1. Fixed Bug - Enable and Trigger Group addresses did not update the mapped Comfort Counters
2. Fixed Bug - sending commands to Trigger and Enable groups by Response wizard did not update the mapped Counters
3. Fixed Bug - changing counters in Comfort mapped to Enable group addresses did not send the change to the Enable group. Now this allows commands to be sent to an Enable group by changing the value in the mapped counter

UCM/Cbus2 7.068

1. Sending Flag value mapped to cbus group address will take effect even if the flag state is not changed.
2. Improved firmware upgrade so boot sector may not be updated if there is no change
3. Improved firmware upgrade so it may work even if UCM/Cbus is reset during upgrade
4. If counter change originates from ucm/cbus, comfort broadcast counter change will be ignored by ucm/cbus to avoid the endless feedback and change when slow dimming by cbus2. This improves slider on app

UCM/Cbus2  7.106

1. Fixed occasional problem initial zone state transmitted to C-Bus Security application zone status may not be updated
2. Improved Monitor Mode for cbus soo that messages  Received from Cbus and  Transmitted to Cbus are displayed. Previously, only message from Cbus are displayed. This requires Comfigurator 3.12.2 (not available yet)
3. Work-around for rare problems for some C-Bus networks where the C-Bus serial interface was not able to receive a full status reply for the Lighting Application and hence was not able to initialise resulting in the ERROR led remaining on. Cbus2 firmware will not go into Smart Mode even if the Status Reply is not received from Cbus Lighting application

Fixed a problem when messages are sent from a remote network via a Bridge, that causes the initialisation commands to be sent to Cbus. This causes the lighting status to be requested so that groups which are dimmed (level 1 to 255) cause the mapped counter in Comfort to change to 255.

The bridged cbus command now does not cause a cbus to be reinitialised, instead it is ignored if the cbus mesage is meant for another network

If the cbus is reinitialised due to an unexpected state of the SIM, it will not request the Lighting status again so the problem of counters changing to 255 when the lighting is dimmed will not occur


Known Issues
Enable and Trigger application map to counter does not work

Firmware can be downloaded from https://www.cytech.biz/ucmcbus2_firmware.html

Please note of the bug in the firmware which was recently discovered

Known Bugs

1. Enable and Trigger application map to counter does not work
   
2. When UCM/Cbus2 is reset, the  Status report from the lighting application does not update counters. Only a hard reset ie removing power from ucm/cbus2 will update Comfort counters based on thye Lighting application. The effect of this is minimal, as it can be seen only after Comfort firmware is upgraded when the lighting groups addresses values in the mapped counters will not be correct unless the status of the lighting groups first changes

This firmware upgrade is highly recommended because of the new features and bug fixes below.

Bugs Fixed

1. When sending group address to any application not just lighting,   counter is updated. eg if Trigger group address 1 command is sent to Cbus, Group Address 1 would be updated
   
2. When UCM/Cbus was RESET, only 8 Cbus group addresses were updated to their counters because of a status request
3. UCM/Cbus used to send Daylight Saving Time value of 0 when Daylight Saving time is ON and ignored Daylight Saving Time value from Cbus.
4. Various problems with Cbus Delays which require a Reset of UCM/Cbus to recover
   

New Features

1. Complies with Cbus Clocks and Timekeeping application timing and updating requirements. Responds to Refresh Request Date and Time message from Cbus. UCM/Cbus sends Daylight Saving Time value to Cbus as unknown  and processes DST value from Cbus.
2. Works with older SIM firmware 3 and 4 but not all features may be supported in older SIMs.
3. SIM V3 when Cbus is removed and re-connected can re-initialise after a command is sent to Cbus. Note: Cbus SIM V4 which supports the PUN (Power Up Notification) message recovers by itself when Cbus is reconnected.
4. UCM/CBUS suppports AUD01 plug in
5. UCM/Cbus can receive several messages from Comfort RS485 bus if busy.
6. Read SIM firmware version from SIM for Internnal use
