AC 900F Controller Section 1 Overview
12 M&I – AC 900F Controller
The AC 900F comprises the following components:
• PM CPU module with
– PM 902F: four Ethernet interfaces
– PM 901F: three Ethernet interfaces
– one diagnostic interface
– two serial interfaces
– one TD display unit (optional)
• up to ten S700 I/O modules with I/O terminal blocks
• max. two CI/CM fieldbus communication interfaces
The controller can be used in single or redundant configuration. It supports remote
I/Os, transmitters, actuators, drives, and other devices using PROFIBUS and other
fieldbus protocols. ABB offers a wide range of different devices and
network components for applications in standard and hazardous areas.
In the present version, the AC 900F controller supports the following fieldbus
technologies:
• PROFIBUS-DP V0/V1
• Modbus RTU (serial) and Modbus TCP
• Telecontrol protocol (serial) and Telecontrol TCP
• ABB CAN Bus protocol
Depending on type and number of process signals, input/output modules are used
either as “direct” I/O or as remote I/O. For more detailed information on assembly
and installation of I/O modules, please refer to Mounting and Installation
Instructions, I/O Modules for AC 700F / AC 900F.
Similar to the AC 700F and AC 800F, the hardware configuration of the AC 900F is
based on the hardware function block principle.
The AC 900F controller is designed for the combination with fieldbus-compliant
components like remote I/O, field devices and network components. ABB offers
equipment for applications in standard and hazardous areas.
