Parameterizing the digital on-board outputs

Parameter assignment
A digital output from the local I/O is required for the switching signal.
For this, at least 1 digital output byte must be defined through the following machine data:
MD10360 $MN_FASTIO_DIG_NUM_OUTPUTS ≥ 1 (number of active digital output bytes)

Parameterizing the switching signal

Output number of the switching signal
Once the compile cycle has started up, the following function-specific machine data appears
in the channel-specific machine data:
MD62560 $MC_FASTON_NUM_DIG_OUTPUT (number of the digital output of the switching
signal)
The number n of the on-board digital output through which the switching signal is to be output,
must be entered in it:
n = 1, 2, 3 or 4
Disable
Entering the number of the digital output n = 0 deactivates the function. No message or alarm
is output.
Effect on other output signals
The hardware-timer-controlled output of the switching signal at the parameterized output
delays the signal output for the other digital on-board outputs, e.g. due to synchronized
actions, by 2 IPO cycles.
