SIMATIC HMI Key Panels
The innovative operator panels for up to 60% time savings
during installation
SIMATIC HMI Key Panels replace conventional operator
panels. They are compact and pre-assembled ready-to-
install, but significantly more cost-effective. Thus up to
60% time savings can be achieved during installation.
Key Panels KP8, KP8F, and KP32F
Key Panels are operator panels with large keys with LED back-
lighting. The user can set five colors (blue, green, red, yellow,
white) and the brightness of the keys via the STEP 7 hardware
configuration. The keys can be easily and individually labeled
using slide-in labels and feature tactile feedback. Thus they
can be reliably operated even when wearing gloves.
The KP8 is available in two versions: The standard version KP8
and the device with failsafe functionality (KP8F). Both devices
have 8 digital inputs/outputs for the direct connection of sen-
sors and actuators. The KP32F has 32 keys and provides 16
digital inputs/outputs and an additional 16 digital outputs,
non-isolated.
Communication options
The connection to the controller is made via PROFINET.
A 2-port Ethernet switch permits the configuration of linear
and ring topologies.
The SIMATIC HMI Key Panels have a redundancy mechanism,
which allows you to bridge any faults that may occur. By
means of the Media Redundancy Protocol (MRP) for networks
in a ring topology, a cable break or component failure is com-
pensated for by means of a switch that opens a second com-
munication path through the network. In the event of a data
cable failure, the communication is diverted to this alternative
path in real time, thus guaranteeing continuous and reliable
communication among the components.
Ideal expansion for fully enclosed HMI devices
The format of the KP8/KP8F is selected so that it is also ideally
suited for installation into the expansion units of the fully en-
closed HMI devices (see page 20). On the front, the Key Panels
achieve degree of protection IP65.
Fail-safe versions
With the help of the integrated PROFIsafe communication, the
KP8F and the KP32F can be used for fail-safe operation with
SIMATIC S7-300F/400F for simple emergency stop applica-
tions. The two additional fail-safe, 24 V-capable digital inputs
of the KP8F can be used for sensors with isolated contacts,
e.g. an SIL 3 emergency stop button.
The KP32F has 4 fail-safe, 24 V-capable digital inputs for sen-
sors with isolated contacts.
