The firmware contains general product quality improvements and is used to upgrade devices of the above-mentioned products that are already in use.

In particular, the firmware contains the following changes:

Feature Enhancements:

DNP3 - Point-to-Point Connection to Third-Party Devices

• Achieve effortless interoperability with diverse third-party devices, ensuring a smooth and reliable communication network. This feature allows for seamless integration into existing systems, reducing downtime and enhancing overall operational efficiency.

Optimized Event Buffer Clearing

• Maintain optimal system performance with optimized event buffer clearing. This ensures that your system remains responsive and efficient, preventing data overload and ensuring that critical events are always prioritized and processed in real-time.

DNP3 - Negative Acknowledgment for Time Synchronization Requests from Unauthorized Partners

• Enhance your system by preventing unauthorized time synchronization requests. This feature ensures that only trusted partners can synchronize with your system thus protecting your network.

IEC 60870-5 - Support for Originator Address

• Facilitate precise identification and tracking of command originators, improving accountability and traceability within telecontrol system.

IEC 60870-5 - Support for COT11/12

• Ensure comprehensive support for Cause of Transmission (COT) codes 11 and 12, enhancing the reliability and accuracy of your data transmission processes.

IEC 60870-5 - Support for Multiple TCP Ports

• Increase flexibility and scalability by supporting multiple TCP ports, allowing for more robust and adaptable network configurations and enhanced connection capabilities with Scada Systems.

Extended Time Tab in Online Diagnostics

• Gain deeper insights into system performance with an extended Time Synchronization Information in online diagnostics, enabling more detailed analysis and quicker troubleshooting.

Time Stamp Validity in NTP with TeleControl Applications

• Ensure accurate and reliable time synchronization with Network Time Protocol (NTP), maintaining the validity of time stamps and enhancing the precision of your telecontrol operations.

Bugfixes:

• Fixed an issue where Cyclic restart occurs even if the 'Cyclic restart' option is disabled
• Fixed an issue that IEC Data points are no longer automatically transferred after PLC STOP/RUN

Security fixes:

• OpenVPN ≤ 2.6.10
  several vulnerabilities fixed in 2.6.11
• Siemens miniweb 8.2.0 ≤ 9.1.0
  Remote Denial of Service Vulnerability

To utilize the new "Functional extensions," customers are required to configure their modules to operate on offline version V3.6 or later. For CP1200 modules, the requisite TIA version for offline V3.6 compatibility is TIA V20.
