The AC 900F controller consists of a CPU module, which is the main component. According to the application and requirements, fieldbus modules and I/O modules can be added to the controller. Optionally, AC 900F supports redundancy.
The AC 900F consists of:
Plus CPU module PM 904F who expands the capability of the Standard version PM 902F and supports up to four communication interfaces for PROFIBUS or CAN as well as more application memory.
Standard CPU module PM 902F with four Ethernet interfaces, one diagnostic interface, two serial interfaces and display unit (optional). It supports up tp two communication interfaces.
Lite CPU module PM 901F with three Ethernet interfaces, one diagnostic interface, two serial interfaces and display unit (optional). It supports up to two communication interfaces.
Up to ten S700 I/O modules directly attached on terminal units
The controller supports remote I/Os, transmitters, actuators, drives and other devices, for example through PROFIBUS and other fieldbus protocols.
More power than any previous generation controller
Up to four (PM 904F) or up to two (PM 902F/PM 901F) communication interfaces for PROFIBUS or CAN
Connectivity with 2 serial ports and 4 Ethernet ports (3 with PM 901F)
SD card support for easy controller backup and firmware update
Ethernet based protocols: Modbus TCP, IEC 60870-5-104
G3 compliant for use in harsh environments
Optional LCD for easy access to status and diagnostics information
Small footprint
Optional redundancy for higher availability
