TOP Server Release Notes (5.16.722.0) October 21, 2014

Drivers

• 
  Fixed an issue where the Auto Demotion failures counter was only reset when in a demoted state. This could result in early Auto Demotion for future communication failures.
  

• 
  Fixed an issue where device reads may be starved for a device in an error state under a channel if another device under the same channel is not also in an error state. This would prevent the device in an error state from coming out of the error state.
  
• 
  Fixed an issue where a buffer overflow could occur with writes containing 500 or more characters.
  

• 
  Fixed an issue where automatic tag generation from a *.tpy file would force all characters in the address to be uppercase. The case is now left as is in the *.tpy file.
  
• 
  Fixed an issue where generating tags with the option Only import variables marked for OPC enabled would cause the server to become unresponsive after attaching a client.
  
• 
  Corrected an issue where nested structures were not always being automatically generated correctly from a TwinCAT device.
  
• 
  Corrected an issue where tags automatically generated from a device and from an equivalent *.tpy file would result in non-equivalent projects under certain conditions.
  

• 
  Updated the maximum length of the XML schema Destination Host element to 255.
  

• 
  Fixed a server deadlock that could occur when launching a client that had 100,000 or more tags configured for a device.
  

• 
  This initial release of the serial driver provides connectivity to IEC 60870-5-101 slave devices in electrical substations that include RTUs, IEDs, controllers, and gateways.

• 
  Removed “SCL” from titles and labels in the UI where the terminology was confusing, and replaced it with the file types the driver can import (*.cid, *.icd, or *.scd).
  
• 
  Fixed an issue where a failure during automatic tag generation caused previously automatically-generated existing tags to be deleted.
  
• 
  The configuration now allows the automatic tag generation of tags imported from Edition 2 *.icd files.
  

• 
  Added the new CEG model and made protocol changes to slave mode to support a maximum of 500 register and 8000 coil tag reads.
  
• 
  The driver will now attempt a retry on receipt of a send socket error. Prior to this change, certain devices could respond with a socket error after the initial connection and cause an unnecessary disruption in communication with that device.
  
• 
  Fixed an issue introduced in TOP Server Version 5.14 where tags on one or more devices may stop being serviced if another device under a channel has been deleted.
  

• 
  Increased the maximum number of channels from 100 to 256.
  
• 
  Updated the driver so that it will not force the access of tags added manually to be Read Only when the Set write access for imported database tags option is unchecked. This option only applies during automatic tag generation.
  
• 
  Updated automatic tag generation to force the internal tags that should be Read Only to be Read Only.
  

• 
  Fixed an issue where the driver was not working correctly when unexpected characters were received from a non-Omron device that supported the Host Link protocol.
  

• 
  Fixed issues with reading and writing UTF-8 characters that exceeded the tag-defined length limit in bytes. Truncating the strings resulted in the strings being invalid. Strings are now truncated appropriately.
  
• 
  Fixed an issue where device reads may be starved for a device under a channel if another device under the same channel is not in an error state. This prevented the device in an error state from coming out of the error state.
  
• 
  Added automatic tag generation support for Date_And_Time variables.
  
• 
  Updated the driver to use the configured Request Timeout while processing remote CPU Forward Close requests to expedite tag failures during communication timeouts.
  
• 
  Added read and write support for the DateAndTime variable type.
  
• 
  Fixed an issue where an address ending with a UTF-16 surrogate pair resulted in a Variable Address with the length field set to zero.
  
• 
  Added support for reading and writing Unicode characters to STRING Controller Variables. The foreign languages supported include but are not limited to Chinese, Japanese, Korean, German, Russian, and Spanish.
  

• 
  Enhanced the OPC DA Client Driver so that it will now attempt to re-add failed items.
  

• 
  Changed the driver to pass through source timestamp to tags instead of server timestamp. The timestamp will not be updated if the source timestamp is not provided.
  

• 
  Updated the Tag Editor in the Transaction Editor to enforce the rules for tag names; specifically, to not allow trailing whitespace. This solves issues where copying and pasting a name that contains whitespace at the end caused the tag to fail validation. The Tag Group and Tag Block Name dialogs were also updated to enforce this.
