    Ethernet to the Field Future solution for process automation and instrumentation in remote and hazardous locations A cooperation between: Developments are underway to realize an Advanced Physical Layer (APL) for Ethernet that can be used in process automation and instrumentation to connect field devices in remote and hazardous locations. Ethernet to the Field is a vision driven by new technological developments, such as the Industrial Internet of Things and the German Industrie 4.0 initia- tive. Both have introduced new paradigms to enable applications based on FUNCTIONS AND digital real-time representations of virtually any object.

    MOVE TO IP WITH CONFIDENCE Eliminating Infrastructure Barriers to IP Camera Adoption The Phybridge CLEER & EC Switches Fast Ethernet & PoE over Coax with Five Times the Reach of Traditional Switches Analog to IP Cameras Made Cost Effective, Simple, and Robust Move to IP Cameras With Confidence Camera intelligence, multi point communications, video compression and HD quality are some of the reasons organizations want to upgrade to IP cameras and IP video surveillance. One of the biggest barriers is building an IP platform that can mirror the robustness of the existing coax point-to-point infrastructure. Latency sensitive video streaming combined with long reach requirements impose additional layers of complexity and costs. Best practices dictates that a separate network should be established for IP Cameras. The Phybridge CLEER (Coax Leveraged Ethernet Extended Reach) & EC (Ethernet over Coax) switches not only eliminate infrastructure barriers and challenges, they also deliver the ideal robust platform that is cost effective, simple to deploy and simple to manage.
