Advanced network-based data acquisition and control devices. Gateway Interface between the analog, digital and the networked world. Offers an off-the-shelf solution to many distributed test, measurement, and communications applications.
Real-time distributed data acquisition – NetAcquire
Fully programmable NetAcquire AIO server a Networked Voltmeter and also emulates a wide range of virtual instruments.
“Automated Test… simultaneously generating and sampling both digital and analog, to test logic and perform high-speed time and frequency domain measurements.”
Channels: 16 analog in, 2 analog out, 16 digital in, 16 digital out, Speed: 750,000 conversions/second, Analog Resolution: 12-bit analog-to-digital and digital-to-analog converters, with 16-bit resolution optional.
Analog IO – Data Display and Java – NetAcquire
“The NetAcquire Java interface is a package of Java classes that provide communications with one or more NetAcquire nodes. These classes handle all the low-level details of network input/output, flow control, and error handling. ”
JavaBeans components include graphing, disk logging, scaling, and data distribution, Data acquisition and control from local network or Internet, Integrated Web server on NetAcquire server maintains applet security model.
In late 1994, the path of fieldbus took a new, promising direction. Two parallel supplier consortiums-the InterOperable Systems Project (ISP) and WorldFIP North America-merged to form the Fieldbus Foundation.
Fieldbus Foundation – Device Data Networks
‘This advanced digital communication solution was designed from the ground-up to support mission-critical control applications where the proper transfer and handling of data is essential. Foundation technology was created to replace incompatible networks and systems with an open, fully integrated architecture for information integration and distributed, real-time control across the enterprise.”
High Speed Ethernet (HSE) is ideally suited for use as a control backbone. Running at 100 Mbit/s, the technology is designed for device, subsystem and enterprise integration.
Foundation technology is the world’s leading digital protocol for process automation.Industrial network communication system for real-time distributed control. In the Technical Reference area you will find information on Design, installation and operation of Foundation-based plant automation systems….
Foundation Fieldbus H1 uses twisted pair or fiber media to link devices and the controller. Upto 32 Nodes on one port/point.
“Fieldbus is an all digital, two-way multi-drop communications link among intelligent smart field devices and automation systems. FOUNDATION Fieldbus is the Local Area Network (LAN) for instruments used in process automation with built-in capability to distribute the control application across the network.”
Here is a Fieldbus Device – Temperature Head Transmitter
Endress + Hauser – TMT85 – The iTEMP® TMT85 is a head transmitter for assembly in a terminal head DIN form B with 2 sensor inputs for resistance thermometers in 2-wire, 3-wire or 4-wire connection, thermocouples, voltage and resistance transmitters.
