[omar zedan]

Dear All
I have in compact control builder AC800M software
In hardware config. of analog input module AI801
In setting tab parameters called
(Activate channel1....Activate channel2......Activate channel3.............................Activate channel8)
and the value of this parameters are true.
What dose this mean?????????????
Thank you

I guess it means that the channel is activated and incoming signal value transferring to the connected variable (RealIO).
If the channel deactivated (activate channel = false) the incoming signal is ignored.

how can I make the channels of AI801 analog input module read 4-20mA from 4-wire transmitter?
