Security updates and performance improvements
  • Security updates – UniInt leverages the latest Microsoft software security defenses provided by the compiler and operating system.
  • Least privileged account support – Interface services are now allowed to run under an account with the least privileges required, and limit the rights of the account to access resources.
  • Improved performance - on disconnected startup point caching.
Release
PI Interface for OPC Alarms and Events
1.5.4.267
2012-05
This release features new and improved failover options, improvements to message logging and bug fixes.
New Features: • New option for cold failover – allows a node that was primary and had a bad status the opportunity to regain good status and become primary again without a restart.
 New options for failover - where there is both PI Interface failover and data source (a.k.a. server) failover.
• Improved message logging - the extraneous messages showing connect retry attempts has been reduced to only printing out the error message.
 Hot failover now supports archive writes – and data is no longer rejected when a lot of data is sent to PI with the same timestamp.   Bug Fixes: • Lock up condition has been fixed – condition could occur when multiple interface instances were running.
