T&D unveils wireless data logging systems
Japanese data-logging provider T&D has unveiled its latest wireless system, combining improved safety and greater convenience. Designed to record and measure data such as temperature and humidity, the new generation RTR500B series includes data loggers and a range of base stations to ensure the safe, wireless collection of recorded data
T
he new system uses T&D’s proven short-range wireless communication for logger to base transmission, and the RTR- 500B series is also compatible with HTTPS – an encrypted
communication feature that ensures superior security. Furthermore, users can register devices and adjust settings not only from a PC, but also a smartphone or via the cloud for greater flexibility and convenience.
The wireless communication range between base and remote units, if unobstructed and direct, is about 150 metres (500ft). However, repeaters can be easily added for an even greater range across a variety of environments. And when used in conjunction with RTR-500BC repeaters, the base unit will automatically select the best route for stable, wireless communication.
By adding the base unit to the free cloud- based T&D WebStorage facility, recorded data can be automatically uploaded, managed and
accessed anytime, anywhere. Automated data collection is carried out using a robust wireless communications protocol.
The devices in the new RTR500B Series are compatible with the earlier RTR-500 series, but also have additional Bluetooth function. This means mobile devices can be used for data logger and base station registration, and to adjust settings.
The base units in the new series comprise: RTR500BW, for transferring data to the cloud or server via a wireless and wired LAN connection, RTR500BC, for downloading data to a PC connected with a USB cable, and also with repeater functionality, and the upcoming RTR500BM (April 2021), for transferring data via 4G mobile connectivity. This impressive new line-up of RTR-505 data loggers meets multifunctional measurement needs including temperature, voltage, 4-20mA and pulse. T&D’s RTR-500 series offers the RTR-574 for monitoring illuminance, UV Intensity, temperature and humidity. The RTR-576 can even
measure CO2 concentration and the RTR-500DC as a wireless portable data collector can be used as line up with RTR-500B series continuously. Finally, recorded data can be effectively managed and analysed using free T&D Graph - high performance software that can also be used in conjunction with the T&D WebStorage cloud service.

Oriental Motor AZ series expands communication options O
riental Motor develop, manufacture and market compact electric motors and drive systems that fulfil the motor needs of products and applications
around the world. They supply a wide variety of reliable, proven technology motors, and are specialists in high quality stepper motors, often used in applications that require positional accuracy.
The Oriental Motor AZ series of closed loop stepper motors has outstanding precision with a high degree of accuracy, which distinguishes them from many of the alternatives currently available. As production processes become increasingly complex, they demand comprehensive communications systems to co-ordinate multiple products. It is essential that at their core are high quality motors capable of delivering reliable, high performance operation. To meet and surpass these needs, Oriental Motor has expanded the communications options for its AZ Series of closed loop stepper motors, with the addition of EtherCAT and Ethernet IP- compatible drivers.
Factories are becoming increasingly intelligent. They have connected systems and factory-wide communications systems,

which create a ‘smart’ environment. Today’s sophisticated production lines incorporate a mix of technologies to achieve the various complex, rapid movements that are executed in the automated processes of numerous industries. Communications protocols are extremely important in today’s sophisticated, high end automation systems. There are many such communications protocols, each with their own strengths and special features, but there are few that are dominant in the field of motor control products. The AZ Series has been acknowledged as a leading closed loop stepper motor with its selection of communications protocols, including CANOpen, Modbus RTU, Mechatrolink 2 and Mechatrolink 3.
A key factor in selection and purchasing decisions is a product’s compatibility with a particular comms protocol. In many cases, having a leading protocol can be a deal maker. There is more to a motor than its design spec. Whilst an excellent motor design specification may win over the mechanical design team, unless it has ‘the right’ protocol (i.e. one that the electrical and comms teams has used and in which the company has invested), it may mean having to forego the first choice for another mechanical option which has the ‘right’ comms protocol.
well-suited to multi-axis machines where several axes interact, requiring true linear interpolation. Oriental Motor EtherCAT-compatible multi-axis drivers have two-axis, three-axis and four-axis driver connection models and are available for connection to the AZ Series DC input stepper motors and electric actuators. The 24/48VDC drivers are compatible with the C1A402 drive profile.
Ethernet IP compatible The AZ Series Ethernet IP-compatible drivers support a battery-free, absolute mechanical sensor motor and driver combination.
To address this, Oriental Motor enhanced their flagship AZ Series closed loop stepper motor range with EtherCAT and Ethernet IP drivers for an even broader selection of communications protocols for the smart, connected factory. The addition of these two protocols extends the communications functionality available with the AZ Series of stepper motors and enables the use of the efficient AZ Series in new and emerging sectors.
EtherCAT compatible
Widely used in automation and particularly valuable in multi-axis systems, particularly
Can be used with all Oriental Motor AZ Series motors as well as with linear and rotary actuators, equipped with the AZ Series.
All AZ Series drivers integrate many protective and monitoring functions, such as temperature, torque, operating speed and current monitoring, protective thermal cutout and emergency stop with electric torque-off functions. Single-phase 100-120VAC and single-phase/three-phase 200-140VAC versions are available. They are for use with all AC input AZ Series motors and actuators.
