5.2.3 Assigning addresses in programming mode
"Address assignment in programming mode" is suitable for Synco 700 type RM…
controllers, RXB/RXL room controllers, OZW77x central communication units and
area/line couplers and IP routers.
Refer to the individual product documentation for details of how to set a device to
programming mode on site. Often, as with the Synco 700 RM… controllers, the
button marked "Prog" has to be pressed briefly.
Only one device at a time should be set to programming mode.
Explanation: If two or more devices are set to programming mode, the service tool
cannot identify an individual device and transmit a device address specifically to
that device.
1. Set the required device to programming mode locally, e.g. press the "Prog"
button on the RMU730. The red "Prog" LED lights up.
2. In ACS Service select Plant > Edit device list… to open the "Edit device list" dialog
box.
3. The Programming mode… button is now available under "Address assignment".
Click this button to open the "Address assignment" dialog box.
4. Enter a device address in the range 1…253 (excluding 150), and click Write to
confirm.
5. Check: Once the new address has been adopted, the LED on the device should
be OFF.
