ABB controller Both Compact Control Builder and 800A control builder can be used to configure AC800M. With Compact Control Builder configuration, AC800M can be used in all control solutions. With 800XA Control Builder configuration, AC800M becomes a part of tight integration on 800XA DCS and can be used as an attachment of 800xA system.   AC 800M CPU module Various CPU modules can provide different functions, processing capacity, memory and redundancy support. Each CPU module is equipped with one or more Ethernet ports to exchange data with different controllers or interact with operators, engineers, managers and higher level applications. When availability becomes the most important, these Ethernet ports can be configured as redundant. Each CPU module is also equipped with two RS-232C ports, which can exchange point-to-point data with programming/debugging tools or third-party systems and devices.   Com and I/O module For each CPU module, multiple communication and...
