CANopen-certified by mid of March 2023

From June 2022 to March 2023, six device (series) and one component have passed the CANopen conformance test performed by CAN in Automation (CiA).

The CANopen test certificate issued by CiA ensures the device’s conformance with the CANopen application layer and communication profile (CiA 301). This helps manufacturers to prove CANopen compliance of their products to the customers.

Baumer Electric (Germany) has received the CANopen approval for its EAMxxx MT series. For example, the EAM300 absolute multi-turn encoder features a 30-mm diameter and 53,3-mm length. The encoder series features a 14-bit single-turn resolution (16384 steps per revolution) and an 18-bit multi-turn resolution (262144 revolutions). It also features a position precision up to ±0,15°. The IP67-rated product is available in combinations of full or hollow shaft encoder with plug or cable connection as well as axial or radial outgoing unit. Operating temperature ranges from -40 °C to +85 °C. Implemented CANopen, profiles include CiA 406 encoder device profile and CiA 417 CANopen Lift application profile. The devices also support the CiA 305 LSS (layer setting services) specification allowing configuration of node-ID and bit rate via the CAN interface. The company recommends usage of the CiA 406 variant, for example, in medical technology such as mammography, radiology, and X-ray devices, or in accessory equipment in agricultural technology and construction machinery, as well as in factory automation with limited installation space. The CiA 417 versions are dedicated for elevators.

CG Drives & Automation (Sweden) certified the CANopen interface of the Emotron TSA softstarter series available for 5,5-kW to 1000-kW (16 A to 960 A and 200 V to 690 V) applications. The softstarters incorporate 3-phase control together with sophisticated algorithms for torque control. The devices have the ability to handle several different starting and stopping modes, braking ability for fast stopping, a reverse current brake, and slow speed/jog mode. Such functions as thermal motor protection, smart load monitoring, thermistor input, and bypass contactor are implemented. The softstarters are dedicated for applications where a variable speed is not required i.e. for pumps, saws, conveyors, mixers, and centrifuges. Using interface modules, communication options are given for connection to CANopen, DeviceNet, Ethernet, and further networks. Variable I/Os and a PC-tool for commissioning and parameter monitoring complete the product offer. The softstarter family is built for challenging environments with coated boards to withstand tough conditions. Built-in programming blocks, such as logical functions, comparators, SR flip-flops, counters, and timers enable customization of the devices. A real-time clock is used for time registration in the event log and to enable pre-programmed start and stop. No additional equipment is required for installation in an application. A multi-lingual control panel with single-function keys and copy function enable global application of the devices.

The certified Cifx M223090AE-CO\F by Hilscher (Germany) is a PC card M.2 2230 key A+E, which offers PCI Express interface technology in a compact format (22 mm x 30 mm). The card enables CANopen communication for PC-based automation. Classic application examples are industrial PCs for plant or local machine control, HMI (human machine interface) panels for machine monitoring and operation, as well as specific solutions such as optical inspection systems, test benches, simulation systems, and robotic solutions. The card can be configured as a CANopen NMT (network management) server according to the CiA 301 specification. The entire protocol stack is processed on company’s proprietary Netx 90 chip. Like all Cifx PC cards, the M.2 version has a uniform user interface for all formats and protocols. They use the same drivers, configuration tools, and a standardized API (application programming interface). A variety of drivers simplifies integration of the card in an application. Data is accessed via a dual-port memory. The card includes a detached network interface (15 cm), which is optionally available with an M12 connector. Operation without a heat sink in the temperature range of up to +70 °C is foreseen.

Sick (Germany) has certified the updated version of its MLS (magnetic line sensor). The sensor is used for navigation of automated guided vehicles and carts (AGVs/AGCs) applicated in production logistics, materials management, material storage, etc. Navigation is done by aligning the sensor to the center of the magnetic lane. Sensor positions are transmitted to the vehicle control via the tested CANopen interface. The sensor differentiates between up to three lanes. Thus, the vehicle can maneuver through branches and lane junctions. The device is available for detection ranges from 100 mm up to 1 m. An integrated inertial measurement unit (IMU) supports vehicle navigation with information on the position of the sensor.

Schneider Toshiba Inverter (Japan) has received a CANopen certificate for its ATS48x CANopen soft starter series dedicated for industrial applications. For instance, the Altivar ATS480 for operating currents up to 1700 A is available from Allied Electronics & Automation. Connectivity for CANopen and Devicenet is given. Soft starters enable a gentle ramp-up to full-speed motor operation. ATS480 series are torque-controlled and equipped with torque ramp, dynamic braking, and DC injection stop modes. They are rated for operating voltages from 208 V to 690 V, operating currents from 17 A to 1700 A, and effective powers from 4 kw to 900 kW. Suitable applications extend from economical and high-horsepower motors (>500 HP), pumps, fans, compressors, saws, pulpers, agitators, mixers, grinders, crushers, refiners, presses, and material handling equipment. Schneider's Ecostruxure platform helps users simplify architecture selection, design, and execution processes. Digital features include remote commissioning and embedded QR codes that reveal parameters for on-site troubleshooting. A text-keypad is capable of displaying warnings and history. In terms of cybersecurity, the devices feature secure boot and firmware upgrades. Threat intelligence capabilities can generate security reports and restrict or disable ports and services, as well as user account authorization.

Temposonics (former MTS Sensors, USA) has successfully tested its E-Series transducers. The series includes EP, EL, and EH position sensors with stroke lengths from 50 mm to 2540 mm. The device implements the CANopen NMT (network management) server (CiA 301) and layer setting services (LSS, CiA 305) to configure sensor’s node-ID and bit rate. It also supports the CiA 406 (version 3.1) device profile for encoders performing functionality of Class 2 and implementing the CAM functionality. The device works on bit rates of up to 1 Mbit/s. For measurements, a time-of-flight based magneto-strictive position sensing principle is used. The IP67 or IP69K rated sensor housing (rod/profile) protects the sensor element. The sensor electronics housing, which is a rugged aluminum/stainless steel construction, contains the complete electronic interface with active signal conditioning. The sensor can be connected directly to a control system via a 5-pin M12 plug connector. The device is dedicated for operation at temperatures from -40 °C to +75 °C and operating voltage of 24 V_DC.

The MH-4-CAN OEM (original equipment manufacturer) pressure sensor from Wika (Germany) supports CANopen and J1939 interfaces and is dedicated for use in mobile working machines. It enables working and control pressure measurement in construction equipment, agricultural and forestry machines, mobile cranes and MEWPs (mobile elevating work platforms) as well as material handling equipment and municipal vehicles. The sensor measures at temperatures between -40 °C and +100 °C. With its up to three times overpressure limit, it withstands hydraulic pressure spikes and is optionally available with a restrictor. Due to metallic shielding, it works interference-free at field strengths of up to 60 V/m. In addition, vibrations up to 40 g and shocks up to 100 g have no influence on the measurement quality. The maintenance-free sensor is reliable and safe in operation over the entire life cycle, says the manufacturer. Even after more than 100 million load cycles, the long-term drift is still less than 0,1 % FS (full scale), continues Wika. Customization and brand labelling of the MH-4-CAN is possible.
