T9431 digital output card

The following enhancements are included in this release.  Increase Variable Bindings Memory The Variable Bindings (KVB) memory has been increased in size from 64 K to 128 K. This will allow you to increase the number of variable bindings that you can set up between controllers in an application.  New Workbench license for 5 Users, Unlimited Controllers New license option T9084U is available: this is an AADvance Workbench license for 5 Users and no limit to the number of controllers. It is only available as a USB license option: it will work with Windows XP Service Pack 3; Windows Vista; Windows 7 and Server 2003 in both 32-bit and 64-bit versions. The following problems and anomalies have been corrected in this release.  Digital Output Module Shutting Down Under certain operating and environmental conditions noise can be present of one of the digital output module voltage rails. These voltage rails are sampled to ensure that they are within a specific tolerance; but the noise occasionally caused the monitoring circuit to report an over-voltage, resulting in the DO module shutting down. An internal filter has been improved that reduces the effect of the noise and prevents the module from shutting down.

 I/O initialization stalled - TN30051-01 (answer id. 544046) If, during a controller start-up an I/O module failure occurs it can stop the I/O initialization. As a result, the controller start-up process fails to complete, leaving the application program suspended. Changes to the controller start-up have been made that prevents this from occurring.  System power up with a 48 module configuration The maximum number of I/O modules supported by an AADvance controller is 48. Certain configurations, particularly when the majority is Digital Output Modules, can result in a system not starting-up correctly after a power cycle. Changes to the controller start-up have been made to prevent this from occurring.  Processor loss of synchronization In dual processor configurations it was possible under certain conditions for the two processors to lose synchronization, but continue to run asynchronously. Although the I/O still went to its fail-safe mode, it was possible for any binding data to be incorrect. Changes to the controller have been made to prevent this from occurring.  Spurious Soft Error Detection (SED) faults - TN30056-01 (answer id: 564815) Each AADvance module uses one or more FPGA's to provide the communication interface between the processor and the I/O modules. The manufacturer of the FPGA used in AADvance released a Product Notification identifying that this device could spuriously generate SED errors. The FPGA manufacturers recommended changes have been made to the controller to prevent this from occurring.  Processors lost synchronization after an on-line update It is possible that on-line updates to a large system with more than 37 I/O modules installed can cause the processors to lose synchronization. Changes to the controller have been made to prevent this from occurring.  Loss of SNCP Kernel Variable Bindings (KVB) communication Under certain conditions it was possible for both links of dual SNCP bindings configuration to fail. Changes to the controller have been made to prevent this from happening.

 PN2013-09-001- AADvance Controller Consume Network Status Function Block This affected only systems using multiple controllers, SNCP variable data bindings and the KvbConsNetStatus function block. When an on-line update was carried out on the producer controller, the function block stopped working and its outputs remained in the same state prior to the on-line update. This problem affected systems using operating versions up to and including processor build 283. It has been resolved in build 303 onwards.  On-line Updates resulted in unexpected behavior to POUs with names that have leading or trailing spaces - PSA 2013-10-002 (answer id. 568726) Program Organization Units (POUs) that contained leading or trailing spaces in their names can cause variables in those POU's to revert to their configured (or default) initial values instead of current values after the completion of an on-line update. This can result in unexpected logic behavior after an on-line update. POU names include programs, functions and Function Block names. Changes to the Workbench have been made to detect and prevent this from occurring.  Full size Modbus write packets AADvance controllers using modus (TCP or RTU) were unable to write the full 125 word (or 2000 Boolean) data packets. Changes to the controller have been made to prevent this is from occurring.  Workbench out of Memory error Applications programs with a large number of resources (> 16) could cause the PC to run out of memory which resulted in the Workbench hanging. Changes to the Workbench have been made to prevent this from occurring. The following restrictions still apply to this release.  Importing/exporting to/from Excel The Workbench provides the option to export/import to and from Microsoft Excel, this function will only work fully when using Excel 2007 or above. If a user has an older version of Excel they still have the option to export/import to and from CSV files.
