• OPC Diagnostics will no longer be stopped when a project is uploaded or downloaded between the server configuration and the server runtime.

• A new Multiple Tag Generation tool was added to help users add a large number of tags into the server database quickly. This feature can be accessed via the "Tag Properties" page.

• Fixed an issue where a runtime failure could occur when an OPC DA client attempts to use the IOPCAsyncIO2 interface without first setting up a data callback.

• Modem functionality has been enhanced to support auto-dialing and improved phone number management.

• Fixed an issue where driver communications could be interrupted by virus scans or other processes that block access to the hard drive.

• Added text to the server's administration "Runtime Process" property page clarifying that DCOM settings do not persist when the Process Mode is changed from System Service mode to Interactive mode.

• Added support for RSLogix version v19.

• Added a new check box setting in the Logix Options page of the driver called "Automatically Read String Length". When unchecked, string reads will be optimized by having the driver bypass the LEN member read and terminate the DATA string at either the first null character encountered or the maximum string length of DATA (whichever occurs first).

• Beginning with L7x controllers, an optimization in controller memory restricts that memory cannot be accessed on a non-DWord boundary or a controller fault will occur. Because the driver was not aware of this restriction, it was possible it could fault the controller while performing Physical reads or writes. To address this issue, the driver now identifies the controller and makes the proper Physical memory access.

• Fixed an issue where tags stopped updating under certain PC environments running a multi-core CPU.

• Fixed an issue where tags have bad quality if the response to a ReadPropertyMultiple command has multiple properties listed under a single object identifier.

• Added support for discovering devices on a BACnet network.

• Added support for writing to Device Attributes (Object Group 0). This feature is required to meet the DNP WITS standard.

• Added support for writing to Data Sets (Object Group 87). This feature is required to meet the DNP WITS standard.

• The driver now supports the ability to play back Data Set snapshot data.

• New settings were added to the Device Properties page that allow for users to ignore forced flags when setting quality.

• Fixed issues with loading legacy server (.xml) project files.

• Fixed an issue where the first buffered event after startup was never displayed when the Playback Rate was shorter than the tag's Update Rate.

• A "Device Not Responding" message will no longer be reported in certain situations where the device was actually communicating.

• Added Event Log error messages for cases of incomplete or invalid responses or invalid authentication.

• Fixed an issue where the driver was reporting "Failed to initialize communication stack" in situations where serialization was enabled.

• Improved channel management when communication errors are encountered during startup.

• Fixed an issue where data set CTLS and CTLV element types were shown as having bad quality.

• Fixed an issue where Communication Serialization and Aggressive Mode Authentication were enabled.

• Added informational message to report the number of data set tags per data set added during auto tag generation.

• Added support for writing to Device Attributes (Object Group 0). This feature is required to meet the DNP WITS standard.

• Added support for writing to Data Sets (Object Group 87). This feature is required to meet the DNP WITS standard.

• Fixed an issue where data set CTLS and CTLV element types were shown as having bad quality.

• Fixed an issue where Communication Serialization and Aggressive Mode Authentication were enabled.

• Added informational message to report the number of data set tags per data set added during auto tag generation.

• Fixed an issue with unsolicited connections management and expanded the maximum unsolicited socket connections from 32 to 256.

• Added a setting that allows users to select whether the driver will close the socket on timeout.

• The driver will now check for License Activation upon receiving unsolicited communications.

• Added support for two-dimensional arrays.

• Added support for Certificate Validation when importing or trusting certificates.

• Fixed an issue where changing from v2c to v1, the "GetBulk" check box selection was not being persisted.

• Fixed a host name resolution issue where the driver was no longer receiving SNMP Traps from a device after the device's IP address changed.

• Added the ability to invalidate rather than deactivate tags that receive "NoSuchInstance" and "NoSuchObject" errors from a device agent.

• Added support for Authentication and Encryption of SNMP messages (SNMPv3 security).
