The ODVA EtherNet/IP network standard is gaining popularity as an industrial protocol, and wireless ethernet technologies have emerged that can now reliably reduce network costs while improving plant production.
This article explores the challenges of developing telemetric SCADA systems and covers the seven most important features to look for in selecting a GPRS solution.
While EtherNet/IP has many advantages, cable installation is often expensive, and communications to remote sites or moving platforms may not be reliable or cost effective. Wireless ethernet technologies have emerged that can now reliably reduce network costs while improving plant production.
Trio Datacom has released a 512 Kbps version of the JR900 frequency hopping data radio for industrial ethernet communications in the 900 MHz licence-free band. The JR900 has data rates at twice the speed of the original to enable a wide variety of applications that require higher data capability than typical SCADA and telemetry systems can provide.
The Wireless Point I/O Adapter (ILX34-AENWG) is a high-speed, standards-based 802.11g wireless I/O communication adapter offering a wireless alternative for linking Rockwell Automation controllers to distributed process I/O modules.
The ISA Standards & Practices Board (S&P) has voted to approve the ISA-100.11a wireless standard, making it an official ISA Standard.
When it comes to controlling water and wastewater supply, the Tweed Shire have a lot to cover. Their water supply system comprises 24 water pumping stations, eight treatment plants, 174 wastewater pumping stations and 641 km of water-mains piping.
Lantronix has upgraded its existing compact XPort serial to ethernet device server with RS485 protocolÂ interface feature. The standard XPort is now able to be used inÂ RS485/RS422/RS232 interface applications,Â and the XPort-Modbus will be suitable for industrial Modbus use.
TRIO Datacom have introduced the JS100 Ethernet to Serial converter designed to allow communications over point to point and point to multipoint radio channels with remote devices, eg, RTU or PLC, which have ethernet data ports.
The NI wireless sensor networks (WSN) platform offers a complete remote monitoring solution that consists of NI LabVIEW graphical programming software and reliable, low-power wireless measurement nodes.
Designed for robust, secure communication, the K-Tek DX80 wireless transmitter and receiver includes two devices: a node that resides in the field and interfaces to K-Tek's measurement devices; and a gateway that resides in the main control panel and interfaces to a PC or PLC.
