F_M_DO10

Function
The F module driver reads the digital output values from the associated F channel
drivers (F_CH_DO) and writes them to a 10-channel, fail-safe digital output
module. In addition, it reads the error information of the module and makes the
data available to the associated F channel driver (F_CH_DO).
If there is a redundant module, the digital values are written to both modules.
The F module driver is automatically inserted at the end of the run-time group
which also contains the associated F channel driver F_CH_DO. The I/Os of the F
module driver are automatically interconnected and supplied with values.
The outputs DIAG_1 and DIAG_2, at which error information is output, are
important.
