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.
