TOP Server Version 4.180.338 Released - (Download here) (More Information on Drivers)

• New Driver Suites
• Siemens S5/S7 Suite - combines S7-200/300/400 Ethernet, S7 Unsolicited Ethernet, S5 AS511/PG port serial, S5 3964/3964R, and S7-200 PPI drivers into a single orderable item
• Mitsubishi Suite - combines Mitsubishi A and Q series serial and ethernet drivers with FX Serial and FX-Net serial drivers into a single orderable item.
• Simatic/TI Suite - combines Siemens/TI 5x5 series NITP/TBP serial driver with Siemens/TI 5x5 series ethernet driver into a single orderable item.
   
• ServerMain.exe Updates (V4.180.338)
  -Enhancements:
• Added the following application system tags: Date_Month, Date_Day, Date_Year4, Date_Year2, Time_Hour, Time_Hour24, Time_Minute, Time_Second, Time_PM.  These tags break up the components of the existing Date and Time system string tags, so that client applications are no longer required to parse the strings to obtain the individual elements.
• Last file Open and Save As paths are now shared rather than being separate.  This makes it easier for users to Open up the last saved project if it resides in a location that is different from the last opened project location.
• Added multi-line tool tip support for the event view.  If the column that the mouse cursor is over contains text that can not be fully displayed in the current view, a tool tip with all the data will be shown.
• Upon loading the server that utilizes a driver that has had its license expire, we will now periodically log an event message to indicate that the license has expired when a client attempts to add items that references.
• Updated event log Copy/Paste contents to include the date and time with each TX/RX frame in the same format as the event log and OPC diagnostics.  This will assist with cross-referencing diagnostic information.
• Increased the number of drivers that are displayed when selecting the driver name drop-down list in the 'New Channel - Device Driver' channel wizard page.
• Added event log message when the enabled state is modified on a device.  On startup, a message for each device that is disabled is logged to indicate the disabled state.
• Fixes
• Fixed issue with not being able to undo changes made on a channel (e.g., Name).
• Fixed alias dialog issue where the where the keyboard focus would be lost after deleting an alias (i.e., unable to use the tab control to move to other controls on the dialog).
• Fixed alias mapping issue where the Map To string would always concatenate the newly selected path to the previously selected path.
• Fixed DA 3.0 compliancy issue when running on systems with multiple processors or hyper-threading enabled. Cloning a group with a requested interface that is not supported by the group, could cause the server to not perform device reads on any item that referenced the same address (qualified ID) as an item belonging to the cloned group. The result is that the server would always return failure for a device read request on these particular items for the lifetime of the client/server connection that performed the Clone Group request.
• Fixed DA 3.0 compliancy issue when running the server on a machine with multiple processors or hyper-threading enabled.  Due to the nature of the fix and how it would affect existing projects the user must enable this compliance fix under Tools | Options | OPC Compliance : "Return initial updates for items in a single callback".  When selected (compliant behavior) we will return all outstanding initial item updates in a single callback.  When deselected (default behavior) we will return initial updates as they are available which could result in multiple callbacks.  Note: If the server was previously running with Full Compliancy selected, this will automatically be deselected so that the pre-existing behavior is maintained.
• Fixed potential application deadlock when viewing Channel Diagnostics and either Resetting or Pausing the view.
• Fixed unnecessary event log from being posted if you enable auto demotion and disable auto demotion, while not in a demoted state.  The server would log a message indicating the device was auto-promoted even though it was not demoted.
• Fixed event view painting issue when sorting the event list by Date/Time when Autoscroll was not selected.
• Intellution PDB Interface - Fixed issue that would cause integer data to sometimes be displayed in floating point format when using TX blocks.

Drivers

• AB Ethernet:
  -Upon failing after x successive timeouts, the driver will close the communications socket to reduce the possibility of having to synchronize with previously buffered requests.
• AutomationDirect EBC:
  -NetEdit launch has been moved to General tab on Device Properties dialog.
• AutomationDirect ECOM:
  -NetEdit launch has been moved to General tab on Device Properties dialog.

• Allen-Bradley DH+:
  -Fixed ASCII (A File) issue where the last element of an array would always read NULL for arrays of even length size starting at an odd byte offset.
• Allen-Bradley Ethernet:
  -Fixed ASCII (A File) issue where the last element of an array would always read NULL for arrays of even length size starting at an odd byte offset
• ControlLogix:
  -Renamed model "ControlLogix 5550" to "ControlLogix 5500" to better represent the 5500 series of supported ControlLogix CPUs.  Previous and current support under this model include: 5550, 5553, 5555, 5561, 5562 and 5563.
  -Fixed Physical Blocking read issue for UDT's greater than 65535 bytes in size.
  -Fixed issue that could cause an unnecessary "CIP connection timeout" when going from Symbolic Addressing Mode to a Physical Addressing Mode.
  -Average Device Turn-Around Time (ms) to Performance Statistics.  This will aid in gauging how long it takes on average for the PLC to respond to the request.
  -Fixed bug that could cause unnecessary "CIP connection timeouts" during auto tag generation and/or project upload.
  -Added support for ENI:Micrologix Function Files: RTC, HSC, IOS, CS0 and CS1.
  -Fixed ASCII (A File) issue where the last element of an array would always read NULL for arrays of even length size starting at an odd byte offset
• DF1:
  -Fixed issue where a write of LEN bytes to an ASCII (A File) string of length LEN would write two NULL terminators to the bytes following the string.
  -Added SLC 5/05 to Model selection.
  -Fixed Half-Duplex Master issue that would halt writes to a Slave if a previous Master Message write request was never received by the Slave.
  Fixed ASCII (A File) issue where the last element of an array would always read NULL for arrays of even length size starting at an odd byte offset

  -Added unsolicited support for the following 3 data encoding options: Modbus byte order, First word low in 32 bit data types and First Dword low in 64 bit data types.
  -Fixed issue where the "First Dword low in 64-bit data types" checkbox was not honored when reading/writing to tags of type double.
  -Added support for multiple slave devices.
  -Wonderware users who need to make Tag databases changes in Excel should contact us about a new feature that can handle Output registers without the leading zero.

  -Fixed issue where writing to a string that overlaps another string(s) nearby caused junk characters to appear in the overlapping string.
• Modbus Serial:
  -Device Id range modified to allow 248 to 254
• Modbus Plus:
  -Wonderware users who need to make Tag databases changes in Excel should contact us about a new feature that can handle Output registers without the leading zero.

• Omron Fins Ethernet:
  -Fixed E registers read issue for the CJ1 model devices.  This issue was discovered during Omron Toolbus testing which was inherited from the Omron suite.
• Omron Fins Serial:
  -Fixed E registers read issue for the CJ1 model devices.  This issue was discovered during Omron Toolbus testing which was inherited from the Omron suite.
• Optilogic:
  -Added delay between reading the base definition and performing reads/writes to allow the base to complete the initialization sequence on power-cycles and cable reconnects. The delay prevents the possibility of the base locking up.
  -Tags are no longer deactivated if an address is out of range or specified slot doesn't exist.  Therefore, if they ever become available the user will not have to restart the driver/server to obtain the data.
• Siemens S7-200:
  -Added transaction id to read/write frames to facilitate packet synchronization over noisy networks resulting in duplicated/resent packets.
• Siemens MPI:
  -Added Array Support for Byte, Char, Word, Short, DWORD, Long, Float and LBCD data types.
