HMI Improvement to P3SXSWI function "Reed not closed" command response to LHMI.
Communication
Improved robustness on functionality when disconnecting IEC 60870-5-104 communication.
Improving communication error handling in case of SFP transceiver is unplugged while Line Differential communication is in use.
Redundant Ethernet channel supervision RCHLCCH ,HSR/PRP diagnostics improvement. Removing unnecessary CHLIV TRUE/FALSE events when no other devices connected to network.
Improvement to the Frequency measurement FMMXU avoids unnecessary reporting during momentary vector shift situations.
Scaling issue fixed with SIM1001 card when Sending/Receiving Calculated Io value via SMV (IEC 61850-9-2 LE).
Improvement on GOOSE receiving. In a system where one relay is receiving GOOSE communication from multiple senders, it is possible that a communication break in one sender might impact handling of received values from other senders.
Improvement to IEEE 1588 PTPv2 Time synchronization Timesource field indications fixed. Before relay announced PTPv2 TimeSource=GPS if the relay was previously synced to a GNSS/GPS grandmaster, even GPS connection was lost. Now the REX640 ordinary clock was modified to announce TimeSource=Internal Oscillator regardless of previous state.
Enhancements to IEEE 1588 PTPv2 Time synchronization to expedite master negotiation process.
Engineering
Handling of erroneous SMV SCL communication configuration improved. Prior, the relay might become unresponsive if an erroneous SMV configuration was written to the relay.
Supervision
User Account Management (UAM) enhancements. - Updates to default user Roles and rights.
Note: Activating updated default role changes requires relay factory restore or restoring the user accounts from PCM600 after update, and then custom roles and rights can be written again (Customer configuration) to relay.
- Preventing firmware updates with operator credentials from PCM600 Firmware Update Tool.
