Improved Accuracy
Improved the accuracy of running processes.
|
OPC UA Interface
|
ReceiveBufferSize
Resolved an issue where the server could send packets that exceeded the ReceiveBufferSize negotiated with the client in the OPC UA TCP Hello message. Fixed an issue where the server failed to provide a product URI when registering with a Local Discovery Server.
|
Server Runtime
|
_Simulated System Tag
The device-level system tag _Simulated has been changed from Read-Only to Read/Write to facilitate control of polling.
|
ThingWorx Native Interface
|
Store and Forward
Added support for Store and Forward to the ThingWorx platform. The server can be configured to store updated property data to disk when disconnected from the ThingWorx platform and then send that data gracefully when the connection is re-established.

ABB Totalflow
|
Updates
• Increased the maximum EFM meter count to 128.
• Fixed an issue where the _PercentValid and _PercentReturn advanced statistics tags were not displaying valid results.
• Now correctly handles Trend File Tags where the file name contains a period/dot '.' character.
|
Allen-Bradley ControlLogix Ethernet
|
Updates
• Resolved issue with loading old default values of Array Count Upper Limit.
• Fixed a problem with automatic tag generation from projects containing a structure with "hidden" in the name.
|
CODESYS
|
Tag Browser
A fully featured tag browser is now available to allow users to add tags to server projects without manually creating them. The browser is available for use in the Configuration interface as well as over the Configuration API Service.
|
DataLogger
|
Table Validation
Enhanced to treat table validation errors as recoverable and continue table validation attempts until successful.
|
EFM Exporter
|
c_prime
Changed PGAS Exporter to export flowing_condition_factor into the c_prime column if there is no value for the c_prime attribute.
|
Enron Modbus
|
Updates
• Improved the clear cache logic to allow retrieval of all entries when applied.
• Added support for zero-based archives for customers using Fisher ROC devices with this driver.
• Fixed an issue where EFM records at the beginning and end of an archive might not be retrieved.
|
Fisher ROC Ethernet
|
Updates
• Fixed an issue where automatic tag generation for Point Type 7 and Point Type 10 would result in generating tags for Logical Point 0.
• Added validation for data length, starting log pointer, and history point number to prevent re-sent packets from being processed again.
• Fixed an issue where a K Factor value could be exported as Cutoff instead of Nominal K Factor.
• Updated the parameter size for parameter #0(Device Tag) in Point Type 177's address table from 10 bytes to 40 bytes.
|
Fisher ROC Plus Ethernet
|
Point Type 177
Updated the parameter size for parameter #0(Device Tag) in Point Type 177's address table from 10 bytes to 40 bytes.
|
Fisher ROC Plus Serial
|
Point Type 177
Updated the parameter size for parameter #0(Device Tag) in Point Type 177's address table from 10 bytes to 40 bytes.

Local Historian
|
Value Display
Fixed an issue where historized values would not display in the item’s Value Display window.
|
Modbus ASCII
|
Station ID
Resolved an issue where the driver could incorrectly respond to transactions that did not match the station ID.
|
MQTT Client
|
New Driver
Initial release of the MQTT Client driver with the capability to connect to an MQTT broker and a specified Topic. The driver parses any valid JSON messages that are published to the Topic and update tags based on that data. This is a read only driver; it is unable to publish data to a Broker. The driver is configured in the Connectivity node of the Project Tree.
|
|
Localization
The MQTT Client driver is localized for Japanese, German, and Chinese cultures (simplified Chinese).
|
OMNI Flow Computer
|
Clear Cache
Improved the clear cache logic to allow retrieval of all entries when applied.
|
OPC XML-DA Client
|
Security
Disabled support for all versions of SSL/TLS older than v1.2. This change affects users referencing HTTPS Security in the server endpoint URL.
|
Siemens TCP/IP Ethernet
|
Updates
• Added support for larger PDU sizes of 480 and 960.
• Added a new setting called Maximum PDU Size. The driver and device negotiate the highest supported PDU size by starting at this defined setting and no higher. Available PDU sizes include 240, 480, and 960
|
Siemens TCP/IP Server Ethernet
|
Updates
• Added support for larger PDU sizes of 480 and 960.
• Added a new setting called Maximum PDU Size. The driver communicates using the PDU size defined in this setting. Available PDU sizes include 240, 480, and 960.
|
SNMP
|
Registering Tags
Fixed an issue where, in certain applications, the driver could hang when registering tags to clients.
|
Toyopuc PC3/PC2 Ethernet
|
Retry Attempts
Changed the driver to use the Retry Attempts setting in the Timing group of Device Properties as the total number of attempts.
