AC500 High Availability

Performance is the key
Most downtime is caused by either human error or device
malfunction which could be avoided with the AC500 high
availability. Utilizing dual CPUs and dual distributed I/O Bus OPC server
help reduce any risk of total system failure thus enhancing
system availability.
If the retention of critical data and the avoidance of downtime DigiVis500
are important to your application then ABB AC500 high avail- Supervisory control
ability with dedicated large data storage solution is the ideal
solution.
What benefits can you expect from our AC500 high availability
solution?
– Greater resource usage with no downtime in hardware/ Ethernet
software failure with the dual CPUs and dual communica-
tion fieldbus CS31-Bus
– Cost efficiency and easy system maintenance through the
use of standard hardware
– Only standard CPUs required, choose from PM573-ETH to Automation Builder software CP600 HMI
PM592-ETH to achieve high availability suite
– 3 cycles or 50 ms changeover time (no cycle synchronized
Hot-Standby)
– Up to 8 additional redundant IO-Bus lines via CM574
possible (1).
(1) available after Q2/2014.
