Economical EEx i Fieldbus technology
August 2005
Fieldbus & Industrial Networking
Standard parts of the Wago-I/O-System 750 can be used in hazardous areas up to zone 2 and special I/O modules even allow direct wiring into zones 1 and 0.
The number of EEx i modules in this system has increases with the introduction of a 2-channel analog input module which can be used to query data from resistance sensors in zones 1 and 0. It is possible to set parameters which allow the module to be adjusted to the sensor type used such as resistance thermometer sensor, resistance meter or potentiometer.
Another module in the range is a 2-channel digital input module without a diagnostic function that makes it a reasonably priced addition to the 1-channel NAMUR module. Any combination of EEx i modules along with standard modules is possible.

Loop signature Part 2-4: Feedforward Control: Part 3
Michael Brown Control Engineering
Editor's Choice Fieldbus & Industrial Networking
In the previous articles in this series, the basic theory behind feedforward control was discussed, and it was also shown how to apply feedforward in practice. In this article, it will be shown how well feedforward can work in practice by giving a couple of examples.

Loop signature Part 2-2: Feedforward Control: Part 1
Michael Brown Control Engineering
Fieldbus & Industrial Networking
Feedforward control is a powerful technique that can dramatically improve control variance in cases where load changes cause big deviations from setpoint and the actual process dynamics are too slow to allow the feedback controller to operate fast enough to catch these disturbances.
