Security / Terminology / Redistributables
• Security improvements are implemented in this version.
• The installer now installs Visual Studio 2015-2019 C++ redistributables and the product uses them as its primary dependency.
• Updated terms considered non-inclusive out of respect for users of our software in the following drivers and suites: Modbus Unsolicited Serial, Siemens TCP/IP Unsolicited Ethernet, Fisher ROC Ethernet, Fisher ROC Serial, Fisher ROC Plus Ethernet, Fisher ROC Plus Serial, AutomationDirect EBC, SIXNET UDR, and Weatherford.
• OpenSSL has been updated to version 1.1.1i to address CVE-2020-1971.

|
Dead Lock
Fixed a dead lock that could occur between AsyncIO2::Refresh2 and IOPCSyncIO::Write calls.
|
|
Expire Sessions / Crash Fix
• Fixed an issue where the server could expire unactivated sessions before the client could activate them and BadSessionIdInvalid would be returned from the ActivateSessionRequest when the client would attempt to activate.
• Fixed an issue where certain interface requests could crash the runtime.
|
|
Logging / Timeouts
• Enhanced diagnostic logging functionality consistent with OPC diagnostics and communication diagnostics.
• Diagnostic Log settings are accessed in the Logging property group of the project and the Event Log tab of the Server Administration.
• Windows socket timeouts were added to prevent OpenSSL functions from hanging due to dropped packets.

Firmware V33
Added support for ControlLogix firmware V33, which includes support for CompactLogix 5380 and ControlLogix 5580 P-controllers (PlantPAx Distributed Control System).
|
|
Deprecated
Deprecated the driver, which contained library dependencies linked to operating systems deprecated by Microsoft. 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.
|
|
Terminology
Removed non-inclusive terms out of respect for users of our software.
|
|
Store and Forward
Added code to prevent store and forward files from being corrupted.
|
|
Wildcards
Added EFM wildcards for ContractYear, ContractMonth, ContractDay, ContractHour. These wildcards create values relative to the contract hour set in the device (i.e. if the contract hour is 6, the 6AM record will display as hour 0).
|
|
New Calls
• Added support for the cnc_rdtimer call to allow reading five different timers from the device.
• Added support for the cnc_rdalmmsg call to allow reading current alarm information; including number, type, and message.
• Fixed an issue where trying to read the cnc_exeprgname_Name tag could lead to a crash.
|
|
Terminology / History Timestamp / K-Factor
• Removed non-inclusive terms out of respect for users of our software.
• Added a History Timestamp property to the EFM Meters property group, allowing users to specify whether the device-provided timestamp is Leading or Trailing.
• Fixed an issue causing the EFM Exporter to report the incorrect Volume Units for K-Factor.

|
ApplicationID
Fixed an issue where incorrect ApplicationID values could be input into the device configuration. ApplicationIDs with less than three numbers are no longer allowed.
|
|
REST Client Agent / Lock / MQTT Client Agent
• Fixed an issue where REST Client Agent expansion message error messages could be empty.
• Fixed an issue in which caused failed authentication could cause the IoT Gateway service to lock up.
• Clarified event log message posted when the event buffer is full for REST Clients and MQTT Client Agents.
|
|
Monitoring Timer
All requests now include a Monitoring Timer value to support timeout issues when multiple devices are networked together.
|
|
Null Terminator
Fixed an issue where a random character could appear after the null terminator in the final word of even-length string writes.
|
|
Terminology
Removed non-inclusive terms out of respect for users of our software. Renamed this driver in compliance with updated terminology.
|
|
Skip Schema Validation / Device Discovery
• Added a property that allows users to skip schema validation.
• Fixed an issue where removing all the devices under a channel then performing a device discovery could lead to a crash.
|
|
Liquid Orifice
Fixed an issue where some liquid orifice meter data wasn't exported correctly.
|
|
DA 3.0 Writes / Tag Subscription / Rebuild Connection
• Fixed an issue that prevented successful DA 3.0 writes.
• Fixed an issue when trying to write to tags before they are added to a subscription.
• The driver rebuilds the connection if the device level group fails to add, similar to a shutdown notification, status, or watchdog failure.
|
|
UTF-8 Encoding / Subscription
• Fixed an issue where the driver was not correctly handling UTF-8 encoding.
• Fixed a communication break when receiving invalid or empty subscription handles from the server.
|
|

Fixed an issue where the driver was unable to write to tags with an initial quality of uncertain.
|
|
Status Tag / RoundTripTime Tag
• Fixed an issue where the Status tag did not always update on clients when changing from 1 (ping successful) to 0 (ping failed).
• Added code to update the RoundTripTime tag value correctly when it is the only valid tag.
|
