The installation-saving controller
The FEC Standard is not just a new
mini controller. It shows that there is
still room for innovation in mini
controllers at the start of the new
millennium.
With its robust extruded aluminium
housing, it demonstrates that
compact design and toughness can go
hand in hand.
Its connector system is accessible
from the front, ensuring no wastage of
space within control cabinets. And the
sensor/actuator connector system
SAC, making its world premiere in this
product, very largely replaces terminal
strips in the I/O area.
This means that control cabinets with
FEC Standard have a decisive
advantage: Up to 50% less space
required, and up to 40% less time.
Thanks to the integration of a high-
speed counter into every CPU, this
mini controller is well able to carry out
counting and simple positioning
operations. Additionally, the optional
analogue inputs/outputs turn a smart
mini controller into a smart process
controller.
The two serial interfaces in every CPU
make the FEC Standard into a talented
communicator which allows program-
ming via one interface and operation
and monitoring via the other, at the
same time. The leading concept in
communication today is Ethernet, the
“network of networks”. This can of
course be integrated into
FEC Standard as an option. After all,
smart automation technology
demands smart network technology.
With Ethernet and a web server, the
FEC Standard paves the way for the
visualisation technology of tomorrow:
Controller surfing.

3.Controllers FEC, Standard
Key features
Hardware
The FEC Standard has a clip for a top-
hat rail and corner holes for bolt-
mounting using a mounting plate. All
connections are accessible from the
front; there is no need for additional
space for connections from above or
below.
Serial interfaces
Every FEC Standard is equipped with
two serial interfaces – COM and EXT.
These are universal TTL interfaces
with a maximum data transmission
rate of 115 kbits/s. Depending on
requirements, the interfaces can be
used as RS232c (SM14 or SM15) or
RS485 (SM35) interfaces. Adapters
should be ordered separately. The
COM interface is generally used
together with the SM14 for program-
ming, while the EXT interface can be
used for an MMI device, a modem or
other devices with a serial interface.
Ethernet interface
The FEC Standard versions with an
Ethernet interface incorporate an
Ethernet 10BaseT interface with an
RJ45 connection and a data
transmission rate of 10 Mbits/s.
A combined “Link/Active” LED
indicates the connection status. The
FEC Standard supports data
communication and programming/
troubleshooting via the Ethernet
interface.
Programming
The FEC Standard is programmed
using FST.
FST is a unique programming
language rich in tradition and very
easy to use, allowing “programming
the way you think”:
IF ... THEN ... ELSE
FST also supports STEP operation for
sequence programming. FST can be
used for programming via Ethernet; a
web server is also available.
Power supply
The FEC Standard is powered
exclusively via 24 V DC as per modern
control cabinet technology.
24 V DC (+25%/-15%) power supply
for the controller itself,
24 V DC (+/–25%) power supply for
the input signals, positive switching,
24 V DC output signals 400 mA, proof
against short-circuits and low-
resistance loads.
The analogue inputs/outputs are
0(4) ... 20 mA I/Os, 12 bit resolution.

Controllers FEC, Standard
Key features
The sensor/actuator connector
Together with the FEC Standard, we
are introducing an innovative new
installation concept, the sensor/
actuator connector SAC. This
connector combines three functions
in a very compact design:
Electronic control systems
Front End Controllers
•
Connection of inputs, outputs and
power supply
•
Status signal by means of an LED
•
Replaces terminal strip for sensors
and actuators
The three-wire version of the
connector has internally connected
straps for 0 V and 24 V DC. This
allows any sensor (up to 3 wires) or
actuator (up to the maximum
permissible output current) to be fed
directly to the connector. There is no
need for a terminal strip for sensors
and actuators. This allows space
savings in control cabinets of up to
50%.
7.1
The SAC uses a tension-spring contact
system. This means no need for screw
connections. Solid wires can simply
be pushed into the connector, while
in the case of finely-stranded wire, all
that is necessary is to open the
contact by pressing on the relevant
pin and then introduce the wire.
Cable end sleeves can be used if
desired but are not essential. The
tension-spring system and the fact
that no terminal strip between the
controller and sensors/actuator is
required means that a time saving of
up to 40% can be achieved during
installation.
The pin assignment for the I/O panel
is simple and is always the same:
Pin 1
+24 V DC
Pin 2
Bit 0
Pin 3
Bit 1
Pin 4
Bit 2
Pin 5
Bit 3
Pin 6
Bit 4
Pin 7
Bit 5
Pin 8
Bit 6
Pin 9
Bit 7
Pin 10
0V
The power supply for the LEDs is
taken from the signal pins in the
connector. This means that the entire
input assignment can be checked
without a controller.

Programming the way you think
How do we describe a machine?
“When a workpiece reaches here, this
cylinder should advance.”
How does the software interpret this?
How, for example, can we sub-divide
a task?

How does one controller
communicate with another?
Every controller with Ethernet can
send and receive data from every
other controller within a network – no
matter whether this data relates to
inputs, outputs, flags or registers.
Central programming of distributed
controllers
Every controller within a network can
be programmed from any desired
network interface.
A controller on the World Wide Web
FST incorporates a web server – the
Internet and the world of automation
meet.

Or does your machine work through a
sequence step by step?
“First, this cylinder must advance and
stop the workpiece, and then the
workpiece must be clamped, and then
finally...”
