General
The AC 800M controller can be configured with both Compact Control Builder and 800xA control builder.

When configured with the Compact Control Builder the AC 800M is open to participate in any kind of control solution.

When configured with the 800xA control builder AC 800M becomes a tightly integrated part of the 800xA DCS. Then offered and also described as a part of the 800xA system offering.

CPU Modules
Several CPU modules are available that vary in terms of processing power, memory size, and redundancy support. Each CPU module is equipped with built in Ethernet port(s) for communication with other controllers and for interaction with operators, engineers, managers, and higher level applications. These ports can be configured for redundancy for those cases where availability is of paramount importance. It is also equipped with two RS-232C ports that can be used for point-to-point communication with programming/debugging tools and with third-party systems and devices.

Com and I/O Modules
To each CPU module, a number of communication and I/O modules can be added,
for example:

• Additional RS-232C ports
• PROFIBUS DP, DP-V1 interface
• ABB INSUM interface
• MasterBus 300 interface
• S100 I/O interface
• S800L and S800 I/O modules
