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.
