摘要:
A system, device, and method are disclosed for wirelessly coupling a controlling device to a programmable industrial control equipment such as a programmable logic controller (PLC). The controlling device may, for example, be a personal computer used for programming the PLC. The system includes a radio frequency identification (RFID) unit located at one end of this wireless connection, and also includes at least one antenna at the other end, for communicating with the RFID unit. The RFID unit acts as an intermediary for communication between the programmable industrial control equipment and the controlling device. In case a product in a production line, or a newly added input/output module, provides information that controls a PLC, this control is enhanced by the RFID connection.

A control system includes an Internet web interface to a network of at least one programmable logic control system running an application program for controlling output devices in response to status of input devices. The Web interface runs Web pages from an Ethernet board coupled directly to the PLC back plane and includes an HTTP protocol interpreter, a PLC back plane driver, a TCP/IP stack, and an Ethernet board kernel. The Web interface provides access to the PLC back plane by a user at a remote location through the Internet. The interface translates the industry standard Ethernet, TCP/IP and HTTP protocols used on the Internet into data recognizable to the PLC. Using this interface, the user can retrieve all pertinent data regarding the operation of the programmable logic controller system.

A system, method and apparatus for the automatic configuration of a factory automation device is described. The automatic configuration involves the identification of the device's network address, then involves the search for a configuration server. The configuration server contains the configuration record to download to the automation device, and may contain configuration records for a number of devices. As a result, a search must be made within the configuration server for the configuration record of the specific device. Once found, the configuration is downloaded from the configuration server to the automation device.
摘要:
A method and apparatus for identifying MAC addresses using bar codes is explained. A label that includes the MAC address in bar code format is attached to a network device and used with a bar code reader to enter the MAC address into system network tables.
摘要:
A programmable logic controller is disclosed having a backplane; a local area network interface connected to the backplane, a satellite interface connected to the backplane operatively connectable to a remote computer via a satellite link to receive an automation control program, and an electronic memory for storing the automation control program.
摘要:
A gateway having an input/output scanner is disclosed. The gateway includes a local area network interface, a serial interface, and a processor configured to provide protocol conversion between the local area network interface and the serial interface. Further, an input/output scanner module is operatively connected to the serial interface and configured to poll the slave device.
