IO-Link is a standardized communication technology for data exchange with sensors and actuators, enabling continuous communication from control systems to sensors. It offers benefits like cost reduction, innovative machine concepts, and improved maintenance through self-diagnosis and data analysis.
IO-Link systems consist of a master, device, and unshielded cables. The technology supports various operating modes, including data transfer and digital input/output, with specific connection assignments defined by standards.
When an IO-Link device is connected to a master, communication begins with a wake-up pulse from the master. The master then determines the device's data transmission rate, which can be one of three specified rates: COM 1 (4.8 kBd), COM 2 (38.4 kBd), or COM 3 (230.4 kBd). The master supports all rates and adjusts automatically.
The response time is influenced by the device's minimum cycle time and the master's processing speed. IO-Link communication is robust against interference, using a 24 V level for transmission. Errors are retried up to three times before the connection is terminated and reported as an error.
Four data types are used: Process data and value status (cyclic), and device data and events (acyclic). Process data lengths range from 0 to 32 bytes, and value status indicates data validity. Device data includes parameters and diagnostics, while events report errors and warnings.
Device profiles standardize access to devices, ensuring uniformity across different devices. The IODD file, provided by manufacturers, contains communication properties, parameters, and other essential data, ensuring universal handling.
Configuration software is required for setting up an IO-Link system, allowing device assignment and address allocation. The software uses IODD files for communication and parameterization.

Flow Sensors Technique and application Function The function of the flow controller is based on the thermodynamic principle. The sensor is heated internally a few degrees °C compared to the medium into which it projects. When the medium flows, the heat generated in the sensor is conducted away by the medium, i. e. the sensor cools down. The temperature within the sensor is measured and compared to the temperature of the medium. The state of flow can be derived for each medium by the temperature difference attained. – In metal processing, e.g. rolling mills and wire drawing machines, the rolls...

Dimensions of the gasket Thread 3 = Chamber 4 = Edge 5 = Counterpart The temperature-sensitive measuring elements are fitted in the tip of the probe. The probe tip and the adjoining thread/mounting part are made in one piece of stainless steel in many probes. This guarantees absolute tightness and high compressive strength. Special materials are used in corrosive, and particularly in oxidizing media, since stainless steel shows only limited resistance to corrosion in this application. In standard applications, probes can be mounted independently of the direction of flow of the medium. In any...

Flow Sensors Technique and application NPT threads NPT threads can be provided as an alternative for all types which have a G1/2 or a G3/4 thread. NPT threads are conical and must be screwed into an equally conical counter-part. Two types of NPT threads must be distinguished. NPT thread according to ANSI B 1.20.1 does not ensure a good seal by itself and requires the use of a sealing medium, e.g. Teflon tape. It is not possible to use flat gaskets with this type of thread. Inline sensors are inserted directly into the line of a pipe. This design does not feature any measuring pins protruding...

Flow Sensors Technique and application Amplifiers All amplifiers have a multicolour LED display which visually indicates the flow tendency. If the LED light is red, the preinstalled limit value is not reached and the switching output is not activated. The yellow LED indicates that the limit value was reached and the output is active. In addition to the yellow LED, 4 more green LEDs can light up to indicate how much the limit value is exceeded. For the installation of the amplifiers, make sure that the devices are not subject to heat build-up. The distance between adjacent devices should not be...

Flow Sensors Technique and application • Terminology Detection range The detection range of a probe or compact device indicates the flow velocities of the medium for which the probe can provide an analysable signal. If the medium is not specified, the details for water are applied. Because the different media have different thermal conductivity, the detection range as well as the temperature drift are also dependent of the respective medium. At the upper and lower limit of the detection range, the temperature drift is higher. The detection range does not limit the maximum flow rate a sensor may...

Switching output General • The output is active when the yellow LED is lit. • Set the switching point with the potentiometer at the front of the device. • Keep the flow rate and medium temperature stable during adjustment and wait for the temperature to equalise between the sensor and the medium. • The flow rate must be within the detection rate of the measuring probe. • If present, remove the protective screw M3 x 4 from the potentiometer opening for the duration of configuration. Monitoring a flow limit for being exceeded • Specify the flow rate or stop the flow and wait for the standby time. •...
