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 of the digital output n (where n = 1, 2, ... 4) via which the switching signal is to
be output must be entered in the machine data.
Properties of the switching signal
In the context of the general properties of digital output signals, the switching signal
properties are as follows:
• The number of the digital output can be changed from within the part program.
• The digital output can be disabled from within the PLC user program.
• The number of the digital output cannot be changed from within the PLC user program.
Deactivating the switching signal
Entering the number of the digital output n = 0 deactivates the function. No message or
alarm is output.
