The Allen-Bradley 1756-CN2RK is a member of the ControlLogix 1756 Communication Module series. The 1756-CN2RK is conformal-coated. The ControlNet Network is an open control network that is ideal for real-time high throughput applications. The networks in this module use Common Industrial Protocol (CIP). It combines I/O network functionality and peer-to-peer networks that deliver high-speed performance. The ControlNet Network gives you a deterministic and repeating transfer of all critical control data as well as supporting non-time-critical data transfers. The I/O updates and controller-to-controller interlocking have precedence over uploading and downloading programs and messaging. The Studio 5000 series supports generic ControlNet modules. This module is set up as a generic ControlNet module that deals with the controller for input, output, status, and configuration tags applications. This module has redundant configuration. The ControlNet communication rate of this module is 5 Mbps. This module has 128 Logix communication connections. The maximum number of connections supported by this module is 131. The current draw at 5.1V DC of this module is 1300 mA. The current draw at 24V DC of this module is 3 mA. The power dissipation of this module is 6.7 W.
