For example, for UCM/KNX, KNX Group addresses can be mapped to Counter numbers. of the same Counter is mapped to UCM/Cbus, or UCM/Zwave, or IRIO functions, then if one device changes the value of the linked counter, then the other devices mapped to the same counter are also controlled by the counter value
In the example below, KNX group address 0/0/5 is mapped to a Counter in Comfort
When the KNX group 0/0/5 changes its value, eg 0 to 155, this value is saved in the mapped Counter
Also if the counter value is changed in Comfort by a Response or from other systems, the updated value is sent to the mapped KNX group address, si it is a 2 way link
If another UCM eg Modbus element is mapped to the same Counter, then that allows one UCM to send commands to the other extrenal device and vice versa, or Comfort can control both devices by changing the counter value
