With the latest PLC technology, almost anything that can be accomplished next to the machine can be accomplished wherever there is an Internet connection. This White Paper presents new options available for connecting to the PLC from a remote location.

INDUSTRIAL automation is no longer limited by the walls of a production facility. More and more automation is being handled via remote communication, whether it’s from the office or from the comfort of your own home. Today’s PLCs give you the ability to access your control system to handle such tasks as monitoring via a website to determine the condition of a machine or check other statistics.

By applying these simple techniques to modern day control networks, new options are available for the control design. Data collection over great distances is one of the best uses for this technology. Control systems can be more easily integrated within a business network for coupling the supply chain management to the factory floor.
