6.5 Parameterising analog I/Os
6.5.1 2 analog inputs 0 ... 10 V (12 bits) - EPM-S400
Parameter data
During the execution time you can access the parameter data via the following data sets:
With the formulas listed in the following you can convert a digital value into an analog output value
and vice versa.
