PI Interface for ACPLT/KS



With this release, the PI Interface for ACPLT/KS is now available in two different options: a new read-only option and an update to the already-existing read-write option.

The read-only option is strongly recommended for installation if updates to the data source are not needed (that is, it does not allow output points). The read-only option provides the best defense against accidental or malicious changes to the control system because it cannot write to the data source.

The read-write option retains the ability to write data to the data source (using output points) and is an update to previous installations of this interface.

For more information on these two interface options and how to switch from the read-write option to the read-only option, please see the Read-only versus Read-write Interfaces FAQ document.


New Features


  • Improved automatic recovery when neither of the referenced ACPLT/KS servers is reachable – a startup parameter has been added that may be configured to disable writing NO DATA digital state.
  • Less nuisance failover due to data calls longer than 10 s - timeouted calls have been implemented to the ACPLT/KS Server.



UniInt Enhancements


  • Security updates
  • 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.
