n TECHNOLOGY PILZ HAS LAUNCHED an IO-Link Safety master for rapid commissioning of modular, decentralised production plants. The PDP67 master is one of the first devices to comply with the IO-Link Safety specification v1.1.4, which has recently been certified by TUV SUD (see page 38). It can be used to implement bidirectional communications up to the field level. The device extends the functions of a conventional IO-Link master by adding the option for safe communications for functional safety. As a decentralised interface to higher-level safety controllers, it enables various connections, such as safety sensors with IO-Link Safety, or standard IOLink sensors or actuators. It provides flexible, safe communications up to PLe / SIL3, whether it's safety-related or standard communications. The master has four IO-Link Safety ports (Class A), plus four other ports, each with two configurable safe digital inputs or outputs. Sensors and actuators can share the same connection. As a result, users can make their designs more flexible, and expand them. As a decentralised interface to higher-level safety controllers, the new master can process IO-Link Safety and failsafe signals, as well as IO-Link and standard signals. In addition, classic safety sensors – with OSSD outputs, for example – or actuators, can be connected at field level. The master can therefore be used to implement modular plant concepts. Plug-and-play operation using standard M12 plug-in connectors reduces cabling. Applications can be configured and commissioned via a built-in Web server, through which errors can also be diagnosed rapidly, reducing commissioning times and downtime at the field level. The safety master has IP67 or IP69 protection and can be used directly on a machine, or in rugged environments up to 5km above sea level and in temperatures from –30°C to +70°C. It is said to provide reliable safety in industrial or outdoor environments, and in dirty, foggy or similar conditions. The input wiring to a control cabinet is replaced by connecting a sensor to IP67 I/O, thus reducing the wiring effort and saving cabinet space. Pilz is planning to offer a complete IO-Link Safety system for safe communication at field level. As well as the master, the system will include sensors, field devices and compatible accessories, as well as configuration tools. www.pilz.com IO-Link Safety master supports decentralised production ZZZ HXFKQHU FR XN VDOHV#HXFKQHU FR XN 6PDUW 6DIHW\ IRU ,QWUDORJLVWLFV 3URWHFW SHRSOH UHGXFH GRZQWLPH DQG VLPSOLI\ DFFHVV ZLWK 5),' DFFHVV VPDUW LQWHUORFNV VDIHW\ QHWZRUNV OLJKW FXUWDLQV DQG PRUH 6FDODEOH VDIHW\ EXLOW IRU IDVW PRYLQJ HQYLURQPHQWV Pilz’s IO-Link Safety master provides safe communications for functional safety.
