109283-01-04/10 Subject to technical modifications Page 5/44
Manual EKS Electronic-Key Adapter PROFINET

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 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:
f The 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.
3.1.2). In this case, a safe evaluation device must be connected downstream. This means that the
f The 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.
f The user must select the related operating mode using the control system or another suitable circuit.
f The 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.:
f EN 60204, Safety of machinery. Electrical equipment of machines
f EN 12100-1, Safety of machinery. Basic concepts, general principles for design - part 1: basic terminology,
methodology
f EN 62061, Safety of machinery. Functional safety of safety-related electrical, electronic and programmable
electronic control systems
f 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 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
The Electronic-Key adapter must only be employed and used in accordance with
f this manual and
f other documentation referred to in this manual.
The EKS Electronic-Key adapter is not a safety component in the sense of the machinery directive.
Without additional precautions the EKS Electronic-Key adapter must not be used to provide a safety function, particularly if failure or malfunction of the unit 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.

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:
f Electronic-Key
f Electronic-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.
109283-01-04/10 Subject to technical modifications Page 9/44
Manual EKS Electronic-Key Adapter PROFINET
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:
f 116 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).

Manual EKS Electronic-Key Adapter PROFINET

6.1 Connection PROFINET

The interface for the Electronic-Key adapter is compatible with the standards ISO/IEC 61754-24 and IEC 61158. The Electronic-Key adapter is operated in full-duplex mode with 10 MBit/s or 100 MBit/s.
Information!
f Only a screened 100 BaseTX cable, twisted pair, Cat 5 or higher, is permitted for use as the
connection cable. The maximum cable length is 100 m.
f It may be necessary to provide additional screening in conditions with a high level of EMC
interference.
f For the PROFINET connection a separate switch may be required.

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:
f Reset to default IP address (see sections
f Permit 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
3. Apply power supply. Wait until the Electronic-Key adapter has applied the default IP address. This situation is indicated by red/green flashing.
4.4.3 and 6.1.1.1)
4.4.3) to ON.
4. Disconnect Electronic-Key adapter from the power supply. Set DIP switch S3.3 to OFF (see DIP switch settings in section
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.

f A power supply of suitable EMC performance must be used for the power supply.
f Conductor cross-section maximum 1.5 mm².
f Tighten 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:
f It 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.
f The 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
f Integrate the EKS FSA as defined in the following connection examples from EUCHNER.

6.4.1 Connection example with enabling switch

Figure 3: Principle of operation (illustration with selected operating mode and all components in actuated position)
6.4.1.1 Description of the application example with enabling switch
The danger area on a machine is secured with a fence. To allow set-up work on the machine with the guard open, an EKS FSA system is integrated in conjunction with a control system, an enabling switch and a safety relay. The safety relay must comply with the following requirements:
f Detection of short-circuits and earth faults. A short-circuit can be detected in the safety path in the circuit
described due to the fact that both the positive path and earth path of the safety relay are switched. In this case, the safety relay deactivates its safety outputs.
f Simultaneity monitoring: the safety relay must detect whether the safety inputs are switched practically
simultaneously. If this is not the case, the safety outputs are not switched and the unit switches to fault state. A renewed start is possible only after the enabling switch has been released and then operated again.
The switching contact LA1/LA2 is closed after insertion of the Electronic-Key. The EKS FSA is coupled with a control system. After the insertion of the electronic key, the PC checks whether the key is authorized for work in the selected operating mode. If this is not the case, the operating mode cannot be set. If suitable access rights are available, the control system gives the instruction to the switching contact A100.0 to close.

