F_M_AI6

Function
The F module driver reads the analog values (non-linearized values) and error
information of a 6-channel, fail-safe analog input module and makes the data
available to the associated F channel driver (F_CH_AI).
If there is a redundant module, the analog values of both modules are evaluated.
The F module driver is automatically inserted at the beginning of the run-time
group which also contains the associated F channel driver F_CH_AI. The I/Os of
the F block driver are automatically interconnected and supplied with values.
The outputs DIAG_1 and DIAG_2, at which error information is output, are
important.
