PID Modifications for Unreliable Communications

As noted in my December 4th posting, the Hart Communication Foundation has adopted the IEEE 802.15.4 physical layer for wireless HART. One of the technical challenges is that the 2.4 GHz spectrum defined by IEEE 802.15.4 is also used by Wi-Fi and Bluetooth devices. Also, some electrical devices found in industry generate noise in this …

Control Using Wireless Transmitters

Over the last few years the process industry has expressed a growing interest in the application of wireless technology for field measurements. The ISA-SP100 Committee was established in early 2005 to set standards and recommended practices for implementing wireless systems in the automation and control environment with a focus on the field level. Also, various …
