Schlegel offers the following three RFID systems
Depending on the version, the RFID systems support the following operating modes: Cyclic and/or single reading. Cyclic reading means that the presence of the transponder is permanently being checked at regular intervals. As long as the transponder is registered, the function activated with the transponder remains active. Single reading means that each new registration of a transponder is being evaluated and that the assigned action is being activated.

RFID SKS - for a quick and easy integration in fields with only few requirements
RFID TMS - for a flexible application in fields with complex requirements

What is RFID Standard?
RFID Standard is a flexible, freely configurable system. With the help of commands the reading/writing unit can be programmed via an external control (PLC or industrial PC) with USB or RS232 connection according to one's own needs. The user can freely define the data structure on the transponder and evaluate it via the external control according to the requirements.
What is RFID SKS?
RFID SKS is an independent RFID system which is designed for a simple and fast integration into existing operating environments. It does not require special connections like e.g. USB or RS232 and the outputs can be accessed directly. The system consists of a reader, an evaluation electronics, a master key (admin transponder) and the user keys (user transponder). Reader, evaluation electronics and master key are components that are assigned to each other. The reader can only communicate with the appropriate evaluation electronics and the system can only be set up with the appropriate master key.
TCA: Transponder-Collector-Assignment. The data of the transponder is assigned to the open collector outputs. Learn more about the SKS-TCA (Link instructions SKS-TCA).
TRA: Transponder-Relais-Assignment. The data of the transponder is assigned to the potential-free relay outputs of the SKS. Learn more about the SKS-TRA (Link instructions SKS-TRA).
What is RFID TMS?
In its structure, RFID TMS is quite similar to the SKS system. In addition it includes a software in order to manage the transponders. Different to the SKS the information is stored in the transponder. The software is absolutely necessary for programming the transponders. The software is created with a customer-specific serial number which is saved when the transponders are programmed. The transponders can only be processed by the evaluation electronics having the same serial number. This ensures that no functions can be activated by external transponders. In addition to the serial number there are two other sectors on the transponder on which the customer can save data with the software.
TRA: Transponder-Relais-Assignment. The data of the transponder is assigned to the potential-free relay outputs of the TMS. Learn more about the TMS-TRA (Link instructions TMS-TRA).
TCA: Transponder-Collector-Assignment. Die Informationen des Transponders werden auf Open-Collector-Ausgängen des TMS abgebildet. Learn more about TMS-TCA (Link instructions TMS-TCA).

FAQ
What is RFID?
RFID stands for Radio Frequency Identification and describes the contactless identification of objects via radio waves. An RFID system always consists of a reading unit and one or more transponders (so-called tag).
How does the setup of an RFID system look like?
The transponder consists of a coil (antenna) and a microchip that carries the data. The reading device generates an electromagnetic field via radio waves. If there is a transponder present within this field, its coil induces electricity and creates a signal, which the reading device can receive and analyse.
How are RFID systems used?
A typical field of application for RFID is the identification of people, e.g. access controls or time recordings. But also identification of objects, e.g. in relation to authenticity checks, maintenance or production, is often realised by using RFID.
Which RFID technologies are there?
RFID is available for various frequencies. To put it simple, the longer the required range, the more energy is needed. There is a distinction between three frequency ranges: LF (low) covers areas of < 135 KHz and < 0.1 m, HF (high) covers areas of 13.56 MHz and < 0.5 m, UHF (ultra high) covers areas of 865 – 928 MHz and < 10 m.
