Contrinex: RFID read/write modules with IO-Link

by donpedro

New library simplifies programming
With RFID technology, no line of sight is required to read or write transponder data. For users, however, programming the read/write modules can be relatively time consuming. With the function block library from Contrinex, this engineering cost has now been significantly reduced.
RFID technology has proved itself in automation and logistics over recent years. Unlike classical identification systems, such as barcode or laser marking, RFID transponder data can be read or written with no line of sight required. In addition, data can be added, changed or replaced. However, the programming work with RFID read/write modules should not be underestimated. To help reduce such engineering costs, Contrinex provides a solution in the form of a function block library for IO-Link. The IO-Link library covers all necessary functions for communication with a Simatic S7-1200 / S7-1500 or equivalent PLC. The user can drag and drop the required IO-Link function block into the corresponding network and store it there. All IO-Link function blocks for high-frequency read/write modules can be downloaded free of charge from the website of this sensor specialist.

Connecting two standards within Industry 4.0
Contrinex offers a wide range of RFID read/write modules. For example, the 13.56 MHz high-frequency portfolio includes two cylindrical devices with an IO-Link interface: RLS-1181-320 (M18) and RLS-1301-320 (M30). These read/write modules combine two communication standards that are important for Industry 4.0: ISO 15693 at the air interface and IEC 61131-9 at the M12 connector. For signal transmission, they offer a standard IO (SIO) mode and an IO-Link mode. In SIO mode, conditional binary outputs are set at the device interface, such as tag detection or data-block comparison. In IO-Link mode, the commands “scan UID”, “scan user data” and “scan read/write command” are available as process data. These smart sensors provide read/write distances of 42 mm (M18) and 60 mm (M30), work reliably even when dirty and operate across a wide temperature range from -25 to +80°C (-13 to +176°F). Their metal housings are highly robust with an enclosure rating of IP67.
