T9852 PCB BOARD ASSEMBLY Ics Triplex

Description

Overview

Essential details：T9852 PCB BOARD ASSEMBLY Ics Triplex

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
