Enhancements and Improvements

Description
DeviceHub: The Siemens S7 driver now supports defining a maximum Protocol Data Unit (PDU). This enables you to adjust the PDU limit in cases where the driver requests data with a PDU that exceeds the limit of a PLC. With the OPC UA Client Advanced driver, now the timestamp in tag payloads reflects the OCP UA serverTimestamp when Driver Mode is set to Subscription and Additional Parameters are enabled.
Integrations: A validation action has been added when deleting an integration. Now you must enter the connector name to confirm the connector that you are deleting. This matches the behavior for deleting a device in DeviceHub for a consistent user experience.
System Settings: You can now update Maximum Transmission Unit (MTU) settings in the UI in System > Network > Interfaces. Change MTU settings to resolve network communication issues, for example between Litmus Edge and Litmus Edge Manager.

Resolved Issues

Description
DeviceHub: Fixed issue where the Keyence Nano Ethernet (Gen1) driver failed to write data to certain bit registers, for example to EM_bit, MR, B, and others. Fixed issue where a tunnelling connection device with Emerson DNP3 with FB Extensions driver failed to reconnect after the device was rebooted. Fixed issue where data values became associated with the wrong tags when a network issue, such as a disconnection, occurred with device connected with the Mitsubishi Q/L Ethernet driver. Fixed issue that occurred with S7 CommPlus drivers where UDTs and FBs do not share unique ID space
Digital Twins: Fixed issue where a "static attribute key is not unique operation not permitted" error occurred when updating a model containing dynamic and static attributes with the same name.
Integrations: Fixed issue where connecting to Litmus UNS through the Litmus UNS connector on Docker deployments failed and a "network Error : dial tcp: missing address" error occurred.
