What is multi-protocol？
Multiprotocol is an architecture that can run multiple protocols.
In many industrial applications, the traditional serial "fieldbus" has been replaced by high-bandwidth Ethernet that can be linked to corporate networks. Although there are several protocols for industrial Ethernet, such as PROFINET, Ethernet / IP, EtherCAT, ModbusTCP, and others, they are not compatible with each other. Therefore, when designing products for industrial Ethernet, compatibility with various protocols must be considered.
One solution is multi-protocol Ethernet switching products.
Efforts for Next-Generation Ethernet Standard IEEE 802.1 TSN (Time Sensitive Network)
The standard Internet has advantages in terms of openness, compatibility and cost, but there are problems such as the inability to fix latency and the lack of guaranteed bandwidth. While industrial Ethernet addresses these challenges, proprietary hardware protocols have hampered its adoption.
For this reason, the IEEE 802.1 Time Sensitive Network (TSN) uses standard Ethernet hardware that has been widely used and is being studied to meet the needs of all industries with a unified standard.
In TSN, IEEE is the group leader and AVNU is promoting the creation of the ecosystem, and the ADI evaluation board is used as the test head.
Analog Devices’ Ethernet switch fido5100/5200
Analog Devices (ADI) fido 5100 is an Ethernet switch that supports PROFINET, EtherNet / IP, Modbus / TCP, POWERLINK, and SERCOS III. fido5200 also supports EtherCAT.
The fido 51/00/5200 supports each protocol by downloading the firmware from the host processor at power up.
