Setup Guidance\u003c\/h2\u003e\u003cp\u003eInstall the 1756-RM2 in any slot of a ControlLogix chassis. When implementing redundancy, you must use a pair of redundant racks, each with the same controller type and revision. Note that I\/O modules, intelligent modules, and Encompass partner modules cannot be installed in the redundant chassis pair; place them in a third or higher-order chassis as needed.\u003c\/p\u003e\u003cp\u003eConnect the two 1756-RM2 modules using the appropriate fiber-optic cable (1756-RMC1, 1756-RMC3, or 1756-RMC10) with LC-type connectors. The modules can be up to 10 km apart, but for optimal performance, keep the redundant chassis pair in close proximity.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRegularly inspect fiber-optic connections for cleanliness and proper seating. The module's open enclosure allows for adequate airflow, but ensure the chassis environment stays within the specified operating temperature (0-60 °C). Periodically verify synchronization status and diagnostic LEDs to detect potential issues early.\u003c\/p\u003e\u003cp\u003eBy adhering to these simple maintenance practices, you extend the life of the 1756-RM2 and maintain high system availability, reducing long-term operational costs.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eThe 1756-RM2 supports ControlLogix 5560 and 5570 controllers. It also supports up to seven enhanced ControlNet and EtherNet\/IP communication modules, allowing seamless integration into existing networks. Use the Redundancy Module Configuration tool (RSLinx 2.59 or later) to configure and monitor the redundant system.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing, verify that your controllers are from the 5560 or 5570 series and that you have the required fiber-optic cables (1756-RMC1, 1756-RMC3, or 1756-RMC10). Ensure your chassis has an available slot, as the 1756-RM2 occupies one slot.\u003c\/p\u003e\u003cp\u003ePLC Source PRO offers genuine Allen-Bradley 1756-RM2 modules with reliable availability and competitive pricing.
