<p><b>Description:</b></p><p>Increase availability in central ship alarm systems with WAGO's Application-Based Controller Redundancy (ACR).</p><p>The licensed software library (2759-245/211-1000) and an CODESYS</p><p>redundancy framework allows you to easily program and operate redundant</p><p>master PLCs in single point of failure (SPOF) tolerant systems.</p><p>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.</p><p>These Master PLCs (2nd generation PFC200) communicate with higher-level SCADA systems, for example, via the Modbus TCP protocol.</p><p>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.</p><p> </p><p><b>Advantages:</b></p><ul><li>Easy commissioning of the entire system with WAGO’s standard hardware</li><li>Simple/slow control loops can be mapped (Alarm & Monitoring, Data Acquisition, Slow Running Processes)</li><li>Low switchover time (per marine classification society requirements)</li><li>Use of complex modules such as HART or DALI</li></ul><br/><p> </p><p><b>Benefits:</b></p><ul><li>With the application redundancy concept, WAGO provides you with a redundant framework for simple and economical system integration in ship technology.</li><li>You save engineering effort and can focus on your application.</li></ul><br/><p> </p><p><b>Licensing:</b></p><p>To use the “WagoAppRedundancyMaster.library,” a “Library Controller Redundancy Master” license (2759-245/211-1000) must be purchased for each Master PLC. An SD card image in the redundancy framework is available for the Smart Couplers.</p><p> </p><p><b>Use:</b></p><p>The license is registered in WAGO Upload and loaded onto a device. No other installation steps are required.</p><p> </p><p><b>Note:</b></p><p>Register <a href="https://www.wago.com/de/d/swreg_acr_c">here</a> to download the redundancy framework and test ACR free of charge for 30 days.</p><p> </p><p><b>Recommended Controller:</b></p><p>PFC200; G2; 2ETH RS 750-8212</p>
