The EKS Electronic-Key adapters with PROFINET interface conform to the EMC directive 2004/108/EG
(2004/108/EC, 2004/108/CE).
The Electronic-Key adapters comply with the following European / international standards:
fEN 61000-6-2: 2005 Electromagnetic compatibility (EMC). Generic standards -
Immunity for industrial environments
fEN 55011:2007 + A2:2007 (ISM) Industrial, scientific and medical (ISM) radio-frequency
equipment - Radio disturbance characteristics - Limits and methods of measurement
1.3 Approvals
The EKS Electronic-Key adapters with PROFINET interface are certified in accordance with (UL file
number E240367).
For use and operation as per the requirements, a power supply for use in class 2 circuits must be used.

Manual EKS Electronic-Key Adapter PROFINET
Seite 6/44 Subject to technical modifications 109283-01-04/10
1.4 Correct use
As part of a higher-level overall system, the EKS Electronic-Key adapter is used for access control and
monitoring on controllers or parts of controllers for machine installations. EKS can be used, for example, as part
of an overall system for checking access rights for operating mode selection. However, it is not permitted to
directly derive the operating mode from the access rights on the Electronic-Key. If the selection of the operating
mode is relevant for safety, this action must not be performed by means of the EKS; instead an additional
device must be used for selection of the operating mode. This is possible via the graphical user interface on the
control system, for example.
The version EKS FSA has outputs that can be utilized to produce a safe shut-down signal (for block diagram
see section 3.1.2). In this case, a safe evaluation device must be connected downstream. This means that the
EKS FSA can be used for safety-relevant applications. The machine must be reset to a safe operating mode
when the Electronic-Key is removed. A hazard analysis must be performed on this aspect as per the
requirements in the machinery directive. The risk and the necessary risk reduction by technical means must be
determined with reference to a suitable standard. The following requirements must be met for operation:
fThe data signal (channel LB) and the switched output LA1/LA2 (channel LA) must be polled by a safe
downstream evaluation device corresponding to the risk determined. The data line (channel LB) is used to
supply the information as to whether or not an Electronic-Key is inserted and which access rights are
assigned to the Electronic-Key. The output LA1/LA2 (channel LA) is used for redundant supply of the
information as to whether or not an Electronic-Key is inserted (independent of the access rights). The data
line or, alternatively, the switched output LB1/LB2 can be used as channel LB. Like LA1/LA2, the output
LB1/LB2 is used to supply only the information as to whether or not an Electronic-Key is inserted
(independent of the access rights). Use of the output LB1/LB2 is optional.
fThe control system must check whether the Electronic-Key inserted is authorized to select the operating
mode and whether the access rights on the Electronic-Key permit operation in the operating mode currently
selected.
fThe user must select the related operating mode using the control system or another suitable circuit.
fThe manufacturer of the system must check which safety level is reached with the overall system and
whether the overall system provides adequate safety against hazards in the intended application.
Information!
The machinery directive 98/37/EC provides information on selection of the operating mode. It is
imperative this information is followed.
When designing machines and using the Electronic-Key adapter, the national and international regulations and
standards specific to the application must be observed, e.g.:
fEN 60204, Safety of machinery. Electrical equipment of machines
fEN 12100-1, Safety of machinery. Basic concepts, general principles for design - part 1: basic terminology,
methodology
fEN 62061, Safety of machinery. Functional safety of safety-related electrical, electronic and programmable
electronic control systems
fEN ISO 13849-1, Safety of machinery. Safety related parts of control systems - part 1: General principles for
design
Modifications to the electronics of the Electronic-Key adapter 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 Electronic-Key Adapter PROFINET
109283-01-04/10 Subject to technical modifications Page 7/44

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 controllers or parts of controllers for machine
installations.
Instead of passwords, coded Electronic-Keys are assigned. In this way unauthorized access to control and
display systems is prevented to the greatest possible extent.
The EKS uses a non-contact, inductive read/write identification system.
It comprises:
fElectronic-Key
fElectronic-Key adapter
The user is responsible for organizing the programming of the application, integration in 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.
The Electronic-Key adapter is a read/write system with integrated evaluation electronics and interface.
Thanks to the use of data transfer without using any contacts, the Electronic-Key adapter has the high degree of
protection of IP 67 from the access side, i.e. it is suitable for industrial use. The Electronic-Key adapter can be
installed in accordance with DIN 43700 in any control panel with a standard cut-out of 33 mm x 68 mm. The
Electronic-Key adapter is fastened by means of screw clamp elements from the rear side of the panel in order to
exclude unauthorized manipulation from the operator side.
The system is connected via the integrated PROFINET interface that is designed as an RJ45 socket. For the
PROFINET connection a separate switch may be required. The device does not have an integrated switch.
Setup and system integration can be realized straightforwardly and quickly on the Electronic-Key adapter with
PROFINET interface.
The current state of the Electronic-Key adapter is displayed using a 3-color LED.
The Electronic-Keys are tag-shaped. The complete transponder without batteries with memory chip and
antenna is integrated into the Electronic-Key.

