Continued market growth is testament to the development of PLCs

摘要

The PLC versus IPC or PC based control debate has been with us for over two decades now, with commentators making various predictions about the rise of industrial controllers with PC based internals versus purely PLC solutions. Yet according the latest figures from Gambica, the PLC market continues to grow. Mitsubishi Electric PLC product manager, Hugh Tasker offers some thoughts on why Mitsubishi Electric is heavily invested in PLC technology with a massive installed base and a continuous stream of innovations being released to the market. Indeed, it is interesting as part of the PLC versus IPC debate to note that there has been some blurring of the technologies, with each now incorporating some of the features of the other. From the PLC perspective, this includes everything from the inclusion of embedded web servers to the availability of plug-in PC modules such as Mitsubishi Electric's C-Controller.
