The SynqNet Hot Replace feature allows one or more consecutive nodes to be shut down, serviced, and then reattached to the system without affecting the operation of the other nodes.

The Cyclic Redundancy Check (CRC) is a way of detecting small changes in blocks of data. This type of error detection is especially useful when sending packet data across a SynqNet network.

During SynqNet Network Initialization, the network is discovered, the topology is tested for an exact match to the expected topology, the network is transitioned to cyclic operation (SYNQ mode), and the nodes are initialized. Watch a sample network as it goes through each step.

The Packet Error Counter checks for missing or invalid packets over a SynqNet network. There are packet error counters on the controller and node(s), which monitor upstream and downstream communication.

The Packet Error Rate Counter is in charge of tracking the rate of packet errors per SynqNet cycle. The Flash animation provides an overview of its functionality and how the rate counter can increment and decrement over time.

If the Packet Error Rate reaches the FAULT limit, the network will attempt a SynqNet Fault Recovery (for Ring topology only). If the Packet Error Rate reaches the FAIL limit, the network will shutdown.

The SynqNet Fault Recovery feature allows the network to use the idle link for correcting faulty communication without having to perform an emergency shutdown of the network.

A SynqNet Failure occurs when a node on the network reaches its FAIL threshold. Watch what happens when the FAIL threshold is reached on a String topology.
