1.4 Correct use
As part of a higher-level overall system, the EKS read/write station is used for access control and monitoring on
control systems or parts of control systems for machine installations. EKS can be used, for example, as part of
an overall system for checking access rights on the selection of the operating mode. However, it is not permitted
to derive the operating mode directly from the access rights on the Electronic-Key. If the selection of the
operating mode is relevant for safety, this must not be performed by means of the EKS; instead an additional
device must be used to select the operating mode.
Information!
The Machinery Directive 2006/42/EC provides
information on selection of the operating mode. It is
imperative that this information be followed.
When designing machines and using the read/write station, the national and international regulations and
standards specific to the application must be observed, e.g.:
EN 60204, Safety of machinery – Electrical equipment of machines
EN 12100-1, Safety of machinery – Basic concepts, general principles for design – Part 1: Basic
terminology, methodology
EN 62061, Safety of machinery – Functional safety of safety-related electrical, electronic and programmable
electronic control systems
EN ISO 13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles
for design
Modifications to the electronics of the read/write station and any other changes, especially mechanical
modifications and reworking, are not permissible and will result in the loss of the warranty and exclusion of
liability.

Manual EKS Ethernet TCP/IP
2547185-01-10/22 Subject to technical modifications Page 7/38
The read/write station must be employed and used only in accordance with
this manual and
other documentation referred to in this manual.
The EKS read/write station is not a safety component in the sense of the Machinery Directive.
Without additional precautions the EKS read/write station must not be used to provide a safety function,
particularly if failure or malfunction of the device could endanger the safety or health of people in the operating
area of a machine.
1.5 Obligations on the operating organization
The manufacturer and the organization operating the higher-level overall system, e.g. a machine installation, are
responsible for the observance of national and international safety and accident prevention regulations
applicable in the specific case.

Manual EKS Ethernet TCP/IP
Page 8/38 Subject to technical modifications 2547185-01-10/22
2 Safety precautions
Warning!
The
EKS read/write station is not a safety component in the sense of the Machinery Directive.
Without additional precautions the
read/write station must not be used to provide a safety function,
particularly if failure or malfunction of the device could endan
ger the safety or health of people in the
operating area of a machine. On this topic, pay particular attention to the sections
Correct use (see

3 Function
3.1 Functional description
3.1.1 Common functions of EKS Standard and version EKS FSA
The EKS is used for access control and monitoring on control systems or parts of control systems for machine
installations.
Instead of passwords, coded Electronic-Keys are assigned. In this way unauthorized access to control and
visualization systems is prevented to the greatest possible extent.
The EKS uses a non-contact, inductive read/write identification system.
It comprises:
Electronic-Key
Electronic-Key adapter EKS compact or Electronic-Key adapter FHM with interface adapter EKS modular
The user is responsible for organizing the programming of the application, integration into an overall system and
the assignment and use of the freely programmable memory in the Electronic-Key.
Information!
For easier organization and management of your Electronic
-
Keys and the data they contain, EUCHNER
also offers the Electronic
-Key-Manager EKM software. To enter data in the EKM software, an
Electronic
-Key adapter with serial interface or USB interface must be in operation on the PC.
EKS Ethernet TCP/IP devices are read/write systems with electronics for the inductive bidirectional interface to
the transponder and interface electronics.
Due to the non-contact transfer of data, the Electronic-Key adapter is designed with a high degree of protection
suitable for industry from the access side. The Electronic-Key adapter is fastened from the rear side of the panel
in order to exclude unauthorized tampering from the operator side.
The system is connected via the Ethernet TCP/IP interface, which is designed as an RJ45 socket. A separate
switch may be required for the Ethernet TCP/IP connection. The device does not have an integrated switch.
Setup and system integration can be implemented straightforwardly and quickly on the read/write station with
Ethernet TCP/IP interface.
The current state of the Electronic-Key adapter is displayed using a 3-color LED.
The Electronic-Key is placed on the Electronic-Key adapter for operation. The power supply for the transponder
and the data are transferred between the Electronic-Key adapter and the Electronic-Key without using any
contacts.
Figure 1: Cut-away illustration of an Electronic-Key adapter with Electronic-Key in the compact version

Manual EKS Ethernet TCP/IP
Page 10/38 Subject to technical modifications 2547185-01-10/22
Figure 2: Illustration of an Electronic-Key adapter with Electronic-Key in the modular version
The Electronic-Keys are tag shaped. The complete transponder with memory chip and antenna is integrated
into the Electronic-Key. The transponder does not have a battery.
The data carrier in the Electronic-Key is equipped with a combined memory:
116 bytes E2PROM (programmable) plus 8 bytes ROM (serial number)
The programmable memory of 116 bytes is organized in 4-byte blocks. This means a multiple of 4-byte-sized
blocks must always be written.
3.1.2 Additional functions of the version EKS FSA
The version EKS FSA has additional switching contacts (semiconductor relay) that are switched off as long as
there is no Electronic-Key in the Electronic-Key adapter or if the Electronic-Key cannot be read.
Device in compact version: switching contacts LA1/LA2 and optionally LB1/LB2
Modular version of the device: only switching contact LA1/LA2
The switching contacts are electrically isolated from the device electronics and from each other. Either AC or
DC can be switched.
Each of the contacts is operated with diversity by a dedicated processor that opens the contacts on removal of
the Electronic-Key (see figure Block diagram EKS FSA).
Figure 3: Block diagram EKS FSA
Due to separate evaluation of channel LA and channel LB, the EKS FSA device can be used in conjunction with
a safe evaluation device in safety-related applications. Integrated voltage monitoring switches off the switching
contacts LA and LB if the power supply is outside the permitted tolerance (see chapters 4.4 and 4.5).
Information!
The switching contacts
FSA close when the Electronic-
Key is in place, irrespective of the data allocation
in the memory.

Information!
Using the DIP switch S2, it is possible to set an EKS name that is used for addressing the device in the
network in conjunction with a DHCP server. This name consists of the fixed code EKS plus a
configurable number between 001 and 255 that ca
n be used in all system environments with DHCP
support. The station name for a specific
read/write station would then be EKS027, for example.
The DIP switch S2 is relevant specifically in conjunction with the Siemens SINUMERIK DHCP address
assignment routi
ne (see chapter 6.1.1.3 Operation in the Siemens system network).
In this way it is possible to set the identical address by copying the DIP switch settings if a device is
replaced.

Information!
The use of the DIP switches to assign the IP address is described in the following in chapter
6.1.1.
To prevent unauthorized changes to the network, it is sensible to deactivate the web interface after use.
For this purpose switch S3.1 is set to ON.

4.8 Indicator LED of compact version
The Electronic-Key adapter operating states are indicated using a three-color LED on the front.
The illumination of the LED in any color indicates the presence of the operating voltage.

Description
Color
Electronic-Key
adapter power-up
or fault
After the application of the power supply, the LED is constantly illuminated red
during power-up. The completion of the process is indicated by a change in this
state after approx. 10 seconds. If the LED then flashes red quickly, it is an indication
of a network fault.

4.9 Indicator LEDs of modular version
The operating states of the read/write stations are indicated via LEDs in three colors.
On the FHM Electronic-Key adapter, the state of the identification system is signaled by a single three-color
LED. On the interface adapter, the same state is signaled by three individual LEDs (read head) in different
colors. The illumination of the LED in any color indicates the presence of the operating voltage.
The state of the data interface is additionally signaled via two individual LEDs in different colors on the interface
adapter (Ethernet TCP/IP).
