• Improved parameter look-up speed, reducing time required for configuration and troubleshooting.

• Hardware: Support for T option card (1 x mA output - 4 x mA input).
• Function: DIF (Idx>) [87T] and GMAG: Individual setting groups (SGS2). 
• Generator module: Nominal scaling manual mode. 
• VRG1 (Vreg) [90]: Parallel Voltage Regulator.
• GMAG: Excitation current to mA Out channel selection. 
• HMI: Alarm view colour selector. 
• HMI: Arabic language to start screen. 
• HMI: Chinese font support for objects. 
• Communication: Ethernet GOOSE storm protection parameter. 
• Communication: Double Ethernet PRP ports parameter.
• Communication: Support for PTP power profiles and VLAN-tagged frames. 
• Communication: Scaled analogue inputs to IEC 104. 
• Communication: CTS2 to IEC 61850 mapping. 
• Communication: URX1 and URX2 [21X] conditions to IEC 61850. 
• Communication: VHZ1 (2) conditions to IEC 61850. 
• Communication: Capacitor Protection Module Conditions COL1/2 and CNU1 to legacy protocols. 
• Communication: U3/U4 frequency to IEC 61850. 
• Communication: Switch positions added to GOOSE.
• Communication: GOOSE analogue values added to HMI and programmable stages.

Changes

• Pole Slip [78]: Function improvements.
• Synchro check [25]: Added LL/DL/LD/DD mode, ability to select line or bus as reference, additional signals. 
• HMI: Default mimic updated to light theme. 
• HMI: Several menu item and text adjustments, addition of function ANSI codes. 
• Fault register: "Fault values register" and "Measurement value recorder" renamed to “Fault register”.

Corrections

• Synchro check [25]: SYN2 and SYN3 force status. 
• Current transformer supervision: Current transformer supervision functionality was not working if delay was not zero.

• Frequency measurement: Min/Max tracking frequency allowed limits were not working. 
• Frequent start FSP (N>) [66]: Frequent start stage was not working correctly.
• Logic: >= comparator was also activated on negative values. 
• Objects: Default user level changed from operator to configurator. 
• HMI: Push buttons were in undefined state after reboot if set to toggle mode. 
• HMI: Reset to factory defaults will now reboot HMI and clear mimics and fault registers correctly. 
• HMI: Custom event description display on event list. 
• HMI: Vector and trip time characteristics.
• HMI: Measurement bar scaling.
