“Function to terminal” (FTT) programming
The design behind programming of the digital inputs and
outs of the DM1 uses “function to terminal” programming.
It is composed of a terminal, be it a relay output or a digital
output, that is assigned a parameter. Within that parameter,
it has different functions that can be set.
