Industrial Ethernet Embedded Switches

Advantages of designing with ADI Industrial Ethernet Embedded Switches

These Industrial Ethernet embedded switches are designed so you can choose the type of processor that fits your application and not be forced to use a particular vendor’s protocol stack. REM attaches to the memory bus of a processor and looks like any other peripheral out on that bus. The memory cycle for REM goes down to 32 ns (125 Mbps with a 32-bit bus) to support the 12.5 µs cycle time for EtherCAT and the 31.25 μs cycle time for PROFINET IRT. Data is transferred to and from the switches using PriorityChannel queues, so real-time data transfers can interrupt nonreal-time data transfers without delay. These queues are managed by a switch driver and interface to the protocol stack to achieve the most efficient data transfers possible. This also means that application software doesn’t have to worry about managing the switch, setting low level registers, or keeping track of intricate time management processes.

Another performance advantage of the Industrial Ethernet embedded switches is that their PriorityChannel technology make them immune to network loading effects. This advantage ensures that your application is up and running all the time, every time. The REM switches intelligently filter packets to keep unwanted traffic from your processor, manage low priority traffic based on the loading of your processor, and guarantee the timely delivery of high priority packets, regardless of overall packet load.
