Combining an access point and gateway, Yokogawa Electric Corporationsays its new ISA100 Wireless module is ideal for linking multiple wireless devices with a host controller.

The manufacturer says the compact device – it is 90mm long and has a diameter of 23mm – can be installed in locations that are inaccessible to wired devices, and can be set up by users with no previous experience.

Yokogawa says the ISA100 Wireless can function as both an AP and gateway because it incorporates an FN110 field wireless communication module with a built-in gateway.

It adds that when used with an LN90 that incorporates a power supply adaptor and a hostsystem communications interface, the new module can link up to 20 field wireless devices with a host controller or other device via the RS-485 Modbus general-purpose communications protocol.

ISA100 Wireless is the protocol for wireless systems for industrial automation including process control and related applications.

Yokogawa claims it introduced the world’s first device to comply with the protocol in July 2010. Since then, the firm says it has added products to its range that can measure flow rates, temperature, pressure and vibration, as well as gateways and adaptors that enable conventional field devices to communicate wirelessly.
