Reduces communication costs and ensures reliable monitoring and control

Yokogawa has introduced an enhanced version of the STARDOMnetwork-based control system which reduces communication costs and ensures highly reliable monitoring and control.These enhancements meet a variety of needs in upstream oil and gas development and production, whichYokogawa is targeting based on itsTransformation 2017 mid-term business plan. STARDOM network-based control systems consist of FCN/FCJ autonomous controllers and either a VDS or FAST/TOOLSSCADA server. FCN/FCJ controllers are ideal for the monitoring of oil and gas field installations, pipelines, and other widely distributed facilities that rely on satellites and other types of communications platforms for the transmission of data. In addi- tion to eliminating communications delays and achieving high quality communications, the companies that operate such facilities are seeking to reduce communications costs by limiting the volume of data that needs to be transmitted. Product features: • Unsolicited response support • Expanded support of standards for gas well applications • Strengthened security measures Enquiries:Tel. 011 831 6300 or email Christie.cronje@za.yokogawa.com

Miniature photoelectric sensors – high performance ifm electronic ’s new diffuse reflection sensors provide reliable background suppression, even in the case of highly reflective backgrounds such as moving machine parts. The clearly

defined consistent light spot ensures precise object detection. There is no scattered light which could interfere with other photoelectric sensors in close vicinity. For connection the user can choose between a potted cable, M12 pigtail or a M8 metal connector on the housing. The O6 range features a potentiometer for in-

tuitive setting, and the light-on or dark-on mode is selected via a rotary switch. The diffuse reflection, through-beam and retro-reflective sensors are distinguished by a good price/per- formance ratio. An extensive range of accessories is available making the sensors ideal for universal applications. Enquiries:Tel. 012 450 0370 or email info.za@ifm.com
