WikipepiA 10-Link 10-Link is a short distance, bi-directional, digital, point-to-point, wired (or wireless) industrial communications networking standard. (IEC 61131-9) used for connecting digital sensors and actuators to either a type of industrial fieldbus or a type of industrial Ethernet. Its objective is to provide a technological platform that enables the development and use of sensors and actuators that can produce and ‘consume enriched sets of data that in turn can be used for economically optimizing industrial automated processes and operations, The technology standard is managed by the industry association Profibus and Profinet International. i System overview An TO-Link system consists of an IO-Link master and one or more IO-Link devices, ie. Sensors or Actuators. The 10-Link master provides the interface to the higher-level controller (PLC) and controls the communication with the connected [O-Link devices, ‘An 1O-Link master can have one or more 1O-Link ports to which only one device can be connected at a time. This can also be a "hub" ‘which, as a concentrator, enables the connection of classic switehing sensors and actuators. ‘An 1O-Link device can be an intelligent sensor, actuator, hub or, due to bidirectional communication, also a mechatronic component, ‘eg. a gripper or a power supply unit with I0-Link connection. Intelligent with regard to TO-Link means that a deviee has identification, data e.g. a type designation and a serial number or parameter data (e.g, sensitivities, switching delays or characteristic curves) that can be read or written via the I0-Link protocol. This allows parameters to be changed by the PLC during operation, for example. Intelligent also means, however, that it ean provide detailed diagnostic information, 10-Link and the data transmitted with it are often used for preventive maintenance and servicing, e.g. its possible to set an optical sensor in such a way that it reports via 1O-Link in good time if it threatens to become dirty. Cleaning no longer comes as a surprise and blocks production; it ean now be put on a production break. ‘The parameters of the sensors and actuators are deviee- and technology-specifie, which is why parameter information in the form of an IODD (10 Device Description) with the description language XML. The IO-Link community provides interfaces to an "IODD Finder" 21 ‘which can be used by engineering or master tools to present the appropriate TODD for a deviee. Connector Cabling is in the form of an unshielded, three or five conductor cables, not longer than twenty meters, and a standardized four or five ppin connector. The master and device pin assignment is based on the specifications in IEC 60947-5-2.0] For a master, two port classes are defined, port class A and port class B. Port class A uses M5, M8, or Miz connectors, with a maximum of four pins. Port class B uses tan mips ink teonly Miz connectors with § pins. M2 connectors are mechanically assigned to the master and male connectors to the device. -coded according to IEC 61076-2-101.!4] Female connectors are {At the master pin 1 to pin 3 provides 24V DC power with max. 200 ma for an optional power supply of the 1O-Link device. Pin 4 is used ‘8s a digital input (DD) or digital output (DO) according to the IEC 61131-2 specification to allow backward compatibility to proximity sensors according to TEC60947-5-2 oF other sensors or electrical switches ‘The 10-Link master sends a wake-up current pulse to get the 1O-Link device from the serial input-output (SIO) state into the single- drop digital communication interface (SDCI) state. In the SDCT state the 1O-Link master exchanges information frames with the 10- Link device, 1m a port class A the pins 2 and 5 are not specified and are left to the manufacturer to define. In a port class B the pins 2 and 5 are configured as an additional power supply. Protocol ‘The 10-Link communications protocol consists of communication ports, communication modes, data types, and transmission speeds. The ports are physically located on the master, and provide it a means for connecting with terminal devices and for bridging to a fieldbus or Ethernet, There are four communication modes that can be applied to a port connected to a terminal device: 10-Link, DI, DQ, and Deactivated. 10-Link mode configures the port for bi-directional communications, DI mode configures it as an input, DQ configures it as an output, and Deactivated just simply deactivates the port. There are four data types: process data, value status data, device data, and event data, The protocol ean be configured to operate at transmission speeds of either 4,8 kilobaud, 38.4 kilobaud, of 230.4 kilobaud. The minimum transmission time at 230.4 kilabaud is 400 microseconds. An engineering tool is used for configuring, the master to operate as the network bridge.!71 10-Link Wireless 10-Link Wireless! is an extension of 10-Link on the physical level. An TO-Link Wireless Master ("W-Master") behaves like a Master to the superordinate system. There are only virtual ports "down to the 1O-Link Wireless Deviees ("W-Deviees") A transmission eycle consists of two phases. To transmit output data, the W master sends a Multicast-W frame (Downlink) with data for the W devices in assigned time slots, Then the W-Master goes on reception and eollects in the Uplink Data from the W-Devices which transmit one after the other according to an agreed fixed scheme. tan micpdinrpviti ink aeTo secure the transmission Frequency Hopping and Channel-Blacklisting are used. 10-Link Safety 10-Link Safety is an extension of 10-Link by providing an additional safety communication layer on the existing master and device layers, which thus become the "FS master” and "FS device". One also speaks of the Black Channel principle. The concept has been tested by TOV SUD. 10-Link Safety has also extended the OSSD (Output Switching Signal Device) output switching elements commonly used for functional safety in a non-contact protective device like a light curtain to OSSDe. As with standard IO-Link, an FS-Device ean be operated both in ‘switching mode as OSSDe and via functionally safe IO-Link communication During implementation, the safety rules of IEC 61508 and/or ISO 13849 must be observed.
