CUE relayCUE-8 - Manual (Page 18)

6. Exchange of relayCUE-8 in existing
installation
There are two ways of replacing the relayCUE-8 unit in the existing installation:
1. The best way of making such exchange is replacing the relayCUE-8 by the new one physically,
and then make change in project programming. As soon as the unit with new UnitID is put in
place of the existing one in the project, the only thing that needs to be done is go the
properties of the exchanged unit and enter the new UnitID there. The project then needs to be
compiled and downloaded to the controller in the system.
2. The exchange described in the previous point is not always possible, for example if project
programming is missing, or if it is not possible to do new compile and download. In these
situations you must know at least the Address and Bank of the replaced unit. If you know these
parameters, you can just replace the unit in the system physically and set the Address and
Bank parameters manually using the buttons on the front panel – as described in chapter
“Front panel description”. After parameters have been set correctly, you must reset the
controller in the system and all parameters will be renewed in this unit according to the settings
in original programming.
To explain how the system works in such situation:
The UnitID of this new relayCUE-8 in the installation is unknown to the currently running
project and so the parameters Address and Bank remain unchanged (as explained above). All
the remaining functions are based only on these Address and Bank parameters, so all the
commands and system settings will be accepted by this new unit in the system, and the unit
will act exactly as the replaced one, without the need of reprogramming.
