Hiding voltage error messages
On delivery from the factory, a peripheral fault can be
triggered by various causes. Voltage faults, however, can be
suppressed with the DIL switch setting on the bus node.
Note
Independent of the setting of DIL switch 2.1, the errors are
entered in the status bits.
The system is not stopped due to peripheral faults. You can
define the reaction to peripheral faults in the user program. A
peripheral fault is also acknowledged in the user program.
