REDUNDANCY HOT STANDBY
Complete Redundant System Architecture
The redundant system below, shows different functionalities with redundancy, as it will be seen
below.
Figure 7.1 – Redundancy Architecture Example of the MB-700
The functionalities with redundancy are:
•
Supervision Workstations: The application shows two supervision workstations, which can
monitor variables/tags of the MB-700 module;
•
Ethernet Network: Each supervision station has two boards, each one in an Ethernet network,
using different switches. Thus, even if there was trouble with one board or net cable, or a
supervision station switch, it will stay in conditions to keep the supervision, beyond to be available
the other supervision station;
•
Redundant Source and Backplane: Each MB-700 has its source and backplane and, although
the application above does not show, it already is possible to do power supply redundancy for each
MB-700;
•
Redundancy of the MB-700 Module: How the MB-700 module is responsible for all store and
control of the information interchange between Modbus slaves, the redundancy of this module
assures the availability of the supervision and control system functioning without interruption;
•
Diagnosis: Through the MB-700 transducer parameter monitoring can be tracking the possible
failures which are on the system.
