Increase availability in central ship alarm systems with WAGO's Application-Based Controller Redundancy (ACR).

The licensed software library (2759-0245/0211-1000) and an e!COCKPIT redundancy framework (LINK) allows you to easily program and operate redundant master PLCs in single point of failure (SPOF) tolerant systems.

A large number of the available 750 Series I/O Modules can be integrated into the system via Smart Couplers. These decentralized PLCs automatically recognize the input and output modules, which makes commissioning easy. The redundant communication of the two Master PLCs and the Smart Couplers is performed either via two separate networks (Dual-LAN) or a ring topology.

These Master PLCs (2nd generation PFC200) communicate with higher-level SCADA systems, for example, via the Modbus TCP protocol.

The application notes (a2020003 and a2020004) describe the practical use of the library and define the application area and the maximum number of participants within the system.
