General
|
Security / Fixes
• This version contains several security enhancements. Updating to this version of the product is strongly recommended.
• User permissions have been added for controlling access to the Event Log relevant to security, error, warning, and informational messages.
• Compatibility validated for Windows 11 and Windows Server 2022
• Fixed an issue where the device level _ActiveTagCount system tag was not updating correctly.
• Updated Licensing Tools to fix intermittent memory corruption issues.
• Fixed an issue that would cause the configuration window to hang during project validation.
• Updated handling of OS shutdown notifications to allow more time for Kepware services to terminate during OS shutdown or reboot subject to Microsoft’s Pre-shutdown notification process.

Configuration API
|
Endpoints / Security
• Added an About endpoint to provide version information about the server. This returns the product ID, product name, and version number.
• Added the ability to filter results from the event log endpoint by event type. See the help file for more information on query parameters.
• Changed the default ordering of event log results returned over the Configuration API. Previously, it returned the most recent page (default 100 events) sorted in oldest first order within the JSON array. It now returns the most recent page sorted in newest first order within the JSON array. This is meant to provide a more intuitive experience when transitioning between pages.
• Removed notifications in the event log showing user logins via the Configuration API. This information is persisted in the Configuration API transaction log.
• Changed the default mode for the Configuration API transaction log to single file.

Deprecated
Deprecated this driver. Existing OPF project files load, but the channels present an error in the event log. Existing JSON project files fail to load with an error message.
|
IEC 61850 MMS Client
|
Automatic Tag Generation (ATG)
Fixed an issue that would cause the first automatic tag generation attempt to fail, but succeed thereafter.
|
IoT Gateway
|
Array Tags / Send Every Scan / Clients

Mitsubishi Ethernet
|
Monitor Properties
Fixed an issue where the Monitor Interval (s) property could be specified even though a Monitor Item was not set.
|
Modbus Ethernet
|
_error Tag
Modified the _error tag to only toggle based on device communication status.
|
MTConnect
|
CURRENT Command
• Added the ability to issue a CURRENT command without a path and added a property in device properties to enable this without changing the behavior of existing projects.
• Increased maximum channels to 1024 (from 256).
|
ODBC Client
|
Stored Procedure
Fixed an issue where stored procedure OUT string parameters were not cleared before the stored procedure was executed.

OPC DA Client
|
Rejected After Restart
Fixed an issue where item adds were rejected after a server restart.
|
OPC UA Client
|
Filtering
• Removed the ability to filter browsing results.
• Added support for continuation points when browsing for tags. This allows the driver to browse in smaller chunks and avoid timeouts related to server processing time when the server has a very large number of items.
|
OPC UA Configuration Manager
|
Security & Certificates
• Added a new OPC UA Security Policy (Basic256Sha256) available for server endpoint configurations.
• Updated the default Security Policy to use most secure (Basic256Sha256) and to use the message mode of “Sign and Encrypt”.
• Updated the UI to show Security Policies that are deprecated (Basic128Rsa15, Basic256, None).
• Updated instance certificate signature algorithm to use sha256RSA for new self-signed certificates.
• Changed the instance certificate expiration from ten (10) years to three (3) years.
• Added a pop-up message to warn users when trusting certificates using an unsecure signature algorithm.

• Added support for reading and writing to the Siemens TIME data type as a Long (DINT) in the server.
• Added support for reporting controller information in the event log on connection:
◦ IP Address
◦ Controller Series
◦ CPU Type
◦ Firmware Version

• An event message is posted to the event log when the driver loads symbols from the controller.
• An event message is posted to the event log when either a connection limit is reached or per connection memory limit has been reached.
• An error code is now posted to the event log when an array tag’s array range is invalid.
• Reduced symbol load time as well as memory usage per connection. IDB/FB symbols are no longer loaded and cannot be accessed.
• Fixed multiple issues pertaining to resource usage when loading symbols from the Siemens controller.
◦ Fixed an issue where the application was terminating unexpectedly.
◦ A unique error message FFF0000C or Connection closed by device is reported in the server’s event log when a Siemens controller connection limit is reached. Previously this may have displayed as FFFB00C9 or Unsupported communications configuration detected.
◦ A unique error message FFF00005 is reported in the server’s event log when the application exceeds its memory limitations. Previously this may have displayed as FFFB00C9 or Unsupported communications configuration detected.
