the base module.

errors occurring during the starting of the PROFIBUS-DP
line.
Start/Stop behaviour
Setting the OMS to the STOP position will cause all the outputs of
the remote devices to be set to 0.
An interruption on the DP line will cause all inputs of the disconnected devices (receive data) to be interpreted by the PLC as 0
signals and the outputs set by the PLC in the output module to be
reset.

X Assign the memory range beginning with start address CE000
to the first module (CANopen or PROFIBUS-DP) to be
configured.
The input/output devices assigned to this module are connected to
the module bus system via address CE000.
X Assign the range starting with address CC000 to the second
module and D4000 to the third.

terminating resistor can be enabled or disabled via the
slide switch on the plug.
XC-NET-CAN CANopen module
General
The module provides the ISO 11898 interface between the CPU
module and the CANopen bus.
Task of the module
The module provides the master function for CANopen bus. It
organises and operates the data exchange between the user
program and the connected slaves. Up to 126 nodes can be
connected to a line.
The CANopen modules can be fitted between the power supply
module and the CPU module. Up to three modules (PROFIBUS-DP
or CANopen) can be fitted.
2 CAN_L CAN_L bus cable
3 CAN_GND CAN reference potential
7 CAN_H CAN_H bus cable
Power supply
The power supply module provides the 5 V supply to the modules
via the PC/104 bus.
Set the system power supply so that the connected remote stations
on the CANopen line are switched on simultaneously or before the
controller. This prevents any errors occurring during the starting of
the CANopen line.
Start/Stop behaviour
Setting the OMS to the STOP position will cause all the outputs of
the remote devices to be set to 0.
An interruption on the line will cause all inputs of the disconnected
devices (receive data) to be interpreted by the PLC as 0 signals and
the outputs set by the PLC in the output module to be reset.
Devices that are still connected with the PLC will continue to be
interrogated.
Configuring the module address
Up to three XC-NET-DP-M (PROFIBUS-DP) or XC-NET-CAN
(CANopen) modules can be used in any combination. Reserve a
memory range for each module in the CPU by defining a module
address for each one:

X Set the address for each module using the jumpers in the
jumper field from range 13 to 17 (a following figures).
