Rev. Date Editor Changes
◦ Negative energy counters ◦
◦ Active and reactive power setpoints
◦
◦ ISOCH information
◦
• Improved System Interconnectivity by providing advanced CANopen and Modbus •
access on Analog- and LogicsManager variables. ╚═▷ “9.2.9.3 Data Receive
(interconnectivity)”
• Redundant load share Ethernet A and CAN with alarm. indication is possible. •
• The timer setting over the ToolKit screen is improved to make the configuration
•
more comfortable. There are some configuration examples added. ╚═▷ “6.3.17
Examples timer configuration”
Corrections/Repairs
• Breaker transition mode "Closed Transition": Being in island mode with multiple •
running easYgens did not allow constant power control in the single easYgens.
This is fixed now.
• Phase shift (ROCOF) - Not possible to trigger in Decoupling Test Mode. This is fixed •
now.
• The disabling of the maintenance call by configure maintenance hours and days to •
zero is improved. In the past one last maintenance call was executed even the
hours and days were RESET. This is fixed now.
• Improvement Modbus TCP slave handling: Changed receive of Modbus to fix •
occasional blocking of TCP port in multiple Modbus setups.

(VDE-AR-N 4110). See ╚═▷ “4.4.4.2.5 Reactive Power Characteristic” .
• Introduction of a special mains frequency value based on a 200ms gliding average •
value to match an accuracy of 50mHz and better. (VDE-AR-N 4110). See ╚═▷
“9.4.2.2 Group 02: Mains values” .
• The over frequency -active power decrease function is expanded with under •
frequency -active power increase function. (VDE-AR-N 4110). See ╚═▷ “4.4.4.5.5
Active Power – Frequency Function P(f)” .
• Providing a LogicsManager command variable in order to blocking ROCOF Monitor •
during FRT-cases. (VDE-AR-N 4110). See ╚═▷ “9.3.2.7 Group 07: Mains related
alarms” .
• Providing of a configurable hysteresis for mains voltage and frequency monitoring •
(VDE-AR-N 4110) in Rev. J changed again.
• Introduction of a pole-slip monitoring function in parallel to mains operation. (VDE- •
AR-N 4110) ╚═▷ “4.5.1.6.3 Pole Slip Monitoring”
