Serial latency: how many devices? Up to 32 devices in a daisy-chain can be sensibly deployed in an industrial setting. Theoretically there could be dozens of device deployed in a chain through use of store and forward technology ¨C used by both daisy-chain devices and standard Ethernet switches. This assures that each packet is checked for accuracy before being forwarded on the network. The cost of that accuracy is 20-40¦Ìs latency for the average automation protocol message passing through each device. This means that the total time it takes for a message to travel from the first device in a chain of 32 to the last device would be less than 1.3ms absolute worst case.
