Release Announcement
PI Interface for SNMP is released

With this release, the PI Interface for SNMP 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.

New Features

  • Users can now configure the interface to ignore certain devices when reporting the device status - using the new /IgnoreDevice command line parameter.  This switch supports wildcards, so multiple devices can be ignored.

UniInt Enhancements

  • 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.
