GE tracking number: 581-4
P
The “Non-Volatile Latches” elements have been changed to ensure they will maintain the output
status when cycling power to the relay
Products: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.81
Description: Changes to the Non-volatile Latches ensure that those elements maintain the output status
(on or off) when the relay is powered off and on. Previous firmware versions can allow the elements’
output to momentarily change state when the relay power cycles. Customers using the “non-Volatile
Latches” for protection or control purposes are advised to upgrade their relay firmware version.

Changes to the GGIO4 data set prevent ”Data Access Errors” in its unbuffered report control block
Products: B30, B90, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.80
Description: GGIO_4 and GGIO_1 data sets have three report control blocks each. When at least four or
more data items are configured in GGIO_4 and eight or more within GGIO_1, firmware versions 5.71 and
5.80 can allow the GGIO_4 Un-buffered Report Control Block to show the following message “Data Access
Error: type-inconsistent”. The changes implemented to GGIO_4 with this release fix this communication
issue.
