  • Bridges and Gateways and Switches, Oh My!
    as Ethernet-based utilities, they can also apply to other, non-ethernet applications as well, such as USB or Serial. While the terms bridges, gateways and switches are often used interchangeably, they each describe devices with distinct functions.
  • One Gateway That Can Do It All (.pdf)
    The term "Fieldbus" refers to a collection of communication protocols that were introduced to replace 4 to 20 mA analog signals. Fieldbus protocols include DF1, PROFIBUS, and Modbus for serial, and EtherNet/IP, PROFINET, and Modbus TCP for Ethernet. In this paper we concentrate on DF1 and EtherNet
  • Prevent Power Surges with Full Spectrum Surge Protection
    are essential components of many modern automation systems; however, they are also particularly susceptible to power surges from voltage and current spikes. In these systems, serial device servers are key communication gateways that connect the broader Ethernet network with specific serial devices
