Fixed an issue where reads would fail on a dynamically addressed array when the datatype was not specified. Enhanced driver to support new CIP data types found in firmware Fixed an issue where adding a dynamic Boolean tag with an unsupported data type would appear to add a valid tag. Added Japanese language support. Updated the driver to correctly handle UDTs as referenced in firmware Added support for L8 Series controllers.
Resolved an issue where a dynamic array tag could be orphaned due to an abrupt disconnection of the client. On reconnect, the array tag was unable to be re-added by the client.
Resolved issue that prevented reading arrays with more than elements when using the Logical Blocking protocol mode. Fixed an issue where the first read from a device that had been in an error state returned bad quality. The read now returns good quality if the device is available Fixed an issue where the thread count increased when changing the device ID via a System Tag.
Updated the driver to work with future-generation devices and firmware. Before this fix, the driver experienced a communications failure with these devices. Increased the maximum channel limit from to Fixed an issue where automatic tag generation from an L5K file failed if the L5K contained an AOI parameter that aliased another parameter. AOI alias parameters are not supported in automatic tag generation and should not be automatically generated.
This would prevented 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 or more characters. This does not require clients to specify the data type upfront. Fixed an issue where Boolean array writes were not supported in Logical Mode. This was a rare occurrence that had to do with improper event handling. Fixed an issue where reading arrays of 64 bit data types LINTs that spanned multiple transactions would fail.
Fixed an issue where switching from Symbolic Mode to any Logical Protocol Mode without reinitializing the server would not honor the Logical Mode and would stay in Symbolic Mode.
The supported range is now to where it had previously been hard set to Corrected the message size estimation for Symbolic Writes, which was making it possible to underestimate and overflow a request packet. Changed a behavior where the driver will now retry tags instead of failing them upon detecting an Online or Offline edit except for Downloads.
Also, Offline edits will take priority over Online edits if both occur before being detected by the driver. Fixed an issue where the Protocol Mode drop-down selection arrow would not redraw correctly if the selection invoked a vertical scroll bar in the grid. This caused the driver to revert to and stay in Symbolic Mode.
Added project change detection support for online and offline project edits. Device setting, "Synchronize with Controller after", is available on the Logix Options property page. This time period has been lowered from 60 seconds to 30 seconds to improve recovery time. In the event of an "Invalid or corrupt project" error during synchronization, we now wait 30 seconds until retrying again.
Before we retried immediately which caused unnecessary upload attempts and event log errors. Added support for failing a synchronization in progress as soon as a project download is detected. Synchronization will be retried after 30 seconds.
Fixed issue that was causing an unnecessary event log message to be posted if a project change occurs during a CIP reconnect Idle Watchdog expires. Improved logic that determines how many reads or writes can fit in a single packet, yielding a slight increase in performance. Message size estimation for Symbol Instance reads was incorrect for array element blocks whose starting offset exceeded likely , making it possible to underestimate and overflow a request packet.
Message size estimation and generation for Symbol Instance writes was incorrect for paths exceeding in size unlikely. Improved the demotion of tags while in an error state by increasing the number of tags failed per transaction. The driver still attempts at least one read tag per transaction to recover from the error state. This does not apply when Auto Demotion is enabled. Fixed an issue where project correlation state information was not being properly reset when switching from one device connection to another which could result in that device using Symbolic mode indefinitely.
Resolved a buffer overrun issue where the Device ID could become corrupt if the length of the portion preceding the comma exceeded 16 characters. If it exceeds a single packet, the tag will fail with "Address out of range".
For example, the Float With this fix, Fixed an issue where the driver could report incorrect data to client applications if the value read was greater than , bytes such as in an array of DINTs. This only occurred on devices configured for Physical Blocking Mode. Updates for RSLogix version Performance statistics are now properly disabled when non-ControlLogix models are selected. Added a check for a delete pending on each tag before the tag is issued for device communication.
Fixed a write issue with LBCD arrays where the driver was writing to every fourth Dword instead of every fourth byte. Fixed discrepancies between L5K and L5X import. Resolved an issue where the driver was not correctly handling the connection routing path to a remote device which could cause the driver to fail Automatic Tag Generation and report an invalid device ID. Limited Serial Gateway node id to DF1 limit of When unchecked, string reads will be optimized by having the driver bypass the LEN member read and terminate the DATA string at either the first null character encountered or the maximum string length of DATA whichever occurs first.
Beginning with L7x controllers, an optimization in controller memory restricts that memory cannot be accessed on a non-DWord boundary or a controller fault will occur. Because the driver was not aware of this restriction, it was possible it could fault the controller while performing Physical reads or writes. To address this issue, the driver now identifies the controller and makes the proper Physical memory access.
Resolved an issue with Auto Tag Generation that occurred if a project correlation error was detected. Increased the maximum number of Programs supported from to Fixed application exception that can occur when multiple Logix Array elements are added and removed at random, followed up by a project upload due to inactivity, change in project, etc. Fixed various anomalies where tags could not be auto generated via L5K. Added support for automatic tag database generation using.
L5X files. Added support for asynchronous hostname resolution. This only happened for projects with multiple channels. A driver is a software component that enables KEPServerEX to meet the connectivity requirements of a specific device, system, or other data source.
The driver handles all proprietary communications to the data source for KEPServerEX; the client interfaces handle all supported OPC, proprietary, and open standards connectivity to applications that monitor or control the devices. Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve.
