Line couplers

The area and line addresses for the area/line couplers can be set with "ACS
Service 7.0 SP1" (SP1 = Service Pack 1).
If ACS Service 7.0 SP1 (or a later version) is unavailable, the area and line
addresses can be set only via ETS.
In technical terms, the coupler devices are identical. Whether they operate as area
couplers or line couplers is determined by the addressing process.

• Line couplers

In the case of the Synco bus devices, only the device address needs to be set. The
Synco bus devices adopt the area and line address dynamically from the area and
line couplers.
Area and line addresses can be set with the coupler concerned in programming
mode.
Only one coupler at a time should be set to programming mode.
To switch the coupler to programming mode, press the learning button A5
("learning button A5" is a term in the product and applications description enclosed
with the Siemens line/area coupler 5WG1 140). Press the key again to revert to
normal operation.
LED A4 (above the "learning button" A5) indicates whether the coupler is in
programming mode:
• LED off
Normal operation (communication via KNX)
• LED on, red
Programming mode (LED is extinguished automatically
once the device address has been adopted).
The coupler switches to programming mode only if the bus power is available.
