Instrumentation and control laboratory facility upgrade

Daniel Lau

The Instrumentation and Control (IC) laboratory facility uses a Supervisory Control and Data Acquisition system to provide users with the flexibility in designing and implementation of control systems. A new panel is being built and setup due to the growing demand of the IC laboratory facility; the Labview server program must also be expanded to fulfil for this upgrade. Additionally the current Labview server program has several problems within the system and requires some improvement to help student users to use it effectively. The I/O Control board within the new panel provides the necessary connections between the server and the field, as well as controlling the power board. This I/O control board has been configured and will be prepared for the wiring into the patch panel. The patch panel which is connected to both the I/O control board and the power board provides the necessary connections and power to the instruments in the field. The power board is currently being constructed within this project and required a new and clearer wiring diagram to help with the construction of the power board. With the help of the new wiring diagram, the reduction of wiring mistakes and failures provided safety for both the constructor and future users. With the introduction of the new panel, a Profibus network has also been introduced to the IC laboratory facility. The Profibus network provides a demonstration of alternative industrial communication system. Contrast to the established system it has a faster transmission rate, less wiring and intrinsic safety.
