4.23.1 12-11-2013 Corrections:
1- AGC 212/AGC 222/AGC 232/AGC 242 front foil: LED on the right side of the load arrow is now indicating voltage OK on busbar. In special Application configurations (Single DG
Application drawings with Mains present, except if the Genset mode, Ch 6070, is in Island Operation) it is indicating Mains OK/NOT OK.
2- "Live voltage detected" alarm in emulation mode will now occur, if voltage is detected on the AC measurement terminals.

4.23.0 28-10-2013 New features:
1- Identifier texts able to handle Uni-code strings.
2- AGC 245 and AGC 246: Menu 7005 extended with a separate selection of 3-phase CT mains power measurement. No backward compatibility is compromised due to this update.

Corrections:
1- AGC 245 and AGC 246: Mains power via 4th current input now calculated together with voltage on connector 61 instead of connector 68.
2- Log system extended so Event log, Alarm log and battery log are handling 150 entries.
3- Access lock updated: While Access lock is activated all the parameters and service information is able to be read.
4- Configuration of output relays corrected, so all functions can be connected to all available relays.
5- Selection of multi inputs for fuel pump logic corrected.
6- External IO: Analogue input scaling and unit are configured correct at startup and when changing the engineering unit.
7-Start sequence was interrupted almost immediately in emulation mode when doing CBE sequences. The reason was that nominal rpm was obtained instantly.

4.22.1 23-08-2013 1- Application emulation with breaker and engine commands inactive couldn't start the emulated genset properly.
2- DG not being under PMS control was still contributing to power summations used as basis for power reference calculations. PM backward compatibility is compromised due to this update in respect of taking DGs out of PMS control.
3- Endless start attempts when using CBE and rpm thresholds set to 0 rpm.
4- When synchronising BTB to external/unknown voltage source, the DGs online would not always react according to synchronisation command sent from the BTB. No PM backward compatibility is compromised due to this update.
5- M-Logic command "Start and Close GB" was ignored during cool down.
6- Idle run could elapse more than once during start sequence.
7- Command timer now able to activate even though unit is powered up in the middle of the period.
8- Application configuration for AGC 245 now drawn without the tie breaker as default.
9- Pushing hidden buttons results in event log entries.
10-Error in configuration of a parameter was causing the configured parameter to be hidden from the DEIF utility software parameter list. Error introduced in version 4.22.0, now removed.
11-"Mains sync. inhibit" accuracy on frequency threshold improved.

4.22.0 14-06-2013 Changes:
1- Ground relay: Update of the way the ground relay is activated; prioritising is now the power management priority number instead of the CAN ID.

Corrections:
1- Calibration of supply voltage measurement in production corrected.
2- PT sensor offset parameters now corrected to compensate for the cable resistance.
3- Power Management manual priority rearrange bug in the setup menu corrected.

4.21.0 31-05-2013 New features:
1- Option "Emulation" introduced.

2- Functionality for limiting amount of nominal power allowed on busbar at a time due to limitations of short circuit current expanded to be included in the system logics of the DG and Mains. Until now it has only been supported by BTB units to determine whether connecting to sections was allowed. No PM backward compatibility is compromised due to this update.

3- Possibility of closing all BTB's in a ring-bus application added. No PM backward compatibility is compromised due to this update.

4- TB synchronisation will now be initiated in case the multi start forces start of too few DG(s) to get sufficient available power on busbar to meet the power reference. No PM backward compatibility is compromised due to this update.

5- 4 different voltage/power scalings introduced covering range from 10V/1.0kW up to 160kV/900.0MW. It is possible to have controllers using different scaling within a power management application. Controllers having PM compatibility version 1.00.0 or newer are able to understand if other controllers are using scaling even though they are unable to perform scaling themselves.

6- Separate settings for nominal busbar voltage introduced enabling synchronisation over step up/down transformers.

7- Menu 7054 in Mains unit for enabling common cos phi reference to DG(s) expanded. Possibility of making cos phi reference for DG(s) load dependent to hold fixed cos phi across MB added:
a. Off (DG, Mains).
b. Fixed for DG(s) (Mains).
c. Fixed for imp/exp (Mains).
d. Superior (DG).
No PM backward compatibility is compromised.
In fact DG(s) with older PM compatibility versions will be able to handle it if “Fixed for imp/exp” is selected in the Mains unit. “Superior” is the setting used for taking in cos phi reference from a unit placed at higher level in the system. If for instance DG(s) are to take in reference from a Mains unit, “Superior” must be selected in the DG(s).
If DG(s) are to use their local reference the setting must be set to “Off”.
In case “Fixed for imp/exp” is selected in a Mains unit it will seek to compensate for any DG(s) not being in “Superior” to maintain the requested cos phi across its MB. DG(s) with older PM compatibility version will behave as if “Superior” was selected and will therefore only use local reference in case no reference is received from the mains unit.

