PM802F  AC 800F Controller Redundancy

AC 800F opens up the flexibility of Fieldbus technology to the user. The AC 800F collects
and processes diagnostic and process data
from four Fieldbus lines, which may be of different types. It does this in addition to the tasks of a “conventional” process station.
The AC 800F is available in two versions:
• 4 MB static RAM, 4 MB EPROM
• 16 MB synchronous dynamic RAM, 8 MB EPROM
Up to 4 (different) fieldbus modules can be plugged into the AC 800F. The communication
with other controllers runs via Ethernet.
The AC 800F optionally provides several levels of redundancy:
• device redundancy with 2 AC 800F
• power supply redundancy (24 V DC)
• Ethernet communication redundancy (standard)
• Cable redundancy for Profibus DP, requires external equipment (RLM01)
The data protection is made via battery back-up by Ethernet or battery modules with appropriate functionality.

Controller redundancy can be achieved by installing two
AC 800F. To ensure quick and smooth takeover by the secondary AC 800F in case the primary AC 800F fails, a dedicated
redundancy communications link through the second Ethernet
module makes sure that both AC 800F are always synchronized. All inputs and outputs are designed to support redundant
operation.
