how to change the address of a CI801 module in control builder
it's a 2 step process.
First you need to change the slave(CI801 here) address from webserver to whatever number you want. This is done either through "set slave address" menu or on the slave from rotary/DIP switches. reset the slave power after this. confirm the change in webserver "livelist".
Second you have to change the logical position of slave in control builder hardware topology. right click on the concerned slave and select "move to" then assign the required address. See attached pic for more detail.
