Integrated system design tool

Control system implementation requires many design issues to be addressed and documented. Principal among these are logic diagrams, wiring diagrams, and component layout drawings. Many factors weigh in when selecting among many design documentation approaches. These factors typically include project size, project complexity, probability of replication (will this be done again), support plans (w...

Analyzing, tracking process hazards

Regulatory compliance is driving industry to provide more complete information concerning its manufacturing processes and systems partially because many process industries either use hazardous feedstock or produce hazardous materials. To ensure safe operation of these facilities, OSHA Process Safety Management (PSM) rules (29 CFR 1910.

Pressure Sensing: It’s Everywhere!

KEY WORDS Process control and instrumentation Process sensing Pressure sensing One of the most-used sensors, pressure instrumentation is found nearly everywhere now. The old process standby is still there—chemical change-of-state monitoring still requires tracking such mundane variables as pressure and temperature—but it now can be found, however tiny, in manufactured goods from au...

Ethernet Security, Safety Relies on Common Sense Networking

KEY WORDS Networks and communication Ethernet Internet and intranet PC-based control Device-level networksThe price of freedom? A little less freedom. More users are seeking to gain Ethernet's interoperability and flexibility. However, the relatively greater openness of Ethernet can mean increased network vulnerability, especially when networks are linked via the Internet.

Sensorless AC Drives Fill Price/Performance Niche

KEY WORDSMotors, drives, & motion controlAC variable-speed drivesAC induction motorsAdaptive controlControversial right from their name, "sensorless" ac drives actually use current and voltage sensors to achieve motor control. Even beyond terminology, it's not obvious what sensorless ac drives can or can't do, and where they fit into the big picture.
