• Fixed an issue where deadlock could occur if multiple pieces of outgoing data were queued while the driver was still processing incoming data. This change affects the Transmit and Transmit Byte Commands.

• Fixed an issue where data loss could occur if there was still data on the wire from a previous transmission when either a Transmit or Transmit Byte command was called.

• Added logic to handle writing packets larger than 1024.

• Added support for the CRC-8 Checksum, which is listed as "Custom #15 (8-bit)." The checksum's CRC polynomial is: x^7 + x^3 + 1.

Added the new custom check sum "Custom #14 (8-bit)". The check sum is determined by subtracting the valid hex numbers and the ASCII values of non-valid hex numbers from 0x00, and then swapping the Hi and Low nibbles.

• Fixed an issue where the configuration client would crash when the driver attempted to automatically generate tags while disconnected from the Runtime.

• Prevented a deadlock issue that could occur if multiple pieces of outgoing data were queued while the driver was processing incoming data. This change affects the Transmit and Transmit Byte Commands.

• Fixed an issue where the "Update Tag" command no longer fails when used in an unsolicited mode tag and the tag type is "Dynamic ASCII Format".

• DWord tags that use "ASCII Integer" or "ASCII Integer (packed 6 bit)" now support the full DWord range.

• The "Update Tag" command now updates a numeric data tag that uses the "Byte from 2 ASCII Hex Chars (hh)" or "Nibble from 1 ASCII Hex Char" format.

• Fixed an issue where transaction commands were unavailable from the Edit menu if the Transaction window was selected.

• Increased the character limit for Tag Group Names and Tag Names to 255.

• Added the new Custom Checksum "Custom #13 (8-bit)". This checksum sums the bytes and then subtracts the sum from zero.

Fixed high CPU utilization in the Server Runtime caused by the U-CON driver when using cached Write Value commands in unsolicited Ethernet encapsulation mode and no socket connection exists.

• Fixed the ASCII/Hex ASCII encoding for the existing Date/Time formats and added new Date/Time formats. The new Date/Time formats include the following:
• Added the Seek String Command. Reworked the Test String and Write String commands to support all the string formats that are supported by the driver.
• The Event Counter is now stored as DWord. The Update Tag can update the tag with the value of the Event Counter for 8, 16, and 32-bit Intel data formats.
• The Write Event Counter command now supports various 32-bit formats for writing the DWord Event Counter.
• Added "Use Current Buffer Position" checkbox controls to the following commands: Test Device ID, Test String, Test Character, Test Check Sum, Test Bit Within Byte, and Compare Buffer.
• Resolved an issue where the driver was failing to send closely-timed Transmit commands while using Ethernet Encapsulation.
• Fixed an obscure issue where a temporary buffer used by the state machine of one channel could be overwritten by the state machine of another channel which resulted in erroneous updates of certain tags. State machines now use independent and thread safe buffers to prevent this problem.

• The driver will now check for License Activation upon receiving unsolicited communications.

• Fixed issue where projects created in server/driver version 5.3 that used WriteDeviceID and WriteEventCounter commands would fail version comparison and not load the project in 5.4.
• Fixed an issue wherein legacy .opf projects saved as xml would fail to pass schema validation.
• Modified Transaction Editor Write commands, and also added Data destination radio buttons for Read, Write, Scratch, and Global buffers for commands CmdWriteDeviceId, CmdWriteEventCounter, and CmdWriteCheckSum.
• Increased the Device ID value limit from 255 to 65535.
• The Transaction Editor posted an incorrect validation message when creating a Cache Write Value command without a preceding Transmit command. A Write Data command is required before a Cache Write Value command. A Transmit command is not required. Both the validation and error message have been updated.
• Fixed an issue wherein the driver sometimes failed to respect signed data types if the device data format had fewer bytes than the data type. Signed data types would not correctly display negative values. The driver now always respects whether the data type is signed when converting to and from the device format.

• Fixed issue where the Invalidate Tag command would not invalidate tags inside of a Tag Block.
• Added support for Custom #12 (8-bit) checksum. This is a variation on the Sum (8-bit) Check Sum. Input data is assumed to be in Ascii Hex. Data is converted to hex before sum. The sum is then subtracted from 0xFF.
• Added model to support string based IDs. The model affects the formats available in the Write Device ID command and the Test Device ID command.
• ASCII Real and ASCII Real (packed 6 bit) format property pages have been modified to be more user-friendly.
• Fixed issue where Function Blocks and Global Buffer Preset were saved as part of an xml server project but were not available in the project when reloaded.

• Added ability to select any character as the escape character for a selected group of control characters to the Handle Escape Character command.
• Fixed issue where format properties for commands were not preserved in the transaction editor on loading a command's properties.

• Fixed issue where Transmit Byte command and Clear Rolling Buffer command were allowed to be selected from the menu without selecting a transaction in the item view.

• Fixed issue where the Event counter was not incrementing for unsolicited transactions when as command preceded the initial read response.
• Fixed issue with ASCII Real and ASCII Real (packed 6-bit) formats where legacy projects failed to load a default value for the "Use decimal comma in place of decimal point" option in the format properties. This resulted in projects behaving as though it was set even though the check box was not marked. Viewing the dialog box would set the property to the default value (unchecked/false).
• Fixed issue with ASCII Real and ASCII Real (packed 6-bit) formats where non-negative numbers with negative exponents only displayed the exponent.
