Product Details

The fido2100 is part of the Innovasic fido® family of real-time communication products. The fido2100 is a managed, 3-port Ethernet switch with support for IEEE-1588 and Device Level Ring (DLR) protocol. The fido2100 enhances the capabilities of Innovasic’s line of Industrial Ethernet products by providing an infrastructure element with low latency, time synchronization and redundancy for any embedded Industrial Ethernet solution.

The fido2100 is an IEEE 802.3 standard compliant, Layer 2 switch that is compatible with the IEEE 802.1D standard. It has three ports: two are external ports that function as physical ports of a product and one is an internal port that connects to the host CPU. Each of the three ports has an IEEE 802.3 compliant MAC and the ports are interconnected with each other through full wire speed, non-blocking switching logic. Figure 1 illustrates the top-level blocks of the fido2100 architecture.

The pass-through of traffic is handled swiftly by using cut through forwarding to pass traffic to the other external port. This is accomplished without host CPU intervention, which keeps throughput time host interaction to a minimum and keeps pass through delay to a minimum.

The fido2100 also has the ability to operate in a DLR configuration, which provides media redundancy amongst its members. Host CPU source code is available to provide the ability for the device to be a DLR participant or a DLR supervisor using the DLR support functions. The fido2100 will default to linear topology operation, and when inserted into a ring, will automatically change to DLR operation as a DLR participant.
