Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

1.1 Product description
The Extension Unit is used to install additional operator controls (installation components)
below a 16:9 SIMATIC PRO device for pedestal (extendable, flange bottom) or for support
arm (extendable, round tube). The Extension Unit for SIMATIC PRO devices ③is available
in two different basic versions (see figure below):
●Extension Unit Standard④for
–Standard operator controls, such as illuminated pushbuttons, emergency stop buttons
and interface components that are individually wired.
–The Extension Unit Standard is usually delivered without operator controls.
–The Extension Unit Standard is also available as a customized version.
●Extension Unit Advanced⑤for
–Advanced operator controls, such as RGB illuminated pushbuttons, that are
connected through an internal bus.
–Standard operator controls, such as illuminated pushbuttons, emergency stop buttons
and interface components that are individually wired.
–The Extension Unit Advanced is pre-configured by the customer, ordered individually
and delivered pre-assembled with installation components.
●Customers can retrofit the Extension Units themselves, for example, with standard
operator controls.
The figure below shows an example of two Extension Units 22" for support arm mounting ①
and ②.

1.1.1 Extension Unit Standard
The example in the figure below shows the Extension Unit 22" with eight operator controls
including emergency stop button.
Device variants
The Extension Unit is supplied without operator controls; the available slots are suitable for
installation of operator controls. The Extension Unit is available in the following versions that
differ in width and number of slots:
●Extension Unit 12" with 6 slots

KP12 performance features
The KP12 HMI device displays the operating states of 12 separated elements of a plant via
the color and brightness of its 12 pushbuttons.
Based on this, you can use the 12 pushbuttons to operate an ongoing production process.
●12 short-stroke keys with integrated LEDs
The LEDs allow the display of different colors: Red, green, blue, yellow and white can
only be set in runtime.
The common brightness of all LEDs can be adjusted individually for each KP12.
●Communication via PROFINET
●Configuration via TIA Portal
●SIMATIC design
Through this, the HMI devices can be arranged closely next to each other.
Logs
The KP12 uses the following protocol to communicate with the controller:
●PROFINET IO for standard communication
Note
Safety-related communication
A SIMATIC
S7F fail-safe controller is required for safety-related communication.

Example of an Extension Unit 22" with 7 standard operator controls and one emergency stop
button. The other slots are indicated by dotted lines.
For the Extension Unit Hardwired, Lxmarks the slot positions on the left as counted from the
center while Rxmarks the slots on the right.
With Extension Unit PROFINET and Extension Unit PROFIsafe, the slots are numbered
similar to the display in the TIA Portal in ascending order from left to right. The numbering in
this and the following figure corresponds to STEP 7 (TIA Portal) V15; for V14, the numbering
of the slots from 1 to 12 applies.

1.3.3 Advanced operator controls and interfaces
The figures below show the terminal designations (slot numbers) for the Advanced
installation components and their wiring.
Front
Example of Extension Unit 22", minimum configuration: 1 × KP12 and 8 additional slots. In
the figure, 3 RGB illuminated pushbuttons are installed and the other operator controls are
marked with dashed lines. An RFID reader can be installed on the left and right in each case
(dashed rectangles, see section "Extension Unit Advanced (Page 12)").
When the KP12 and the 8 RGB illuminated pushbuttons (dashed circles) are cabled one
after the other from left to right, their slot numbers are also sequentially numbered from 14
(left) to 22 (right).
Note
Connection sequence, slot number 14
The order in which the connection cables are inserted (connection sequence, see rear panel)
determines the slot number. The first Advanced installation component connected to the
internal bus always has slot number 14, becau
se the first 13 numbers are reserved for the
Standard installation components and the communication module.
•
The
second
Advanced installation component connected to slot number 14 has slot
number
15
,
regardless
of its mounting position.
In contrast, the ter
minal designations for an Extension Unit Standard
depend
on the
mounting position:
•
The Standard installation component at the
second
mounting position always has the
number "
2
".
Standard operator controls can be installed in the Extension Unit Advanced in
parallel, if the
corresponding mounting positions are free.

You can find a description of the interfaces of the respective communication module in the
connection compartment of the Extension Unit in the section "Technical specifications
(Page 81)".
