    Hi Mik,

    How can I calculate value from another device? Let say I have 3 device and want to sum Total KW from each machine.

    Thank you,

    Hi Manjey,

    I tried like this. create new channel in Input channel machine 1. I put on the last table row no 163, channel type = real, object = Enterprise, Formula used = checked, Formula = Val(131)+Val(231)+Val(331). and I add on my table input channel 163. But when I open rapidscada view. the value just show —-. Is there any step that I missed?

    Hi,

    Set the type of channel 163 to “Calculated real”, and set Signal to blank.
