The 3rd generation KNX Interface is called UCM/KNX2 (after UCM/EIB and UCM/KNX)
see webpage http://www.cytech.biz/brochure/comfort-to-knx.html



The main improvements over UCM/KNX2 are;
  1. Improved Mapping of KNX to Comfort objects (see below). Separate mapping for KNX to Comfort registers and Comfort  registers to KNX support KNX objects having different control and feedback addresses.
  2. Comfort Inputs/Zones can be mapped to KNX 1-bit objects so Comfort Input changes (On/Off) can provide feedback for KNX, for example for status of Airconditioners by Current sensor. A different KNX address can be mapped to Output or Counter to control the Airconditioner or appliance. In the UCM/KNX, Zone Responses were needed to send status to KNX.
  3. Comfort Outputs can be mapped to KNX  so that Output On/Off changes can be mapped to KNX 1-bit objects. A different KNX address can be mapped to the same Output. This allows different KNX control group address and Status group address for output control
  4. Flags to KNX allow Comfort Flags to be mapped to KNX 1-bit objects. A different KNX address can be mapped to the same flag in KNX to Comfort. This allows different KNX control group address and Status group address. Flags can be used to control other devices in Comfort which act on the same flag.
  5. Counters to KNX (1-bit) allow Comfort Counters to be mapped to KNX 1-bit objects to send On/off command or status.  Counters to KNX (1-byte) allow Comfort Counters to be mapped to KNX 1-byte objects to send levels.  Different KNX addresses can be mapped to the same Counter in KNX to Comfort. For example, a KNX 1-bit address can be mapped to a Comfort Counter. The same KNX device can send a 1 byte value which is  mapped to the same Comfort Counter as dimming level, as well as map a 4-bit group address to the same counter for relative dimming. The Comfort counter can be mapped to a 1-bit KNX address for on/off feedback as well as to a KNX 1 byte address for absolute dim level.
  6. Sensors to KNX allow Comfort sensors to be mapped to KNX 2-byte Floating Point objects.
  7. With the enhanced mapping of Comfort Registers to KNX, it should not be necessary to use Responses to send commands to KNX, although this is stil possible. This simplfies  programming and saves tim
  8. easier entry of KNX addresses, by just typing the address eg 1/2/3 instead of selecting Main. mid, and subgroup addresses from pulldown lists. Comfigurator will check that the group address is unique
  9. Disarm to Security Off by 1 bit KNX address is possible. This should be applied to specific KNX scenes or situations and not as a general button, for security reasons
Mapping of KNX to Comfort
Mapping of KNX Objects include 1-bit, 4-bit, 1-byte, Time, Date, 2-Byte Floating Point, 2 Byte Counter.



KNX 1-bit (EIS1)
Map to Counters, Flags, Outputs, Output Pulse, Output Toggle, Virtual Input, Arm Security (Security Off,  Away, Night, Day, Vacation), Bypass zone, Panic

  • Mapping to Output means that a KNX 1-bit address turns on and off any Comfort output directly
  • Mapping to Output Toggle  will toggle the output
  • Mapping to Output Pulse sends a 1 second pulse to the output
  • Mapping to Flag allows a 1-bit KNX address to be mapped to a flag so that changing the KNX state causes the flag to change state accordingly. In the reverse direction, Flags to KNX allows flags states to change KNX 1 bit group addresses.
  • Mapping to Virtual Input means the KNX object eg motion sensor can act like a real Input to the security system, according to Zone Types and will trigger the zone Response
  • Mapping to Arm Security allows the KNX object to Arm the security sysyetm to Away, Night, Day, Vacation. Disarm to Security Odd is not allowed, althoughh it is listed in the options
  • Mapping to Bypass zone means the KNX object can bypass and unbypass any Alarm Zone.
  • Mapping to Panic means the KNX Object can trigger a Panic Alarm when pressed

KNX 4-bit (EIS2)
4-bit relative values  can be mapped to Comfort Counters. The counter value is calculated based on the relative change



KNX 1-byte (EIS6)
1-byte Objects (EIS6) can be mapped to Comfort Counters and Keypad Key. Mapping to Keypad Key allows a virtual keypad on a KNX touchscreen to arm or disarm the security system.


KNX 2-byte Floating Point (EIS5)
2-byte Floating Point Objects (EIS5) can be mapped to Comfort Sensors



KNX 2-byte Counters (EIS10)
2 byte Counter Objects (EIS10) are mapped to Comfort Counters.


Mapping of Comfort to KNX
New tabs Alarm to KNX, Inputs to KNX, Outputs to KNX, Flags to KNX, Sensors to KNX, Counters to KNX (1-bit), Counters to KNX (1-byte) allow mapping of Comfort registers to KNX to provide Control and Status feedback to KNX




In Monitor Mode, the meaning of the telegrams from KNX are shown

Upgrading from UCM/KNX

The good news is that UCM/KNX can be upgraded to UCM/KNX2

There are 2 steps;
  1. Upgrade the UCM/KNX to the latest firmware KNX7079. Do this by right clicking on UCM/KNX and selecting Check for Upgrades.
  2. After the firmware upgrade to UCM/KNX 7.079, download the UCM/KNX2 firmware from http://www.cytech.biz/ucmknx2_firmware.html Unzip the knx2 .cbf file into a local folder. In the Modules Tab, right click on UCM/KNX and select Upgrade firmware from Local fileand select the KNX2 cbf file that was downloaded.

Upgrading UCM/KNX

Only UCM/KNX 7.079 and above can be upgraded to UCM/KNX2. UCM/KNX2 firmware can also be reverted to UCM/KNX via the same process.

The UCM/KNX2 7.086 is currently a beta release for testing only

It is also possible to revert to UCM/KNX firmware using the same 2 step method

The UCM/KNX manual can be downloaded fromhttp://www.cytech.biz/knx_interface.html

Main differences between UCM/KNX2 and UCM/KNX



In  UCM/KNX2, 1-bit KNX addresses can  be mapped to Counters, Flags, Sensors, Outputs, Output Pulse, Output Toggle compared to only counters for UCM/KNX1.
  • Counters, Flags, Sensors, Physical Inputs, Outputs can be mapped to different KNX addresses compared to KNX to Comfort thus allowing different KNX control and status addresses. UCM/KNX1 did not allow mapping of these different Comfort registers to KNX. This means that it is no longer necessary to use Responses to send telegrams to KNX, although this is still possible. This makes programming much easier.
