Thanks to the use of the proven Ethernet technology, industrial networks have become very robust against interference. Nevertheless, also Ethernet based industrial networks require the possibility to have a quick and easy to use trouble-shooting access in case of disturbance.
To eliminate the need of performing network disruptions, the netMIRROR Test-Access-Point (TAP) allows continuous mirroring of the Ethernet traffic without influencing the network itself. A TAP is built in permanently, typically directly on the controllers outgoing Ethernet connection and thus allows the disruption-free connection of a diagnostic device during run-time. Additionally, TAPs ensure that a connected diagnostic device or PC for telegram capture would not interfere the network by accidentally injected Ethernet traffic.
