PLC and SCADA Control Systems

Back


Various applications are available such as Multiple Generator Control, Multiple Utility control (including Peak Lopping/Shaving), Load Management control and Balance of Plant control. At a basic level, a Master PLC panel is wired in conjunction with the generator control panels and associated switchgear in the system to provide the control for the power network and the starting and stopping of the generators. For more complex systems, a communication network can be utilised to facilitate the transfer of data between the PLC and outstations from different locations. The network comprises physical connections between all intelligent devices (or nodes) arranged into a ring formation and operating on the EtherNet/IP protocol.

Overview

Caterpillar offers a complete solution for the monitoring and control of generators and associated switchgear in applications where complex control philosophies are employed. Various applications are available such as Multiple Generator Control, Multiple Utility control (including Peak Lopping/Shaving), Load Management control and Balance of Plant control. At a basic level, a Master PLC panel is wired in conjunction with the generator control panels and associated switchgear in the system to provide the control for the power network and the starting and stopping of the generators.