Manual EKS Electronic-Key Adapter PROFINET
Seite 10/44 Subject to technical modifications 109283-01-04/10
For operation, the Electronic-Key is inserted in the Electronic-Key adapter and is held in place by a spring clip.
The power supply for the transponder and the data are transferred without using any contacts between the
Electronic-Key adapter and Electronic-Key.
Figure 1: Cut-away illustration of Electronic-Key adapter
The data carrier in the Electronic-Key is equipped with a combined memory:
f116 bytes E²PROM (programmable) plus 8 bytes ROM (serial number)
On Electronic-Keys read/write with 116 bytes, the memory 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 two additional semiconductor relay outputs (LA1/LA2 and optionally LB1/LB2) that
are switched off as long as there is no Electronic-Key in the Electronic-Key adapter or if it is not possible to read
the Electronic-Key.
The semiconductor relay outputs are electrically isolated from the device electronics and from each other. Either
AC or DC can be switched.
Each of the outputs is operated with diversity by a dedicated processor that switches off the outputs on removal
of the Electronic-Key (see Figure Block diagram EKS FSA).
Figure 2: Block diagram EKS FSA
By separately evaluating 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 section 4.2).

6.1.1 PROFINET Configuration
It is necessary to assign a unique DCP name and a unique IP address for the unambiguous addressing of a
subscriber in the PROFINET network. The DCP name EKS-PN is saved in the device as the factory setting.
In the first step a DCP name is assigned to the Electronic-Key adapter (see DIP switch settings in section 4.4).
There exist the following three possibilities:
1. Assignment via the configuration software
2. Assignment via setting of DIP switch S2
3. Assignment via web interface
This DCP name is saved in the Electronic-Key adapter. In the second step the IP is always set automatically via
the configuration software based on the unique DCP name used and assigned via the DCP CPU.
In addition, the following service functions can be set with DIP switch S3:
fReset to default IP address (see sections 4.4.3 and 6.1.1.1)
fPermit or prohibit configuration via web interface (see sections 4.4.3 and 9.2)
The individual functions are described below in detail.
6.1.1.1 Default IP address
Every Electronic-Key adapter has the factory-set default IP address 192.168.1.1 and the subnet mask
255.255.255.0.
To reset the Electronic-Key adapter to the default IP address, proceed as follows. The Electronic-Key adapter
must be disconnected from the PROFINET network during this routine.
1. Disconnect Electronic-Key adapter from the power supply.
2. Set DIP switch S3.1, S3.3 and S3.4 (see DIP switch settings in section 4.4.3) to ON.
3. Apply power supply. Wait until the Electronic-Key adapter has applied the default IP address. This situation
is indicated by red/green flashing.
4. Disconnect Electronic-Key adapter from the power supply. Set DIP switch S3.3 to OFF (see DIP switch
settings in section 4.4.3).
After the application of the power supply, the Electronic-Key adapter now powers up again with the default IP
address. The DCP name is deleted during this process.
6.1.1.2 Setting DCP name via DIP switch S2
In this operating mode the DCP name for the EKS is defined by the DIP switch S2. During this process DIP
switch S2 defines the suffix for the DCP name EKS-PN-XXX, where XXX can have the values 001 – 255. A
prerequisite for this operating mode is that during configuration the DCP name EKS-PN-XXX is used.

Information!
With this setting it is also possible to easily change an EKS in case of need for replacement. For this
purpose the suffix number for the old EKS is set on the new EKS via DIP switch S2 and the new EKS
then fitted.
6.2 Connection of power supply
(For information on pin assignment see section 4.3.2 Plug-in screw terminals for power supply )
It is imperative that the following points are observed:
fThe connections must be made as appropriate to maintain EMC performance.
fA power supply of suitable EMC performance must be used for the power supply.
fConductor cross-section maximum 1.5 mm².
fTighten the terminal screws on the plug to 0.22 Nm.
6.3 Connection of function earth
The function earth is connected via terminal 3 on the plug-in screw terminals for the power supply. This
connection is electrically connected internally to the housing of the Electronic-Key adapter.
Information!
The function earth must be connected to PE!
6.4 Connection of the switched outputs (for EKS FSA only)
Warning!
Incorrect connection or errors in the safety-related integration of the EKS FSA can lead to fatal injury.
For this reason, observe the following safety aspects:
fIt is not possible to generate a safe signal by using only the switched outputs LA1/LA2 and
LB1/LB2. Safe, downstream evaluation is always necessary (e. g. using a safety relay). Use of the
switched output LB1/LB2 as an alternative to the data line is optional.
fThe safe evaluation must always be dual-channel. For this purpose, there are two alternatives:
1. Evaluation of output LA1/LA2 as channel LA together with an evaluation of the data line as
channel LB (recommended)
2. Evaluation of output LA1/LA2 as channel LA together with the output LB1/LB2 as channel LB
fIntegrate the EKS FSA as defined in the following connection examples from EUCHNER.
