NHP Electrical Engineering has extended the functionality of its Adroit SCADA (Supervisory Control and Data Acquisition) package to include hot standby, or full redundancy.
Enhancing Adroit's advanced server capabilities, the additional functionality offers full shadowing of operator actions, including alarm acknowledgment and set point changes.
Hot standby protects data integrity and prevents interruptions to processes.
Known as Adroit Active Clusters, the new feature is included within the standard Adroit package and is simple to set up, requiring no scripting or additional software.
Following the fail over of a server and recovery, the Adroit cluster synchronises at three levels: real time clock to synchronise the time between servers in the cluster; real time data to synchronise real time data coming from the plant, and historical data to fill in gaps in the history files.
Brett Ginsberg, HMI product manager at NHP, said Adroit already supported redundancy at the hardware level, supporting dual communications to PLC devices with dual ports.