8- Load profiled running hour counter added.
This counter is weighted with the percentage load of the DG.
This counter is selectable as type of running hour on which to base DG priority in menu 8113:
a. Total.
b. Trip.
c. Load profiled.
Load profiled selection will not be compatible with units having older PM compatibility versions.

9- Priority handling updated.
Now it is possible to make manual update of priorities in menu 8086 depending on either user defined priority order or according to running hours.
a. Off.
b. Manual update.
c. Running hour update.
This is independent of priority routine selected of the type selected in menu 8113.
No PM backward compatibility is compromised due to this update.

10-Possibility of subtracting DG(s) from Power Management system added. It is now possible to select a Genset mode in menu 6071 other than “Power management” when being part of a Power Management application. When doing so normal operation of a SingleDG will be obtained.
The DG(s) will no longer be available to the Power Management system.
The Power Management communication itself will remain intact and no alarms will be introduced in the system.
No PM backward compatibility is compromised due to this update.

11-Test in Island mode supported.
Selecting TEST mode in a Mains unit being in Island mode will now result in execution of a test sequence.
This is only true as long as either “Simple test” or “Full test” is selected as test type in menu 7044.
If test type is set to “Load test” the TEST selection will be ignored.
Units containing lower PM compatibility version will not be able to meet such Test request from the Mains unit.

12- Imax demand and Ithermal demand detection implemented.

13- Pulse counters implemented.

14- Oil renewal functionality implemented.

15- Additional analogue gov/avr offsets added. Now a unique set of offsets exists for each set of nominal parameters.

16- Derate function updated to support monitoring of three different input measurements instead of only one.

17- Additional energy counters added. Now separate set of counters exist for active and reactive energy both for export as well as import are available.

18- Command timers made accessible via display and made more start/stop dedicated. Backward compatibility is compromised.

19- M-Logic entries added for jumping to certain display views.

20- "Woodward SPM-D11" added as possible type of load-share units to interface to.

21- Support of Ground breaker feedback handling. No PM backward compatibility is compromised due to this update.

23- View line informing about active regulators added.

24- Delta Analogue alarms 1-6 added.

25- Mains sync. inhibit functionality added.

26- Average U busbar high alarms added (menu 7480 + 7490).

27- M-Logic flag for acknowledgement of all AC mains protection alarms added.

28- Parameter modified support added.

29- Controller redundancy support added.

30- Breaker, engine and mains transformer names made part of identifiers.

31- Additional engine values supported in MDEC protocol.

32- RPM from engine communication can now be used in CBE sequence.

33- TB deload request added in M-Logic in SEMI-AUTO mode. In addition the 4th current input can be used for TB power. No PM backward compatibility is compromised due to this update.

34- Frequency and voltage droop regulation for DG implemented. Activated in M-Logic.

35- Read out of active fail classes on modbus address 1057.

36- Various existing functions added to use in or activate via M-Logic.

37- Ext analogue f/P reference and U/Q reference available via multi inputs. Configuration done via M-Logic.

38- Gov/AVR 5sec pulse from M-Logic now configurable in pulse length.

39- Force to CanShare from PMS functionality implemented (like analogue to PMS).

40- CanShare communication failure alarm implemented in menu 7860.

Changes:
1- Heavy consumer functionality optimised. PM backward compatibility is compromised in respect to heavy consumer handling.

2- U and Q low (1960 + 1970) alarms extended with two parameters (minimum current and phase angle) before the alarm can be activated when the voltage goes below the set point.

3- Various checks for BTB initialising close sequence bypassed in case BTB is configured as normally open and in Auto mode.
No PM backward compatibility is compromised due to this update.

Corrections:
1- A normally closed Vac BTB being in AUTO and ready to close, but unable to do so due to missing BA and BB voltage, could block for other BTBs in the system to perform automatic closing.
No backward compatibility is compromised due to this update.

2- Incorrect voltage reference would be used by DG(s) when synchronising a BTB against Mains connection(s). Phenomenon occurred when BTB was synchronising with DG(s) connected to busbar on one side and only Main(s) connected to the other.
No backward compatibility is compromised due to this update.

