F-DI module
The channels of the F-DI module are mapped differently to the NCK/PLC-SPL
inputs $INTSE/INSEP depending on the selected parameterization.
• 2v2 parameterization
For 2v2 parameterization, the process signals of both channels in the F-DI
module are combined to form one F useful (net) data signal and thus
supply an SPL input data.

• 1v1 parameterization
For 1v1 parameterization, the process signals of both channels are
transferred from the F-DI module and can thus supply 2 different SPL input
data.
