Section 1 Introduction
Product Overview
AC 800M – General
AC 800M can be defined as a hardware platform to which individual hardware units
may be connected and which, depending on the specific unit configuration and
operating system selected, can be programmed to perform multiple functions.
Once configured, the AC 800M hardware platform effectively becomes
the AC 800M Controller.
The hardware units that form the AC 800M Controller are:
• Processor units (including baseplate)
(PM856/PM860/PM861/PM864)
• Communication interfaces for different protocols (including baseplates)
(CI851/852/853/854/855/856/857)
• Power supply units, providing various power output levels
(SD821/822/823)
• Battery back-up unit
(SB821)
When equipped with the specified Control Software, the AC 800M Controller will
act either as a stand-alone process controller, or as a controller performing local
control tasks in a control network consisting of many interconnected controllers,
operator stations and servers.
Various I/O systems can be connected to the AC 800M Controller, either directly
(S800 I/O) or via PROFIBUS DP or PROFIBUS DP-V1.
The AC 800M is delivered without Control Software. To provide the controller
with Control Software it will first be necessary to load the firmware and create
the application separately using the Control Builder M engineering tool.
