Master/slave program

Hi Everyone, I just wanted to confirm my testing that the program will remain on the processor(Axcent-III) when I change it from a Master to a Slave unit and then back to a Master. The reason is I wanted to install NI-700's in my Axcent-III rooms and make the Axcent-III's Slaves. But if for what ever reason the NI-700 may crash I want to be able to just make the Axcent-III the Master again to get the system up. My testing shows I can do this but I wanted this confirmed by someone else. :rolleyes:

    AFAIK the Base Device number of the AXcent3 is saved in EEprom, so once set to base address >1 (to become AXlink bus slave) it will never switch back to base address 1 (back to AXlink bus master). So it should never happen that you'll have 2 AXlink busmasters the same time.

    Your program will still be stored as long as the batteries are good and the power will not fail.

    You are correct. The program will stay. All you will need to do is <SET BASE DEVICE NUMBER 0> from a terminal and your program will return and the Axcent 3 will be the master. I have been doing a lot of this lately.

    Thanks for the confirmation. It seems to be a reasonably cheap way to add the power of netlinx with an existing system.
