GENERAL DESCRIPTION

The fido5100 and fido5200 are real-time Ethernet, multiprotocol

(REM), two-port switches. The REM switches provide customers

the flexibility to select processors that best fit the application. The

switches offer 10 Mbps/100 Mbps throughput and support most

Layer 2 or Layer 3 protocols.

The fido5100 supports PROFINET real-time (RT) and isochronous

real-time (IRT), EtherNet/IP with and without device level ring

(DLR), Modbus TCP, and POWERLINK. The fido5200 supports

EtherCAT and all protocols defined for the fido5100. The switches

contain software drivers for each protocol. The software drivers

provide an API for integration with any field device or protocol

stack.

The REM switch architecture incorporates Analog Devices, Inc.

PriorityChannel™ technology for efficient data transfers. Data is

transferred to and from the switch using PriorityChannel queues.

Thus, real-time data transfers can interrupt non-real-time data

transfers to ensure timely delivery of critical data. These queues

are managed by the switch driver and interface to the protocol

stack to achieve the most efficient data transfers without application

software involvement.

Additionally, PriorityChannel technology allows the switches to be

immune to network loading effects. The REM switches automatical-

ly filter packets to prevent unwanted traffic from the processor,

manage low priority traffic based on processor loading, and guaran-

tee the timely delivery of high priority packets regardless of overall

packet load.

The software drivers include a standard set of interfaces to sup-

port standard, low priority, TCP/IP communications, basic switch

initialization, timer configuration, and interrupt management. This

interface is common to all REM switch drivers, easing the porting

of the application to each supported protocol. Each protocol has its

own interface that configures the REM switch for optimal operation.

This configuration is transparent to the user and can be performed

at any time, including a soft-boot to change protocols without

resetting the host processor or PHYs.