Manual EKS Electronic-Key Adapter PROFINET
The switching contact LA1/LA2 is connected to the first input on the safety relay in series with a switching contact on the enabling switch. The switching contact A100.0 is connected to the second input on the safety relay in series with the second switching contact on the enabling switch. The result is that these inputs on the safety relay are only enabled if
f the EKS-FSA (switching contact LA1/LA2) and
f the control system (switching contact A100.0) issue the related enabling signal and
f the enabling switch is actuated.
The output contacts on the safety relay are enabled only after actuation of the enabling switch.
The safety relay is de-energized without a time delay (stop category 0) and the machine movement is stopped if
f the Electronic-Key is removed or
f the enabling switch is released or
f the machine control system cancels the enable state (contact A100.0 is opened).
Note: The control system output A100.0 may be set only
f if the corresponding Electronic-Key is inserted and
f a suitable operating mode is selected.
6.4.1.2 Feedback loop
The safety relay can be started only with the feedback loop closed. A welded contactor contact in the enable path will thus be detected when a start request is made and a start is then prevented. The power contactor must have positively driven contacts.
6.4.1.3 Start
The safety relay start takes place after enabling by the EKS FSA and by the control and after operation of the enabling switch.

8 Operation in the PROFINET

8.1 Communication

This section primarily describes communication between a PC and Electronic-Key adapter (referred to as the device in the following). The communication between the control system and the device is either cyclic (write / read processes to and from the Electronic-Key) or acyclic (diagnostic messages).

8.2 EKS alarms

Depending on the setting in the configuration, the EKS can send
f Diagnostics alarms
f Process alarms
f No alarms
to the control system (see section
7.2 Configuration settings). Process alarms are written to a data area in the control system. The alarms have the following structure: [byte word with alarm no.];[byte with alarm information]
Example
During an attempt to read the serial number of the Electronic-Key, byte no. 116 is entered as the start byte and 20 bytes as the number of bytes to be read. However, in this case the maximum possible number of bytes is 8. Description: Error during read access. Max. number of bytes allowed incorrect. Depiction in the related data area in the control system: 0100;08

Manual EKS Electronic-Key Adapter PROFINET

8.3 Read/write operation

In read or write operation, following successful configuration, a transfer message with up to 128 bytes is continually transferred to the input area or the output area of the control system during each cycle.
Information!
On the Electronic-Key read/write with 116 bytes freely programmable, the memory is organized in 4­byte blocks. This means the start address must be given in the range byte number 0 to byte number 112, always in 4-byte steps (byte number 0, 4, 8 ... 112). Also the blocks written must always be a multiple of 4-byte blocks (4, 8, 12 ... 116 bytes)!
However, during reading it is possible to access the memory byte-by-byte without the above-mentioned restriction for writing.
The Electronic-Key read/write also contains a unique 8-byte serial number. This number is written by laser during the electronic key production process and can never be changed or deleted. The serial number can therefore not be changed. The serial number is used for secure distinction of every single Electronic-Key. It is necessary that all 8 bytes are completely evaluated for reliable differentiation. The serial number is appended to the freely programmable memory. The serial number can be read by entering the start address byte number 116 and the number of bytes 8.

8.3.1 Input area (read process)

Information!
If a specific start address is not defined, the user data are cyclically transferred to the input area of the control system from byte no. 0 on the Electronic-Key. The number of bytes with user data transferred cyclically from the Electronic-Key depends on the setting in the configuration software for the control system (see section
7.2.1.2 Parameter Start address and 7.2.1.3 Parameter Number of bytes).

8.3.2 Output area (write process)

Information!
When this command is used, the Electronic-Key must be in the Electronic-Key adapter, and must be removed from within the operating distance only after the reply message has been received. As the serial number of the Electronic-Key cannot be written, the start address for the data to be written is limited to byte no. 0 to byte no. 112.

9 Analysis and Assignment of DCP Name via Web Interface

As an alternative to communication via PROFINET, it is possible to communicate with the EKS Electronic-Key adapter from a PC with the aid of web browser via TCP/IP. The feature can be used, e.g., for analysis, to read data from the memory in the Electronic-Key and to display them in the browser. The DCP name for the Electronic-Key adapter can also be set via the web browser (see also DIP switch settings in section 4.4.3). This process is described in detail in the following sections.

9.1 Network settings for a configuration PC with Windows® XP

Information!
f It is assumed that you connect the PC to the EKS Electronic-Key adapter as shown in the following
example.
f For connection, you need a (Cat 5) patch cable with crossed cables (crossover).
f You must first modify the network settings on the PC so that the web interface can be opened.
f Enter IP address for the PC from 192.168.1.2 to 192.168.1.254.
