Summary AB 1756-CNB/A
The 1756-CNB is an Allen-Bradley ControlNet bridge that can be used to communicate within control networks. Unlike other communication modules in the 1756 series, the 1756-CNB uses either a standard or non-redundant configuration. If the users’ application contains 40 to 80 Logic connectors per every single module, then the 1756-CNB is an ideal option. With a communication rate of 5 megabytes per second as well as 99 nodes, this Allen-Bradley communication module gives superior speeds to industrial projects. The 1756-CNB does two things: controlling the I/O data—especially when it is used with the Logix5550 co ntrollers for both scheduled and unscheduled data and bridging data that travels between ControlLogix backplanes as well as ControlNet Networks. Make sure that the path information is correct to properly route the messages it receives. |
