  • Publication number: 20250103527
    Abstract: The present disclosure relates to an I/O station, connected with a plurality of network devices in an automation system. The station comprises a plurality of I/O modules, each I/O module providing one or more I/O channels connecting respective one or more field device(s). The station also comprises an I/O network interface for forwarding data between the modules and the network devices via a network. Each of the channels connecting a respective field device is communicatively connected to at least one of the network devices via the network. The station further comprises a non-volatile storage storing configuration data for the station.

  • Patent number: 6937844
    Abstract: The present invention relates to a arrangement and method for providing wireless communication between GPIB devices and a host computer. An GPIB adapter (100) according to the present invention provides wireless communication between a GPIB device (200) and a computer (120), the adapter comprises a command handle (140)r adapted for communication with a wireless communication module (130). The adapter further comprises a GPIB control unit (150) and the command handler is adapted for executing GPIB function calls directed to a GPIB device through the GPIB control unit (150). The command handler comprises a GPIB driver (344) which is adapted for communication with the GPIB control unit (150). The arrangement makes it possible for the adapter to provide complete GPIB functionality.
