Actuators convert electrical signals such as commands from PLCs into mechanical motion or other physical variables and thereby actively engage in the process.
Bulk reading enables the simultaneous identification of multiple RFID-tagged objects. A particular protocol enables the individual addressing of tags.
Kanban helps reduce stocks of intermediate products by ensuring that only the quantities that are actually needed go into production. Once a container, box or bin has been used up, the Kanban card is sent as a signal to the source for production or refilling.
In the case of eKanban, all card movements and thus the goods in stock are automatically read by barcode or RFID scan. Kanban signals are thereby sent and processed automatically and in real time.
ERP – Enterprise Resource Planning
ERP systems are software solutions for planning and controlling enterprise resources such as machines, materials, personnel and capital.
RFID systems operate in various frequency ranges depending on the type of application:
Low frequency (LF)
30-500 kHz low range
High frequency (HF)
10-15 MHz medium range
Ultra-high frequency (UHF)
850-950 MHz long range
IoT – Internet of Things
IoT refers to the networking and communication between small devices as well as ‘smart objects’. M2M (machine-to-machine) communication aims to help supporting people in their work. IoT also stands for decentralisation as commands are not sent via a central server. They are exchanged directly between actors.
A mini-computer is a cost-efficient and high-performance computer system in which all the electronic components that are needed for its operation are stored on a single printed circuit board.
A middleware is an additional layer within a given software architecture. Its purpose is to simplify access mechanisms to sublevel layers.
For instance, ‘coNEO’ handles the provision of information from sublevel layers for assistance systems in your processes or triggers notifications in case of a discrepancy deviation ‘coNEO’ also manages the connection to ERP systems.
This thereby reduces the strain on application programs, increases productivity and optimises the production process.
NFC Reader – Near Field Communication
NFC readers are high frequency RFID scanners. Data is transmitted over very short distances. The employee thereby actively and directly triggers the reading of the transponder.
OPC-UA – Open Platform Communication - Unified Architecture
OPC-UA is a communication standard and an industrial M2M (machine-to-machine) protocol. It is able to not only transmit machine data, such as process or measurement values, but also semantically describe them so that they are legible to machines. OPC-UA is neutral with respect to the platform or operating system, and enables communication between all of the actors involved in production. It also provides safe and reliable data collection and transmission.
RFID – Radio Frequency Identification
RFID systems are sender-recipient systems that localise and identify objects by means of radio waves in an automatic and contactless manner. The system comprises a transponder (tag), which is furnished with an identification code, and a reader. If the transponder is scanned by the reader, this triggers two-way communication. This serves to transmit and store data in a contactless manner.
Sensors register various inputs and convert these into electrical signals. These are then processed into control commands (output) by PLCs program.
Shop floor management is a method of production organisation on the level of operations. The effective approach aims to ensure continuous process improvements by means of cooperation between employees and executives.
SmartShelf antennas are thin and light RFID antennas that are installed directly into shelving systems or POS (point of sale) applications. The intelligent bypass function allows up to 32 SmartShelf antennas to be interlinked per reader. In our eKANBAN applications they ensure the selective reading of different board sections.
PLC – Programmable Logic Controller
PLCs control industrial processes and ensure automation solutions. Sensor inputs are processed into control commands (outputs) in PLC programs that are then carried out by actuators.
Tags are small transponders that contain stored data and which transmit these to the RFID reader via radio waves. They are affixed to the object and hold writable memory. They contain a processor, memory and the send-and-receive device which matches to the RFID frequency depending on the type of application. The memory capacity can range from 8 bytes to 8 KB. Visual contact with the reader is not necessary.
UHF – Ultra-High Frequency
UHF readers are ultra-high frequency scanners which ensure a long scan range. They are predominantly used in automated goods distribution. In contrast to NFC readers, they are able to read a larger volume of tags (bulk reading) simultaneously and not just one-by-one.
