Automated factories often have computer numerically controlled (CNC) machines in the production line. These machines are connected on a single Ethernet-based network so that central planning and control is possible. Most of these machines use a RS-232 serial communication interfaces. Dedicating a special ruggedized PC at each workstation is not only expensive, but it also means that an operator must go to that particular workstation to implement changes or troubleshoot problems. Using a Quatech ThinQ Serial Device Server, each CNC machine can be connected to the factory's Network and each CNC can be remotely monitored and controlled. This means a single technician in a single location can oversee and service an entire factory, or an entire factory complex. And, she can do it using a standard web browser, from anywhere on the planet, so long as she has access to an Internet-enabled computer. (Note that such a system can also be implemented on a private network or Intranet, and that Quatech's ThinQ product line provides security parameters that can be set to prevent unauthorized access to your systems.)
