7.1.5.3 Freely assignable "analog" inputs (FAI)
4900Str038
FIG 7-11 FAI assignment with factory setting in configuration C005 = -11-
With each configuration changeover the corresponding analog signals are
assigned to the signal inputs - according to the configurations -. It is also possible
to reassign the inputs according to your application.
An analog signal can only be assigned to one function. If an analog singal has
already been programmed for the selected signal input, the previous assignment
will be overwritten.
A prioritization of the FAI ensures that terminal signals (X1/1 ... X1/8, X5, X7, X9)
can be used even if the operating mode C001 is set to interface or keypad control.
If an analog signal is assigned to a code, this input code is for display only. If the
assignment of the analog signal to the code is deactivated (e.g. by reassigning the
analog signal), the code stays on the value valid at that time.
If the input code is not linked with an analog signal, it can also be assigned to a
constant value which can also be stored in EEPROM under C003.
Exception: Parameters cannot be stored in codes C046, C047, C049 and C392.
The assignment of an analog signal to C270 or C271 (A/D-converter) enables a
digital evaluation of the analog input signal via interface.
