Analog Devices Inc. Fido5100/Fido5200 REM Switches

Analog Devices Fido5100/Fido5200 Real-Time Ethernet Multiprotocol (REM) Switches are designed as programmable IEEE 802.3 10Mbps/100Mbps Ethernet Internet Protocol Version 6 (IPv6) and Internet Protocol Version 4 (IPv4) switches that support virtually any Layer 2 or Layer 3 protocol.

Analog Devices Fido5100 REM Switch supports the following protocols:

• PROFINET real-time (RT) and isochronous real-time (IRT)
• EtherNet/IP with and without device level ring (DLR)
• Modbus TCP

The fido5200 REM Switch supports the following protocols:

• EtherCAT
• All protocols defined for fido5100

The fido5100/fido5200 switches are personalized to support the protocol used by the firmware downloaded from a host processor. These 2-port, embedded Ethernet switches can interface to any processor, including any Arm® CPU and the fido1100 Communication Controller. The host processor can implement any protocol stack by integrating it with the REM switch driver. To support fast startup and quick-connect type network functionality, the firmware is downloaded in power-up mode and contained in the REM switch driver. The fido5100/fido5200 REM Switches can be ready for network data operation in less than 4ms. These 2-port Ethernet switches also have a powerful memory bus interface that supports both 16- and 32-bit wide busses and achieve data transfer rates up to 167 Mbytes/sec.
