The 1756-RM2 is classified as a Remote I/O ControlNet Adapter module. ControlNet is a high-speed, deterministic industrial network protocol used for connecting various devices in a control system. The module acts as a bridge between the ControlLogix processor and the remote I/O devices connected to it.

The 1756-RM2 module can be installed in the ControlLogix chassis and integrated into the system as one of the communication modules. It communicates with other ControlNet devices via a ControlNet network, allowing the ControlLogix processor to exchange data with remote I/O modules located in different parts of the control system.

The module supports various ControlNet features, including flexible I/O addressing, deterministic data transfer, and redundancy capabilities. It facilitates efficient and reliable communication between the ControlLogix PLC and remote I/O devices, enabling control and monitoring of distributed processes.
