ControlNet

<p>ControlNet is an open industrial network protocol for industrial automation applications, also known as a <a href="/facts/Fieldbus/kna8UpU3">fieldbus</a>. ControlNet was earlier supported by ControlNet International, but in 2008 support and management of ControlNet was transferred to <a href="/facts/Open_DeviceNet_Vendors_Association/KXjyyG9Y">ODVA</a>, which now manages all protocols in the <a href="/facts/Common_Industrial_Protocol/7D1ch1I6">Common Industrial Protocol</a> family.
</p><p>Features which set ControlNet apart from other fieldbuses include the built-in support for fully redundant cables and the fact that communication on ControlNet can be strictly scheduled and highly deterministic. Due to the unique physical layer, common <a href="/facts/Network_sniffers/mFQP7gWB">network sniffers</a> such as <a href="/facts/Wireshark/tTRY1DJr">Wireshark</a> cannot be used to sniff ControlNet packets. Rockwell Automation provides ControlNet Traffic Analyzer software to sniff and analyze ControlNet packets.