3- Last 2 open BTB's in a ringbus application could both initiate synchronisation at the same time in SEMI auto and consequently close at the same time even though closed ring not allowed.
No PM backward compatibility is compromised due to this update.

4- GB(s) could trip unexpected in applications with Mains without TB. Phenomenon could occur in case MB was performing back synchronisation and expirienced a MB close failure.
No PM backward compatibility is compromised due to this update.

5- If doing LTO without sync to mains or AMF with "Start engine" MB would trip when DG volt/freq okay though the DG was performing initial Idle sequence. Not MB waits until DG is ready.

6- Correction to Idle sequence when Idle stop not used.

3.68.0 24-05-2013 Changes:
1- Ground relay: Update of the way the ground relay is activated; prioritising is now the power management priority number instead of the CAN ID.

Corrections:
1- Stop of DG during idle run secured even if idle stop is not enabled.
2- Idle speed could cause blackout in LTO and AMF when the DG starts. MB remains closed until DG is ready to take load (only when 7065 is configured to "Start engine").
3- GB(s) could trip unexpectedly in applications with Mains without TB. Phenomenon could occur in case MB was performing back synchronisation and experienced an MB close failure. No PM backward compatibility is compromised due to this update.
5- PT sensor offset parameters now corrected to compensate for the cable resistance.
6- Power management CAN B line disabled when switching from Standard application to Single DG application.

Changes:
1- Changing language can be done without reboot/power cycling the AGC.
2- Ground Relay handling updated: Ground Relay activates as DG start up and remains activated until GB closed. Ground relay will open again in case GB closed and larger DG being on busbar and not preparing to disconnect the active Ground Relay. PM compatibility compromised in respect to GroundRelay functionality.
3- DG able to abort on-going stop sequence as long as extended stop sequence not yet initiated.


Corrections:
1- Modbus communication via TCP/IP is now allowed with slave id's in the range 1-255.
2- U and low (1960 + 1970) alarms reaction time enhanced (faster reaction) when alarm state is caused by phase value and voltage already below set point.
3- Relay regulation now working correct with small differences (0,1Hz and 0,2Hz) between dfMax (ch 2021) and dfMin (ch 2022) for dynamic sync.
4- Textual clean up in protection menus.
5- If "DG missing" alarm was present as well as G3 option the unit would switch to analogue var-sharing. This is "old style" handling.
Long time ago it was added as Mlogic entry to control when to force the use of analogue load-share. However it seems as the implementation at that time only updated this for kW-sharing.
6- Voltage level for analogue load-share where reset to 4.0V at every power up when "CumminsPCC" was selected.
3.63.0 09-02-2012 New features:

Changes:
1- Changing language can be done without reboot/power cycling the AGC.
2- Ground Relay handling updated: Ground Relay activates as DG start up and remains activated until GB closed. Ground relay will open again in case GB closed and larger DG being on busbar and not preparing to disconnect the active Ground Relay. PM compatibility compromised in respect to GroundRelay functionality.

2- Missing parameters in ASW and USW added: 1340 BB Voltage Trip, 1390 BB freq Low 2 alarm and 1500 Unbalance Current alarm.

3.61.0 24-06-2011 New features:
1- Support Cummins PCC analogue loadsharing added via IOM 220/230.

Changes:
1- Menus (7000+7010) for power measurements on mains with external transducer available in AGC 212, AGC 213 and AGC 222.

Corrections:
1- Read out of ADEC value Mean Trip Fuel Consumption corrected, Coolant temperature, Fuel temperature and Charge air temperature now displayed with one decimal as for ADEC/MDEC for all J1939 protocols.
2- Termination of analogue load share Island Ramp in case of frequency increase.

3.60.0 06-06-2011 New features:
1- Support of Connectivity check of external connections (RS485 or TCP/IP).
Used to verify if the external communications connected in a network is actually online or not (USW\SuperVision).
2- Support of Power Management Compatibility check.
Used to verify if the power management functions are compatible between SW variants (USW\SuperVision).
3- Support of Genset Data display to be displayed in the USW\SuperVision.
a. Compromises compatibility of Running Hour information amongst the controllers.
4- Preparation for scaling support to be introduced in upcoming AGC-4.
Power management system now able to handle Step up/down transformers on busbar.
a. MB, TB and BTB synchronization compromised.
b. Power capacity check compromised.
c. LD start/stop in apparent power compromised.
5- New Fail class "Trip MB/GB" added.
6- Normally energized alarm relay handling supported.
7- Normally de-energized breaker relay for MB continuous breaker handling added.
8- Possibility of obtaining infinite synchronization during static synchronization without giving breaker close commands added.
9- Power references possible to read out in views.
10- Power factor reference possible to read out in views.
11- Cosines Phi read out supported.
12- Power factor read out now reads out true power factor.
13- Low speed alarm added.
14- Aus mode supported in Mains and BTB units.

