What is Multiprotocol?

Multiprotocol is an architecture that can run multiple protocols.

In many industrial applications, traditional serial "fieldbuses" are being replaced by Ethernet, which provides higher bandwidth and links to corporate networks. Industrial Ethernet includes PROFINET, Ethernet/IP, EtherCAT, ModbusTCP, and several other protocols, but they are not compatible. Therefore, when designing products for Industrial Ethernet, compatibility with various protocols must be considered.

One way to solve this problem is to create an Ethernet switch product that supports multiple protocols.

Initiatives for the next generation Ethernet standard IEEE 802.1 TSN (Time Sensitive Network)

Standard Internet has advantages in terms of openness, compatibility, and cost, but it also has issues such as the inability to fix latency and the inability to guarantee bandwidth. Industrial Ethernet addresses these challenges, but proprietary hardware protocols are hindering its adoption.

Therefore, the IEEE802.1 TSN (Time Sensitive Network) is being considered to meet the requirements of all industries as a unified standard using standard Ethernet hardware that has been widely used. Masu.
For TSN, IEEE is the group leader and AVNU is promoting the creation of the ecosystem, and ADI's evaluation board is used as the test head.

Analog Devices Ethernet switch fido5100/5200

The fido5100 from Analog Devices (ADI) is an Ethernet switch that supports PROFINET, EtherNet/IP, Modbus/TCP, POWERLINK, and SERCOS III. In addition to these, fido5200 also supports EtherCAT.

fido5100/5200 supports each protocol by downloading firmware from the host processor when powered on.
