Programmable automatic controller, suitable for high reliability control application in process industryThe rich function application library contains a variety of control circuit types, such as advanced control and self-tuning functions, and integrates ABB drive and motor applications. The controller communication includes the built-in rnrp redundant communication based on Ethernet and the connection of various communication modules to third-party equipment. The advanced redundancy concept can ensure fast switching between controllers and flexible topology. A variety of CPU types are available, and the processing performance, memory size and redundancy functions can be flexibly selected. Priority based and cycle based tasks can ensure the highest stability even in the case of complex control tasks.The programming tool is compact control builder, which supports the programming language of Standard IEC 61131-3, and can configure the control program and the hardware configuration of AC 800m. Through one database, all functions such as logic, sequence control and analog quantity control can be realized for all controllers in an automation system. Flash cards enable applications to be loaded without engineering tools for OEM and remote solutions.AC 800m is a product family, based on rail installation, including a variety of CPUs, communication modules, power supply modules and a wealth of accessories. There are 7 kinds of controllers available, ranging from the controller with medium processing performance to the controller with high performance and full redundancy. Users can determine them according to application requirements and prices.