Changes:
1- Phase sequence error detection updated. Now the phase sequence error check is always performed on both side. The phase sequence detected is
compared with the user defined expected/intended phase sequence.
2- BTB will wait for a period of time, equal to LD stop delay, before initiating its deload sequence during active operation.
3- MB is now able to perform black closing even though it is missing all units on the CAN line as long as TB is present and open.
4- Extended Stop is now executed whenever a Semi Stop command is given when the DG is at halt. This is despite the mode of the controller.
5- In Power Management application where “Update All” is selected, a controller being in Block mode will listen for the last mode update made
in the system and return to that mode when leaving Block mode.
6- Service timer alarm now activates at 08.00 in the morning instead of 00.00 at night.

Corrections:
1- If TB was in the process of synchronising in Semi Auto mode, the sequence could not be aborted by a TB open command given via modbus.
2- If MB opens (trips) during LTO sequence before TB is synchronized and “SyncToMains” is enabled the TB do not connect DG(s) to load
as system expects synchronization to occur.
3- LTO sequence is active on IDToRun. Another Mains has MCU status and mode is shifted from SEMI to AUTO or vice versa on that Mains unit.
The LTO sequence is shortly interrupted – if BackSync ON MB is synchronized for ½s and then cancelled,
if BackSync OFF then TB is tripped (causing blackout) and MB closed and TB re-synchronized.
4- If common load present right of BTB and the Right Island was called upon from the left side,
the BTB would close before a DG managed to connect on the right side. If the other way around the BTB would wait until
DG connected to the left and then synchronize and close.
5- If LD start/stop was done in percentage instead of in absolute value, the calculation to determine whether swapping of DGs due to priority order
should be executed was invalid. The calculation secures that the swapping only takes place if the DG to be substituted is able to be stopped on
LD stop condition after connecting the substituting DG.
6- A DG start threshold functionality already exists. It provides the possibility of adding a threshold value that a user defined input must
exceed before start sequence is initiated. The implantation was done in a way so the threshold value should be exceeded whereas just being
equal to was not sufficient. This gave complications if the threshold was to be done with just a digital input. Due to the general improvement
of scaling handling this is now possible. As the digital input of the value “1” is compared to a one decimal threshold value any threshold
value between 0.0 and 0.9 will now be seen as being below the value of the digital input.
7- NEL relays did not activate when application type was of the type "SingleDG".
8- If both ON and OFF feedback high on TB the MB would close without synchronization to voltage on busbar.
9- Control registers for enabling/disabling external control via constant commands instead of toggle commands added.
10- Transmit rate of speed telegrams (FF46 and TSC1) to EMS2 increased from 40ms to 20ms.
11- MMI updates regarding translate able texts and more space for alarm numbering in alarm list.
3.54.1 04-03-2011 1- AGC 222 supported.
2- Parameter 1560 “Neg. seq select” made independent of parameter 1590 “Zero seq select”.
3- Option H2 Modbus improved in multi drop configurations.
4. In BTB units was some fail classes not shown correct in USW and display.
(Ch 1540, 1550, 1560, 1570, 1580, 1590, 1600, 1610, 1660 and 1700)”
5. RMS measurement improved. Before RMS measurement could be little outside Class 1 at a few frequencies. Measurement was all the time within Class 1 at 50 and 60 Hz.

3- MMI: IP address is now displayed without extra ‘0’s.

Corrections:
1- PF was wrong if (P + Q) > 65535.
2- Df/dt calculation (Option A1) is updated for correct detection . Only relevant when number of measuring periods in parameter 1422 is set above 4.
3- MMI: Time Dependent Low Voltage Menu 1630+1640. Timer set point calculation for decimal resolution and setup of unit corrected.
4- MMI: Unit corrected to kV, if measure value is above 9999V.
5- MMI: Number of decimals corrected, when power factor is capacitive.
6- MMI: The first item in gateway address readout was IP address – now gateway address is shown.
