Azbil Corporation announced the release of the Smart HART Modem model AZ-1SHM, which facilitates the configuration and adjustment of HART communication–compliant field devices at plants and other manufacturing sites. Launched in Japan, China, Southeast Asia, Germany, United States, and other locations in October, the 1SHM will be available in South Korea in mid-November.
A HART modem is a digital communication interface device for setting up and configuring HART communication–compliant field devices, such as sensors and valves, which are installed in large numbers at manufacturing sites. In a new or expanded plant or during shutdown maintenance, maintenance personnel connect a host device via HART modems to HART devices to configure various parameters. In some cases, a problem related to wiring, connection environment, device compatibility or the power supply may prevent a connection. To investigate and mitigate the problem, a power supply, oscilloscope, or other equipment may be required. Additionally, field devices are sometimes installed in hard-to-reach places, putting the worker in danger.
The new 1SHM solves these problems. In addition to communication interface functions, it is equipped with functions to identify the cause of communication problems during configuration and setup. It also has wireless connectivity and a power supply function, allowing more efficient and safer maintenance. Since the modem can be used with Azbil’s and other companies’ HART devices, maintenance workers can safely and quickly handle communication problems using a single 1SHM unit.
Features included are:
- LEDs for quick understanding of device status
The front LEDs enable users to instantly see the power and communication status. Elementary mistakes that cause connection problems (no power supply, incompatibility, etc.) can be detected quickly.
- Communication problem diagnosis
A single 1SHM unit and included software provide functions that usually require dedicated equipment (oscilloscopes, protocol monitors, etc.), including displaying communication waveforms, noise level, and communication data. Workers can identify causes of communication problems quickly and reduce downtime.
- Power for field devices
The 1SHM can power a HART device, ensuring reliable setup and configuration.
- Wireless connection to host
Field devices are sometimes hard to reach. Also, the work environment may worsen due to weather conditions, and maintenance work in a safer and more comfortable place may be desired. The 1SHM can connect to the host device wirelessly via Bluetooth Classic, so the user can work in a safe place comfortably without being restricted by cable length.
- Easy-to-understand and highly visible design with ergonomics in mind
The ergonomic design offers high usability and visibility.
