* If you enable diagnostics for multiple channels, you will receive an alarm surge on failure of the supply voltage because
each enabled channel will detect this fault.
You can prevent this message burst by enabling diagnostics for one channel only.
** The scope can be assigned for each channel during parameter assignment in RUN.
*** For the configuration as a 4 x 8-channel module, a maximum of 16 hardware interrupts can be configured (channels 0 to
15).

Explanation of the parameters of the DI mode

No supply voltage L+
Enabling of the diagnostics, with missing or too little supply voltage L+.
Wire break
Enabling diagnostics if the line to the encoder is interrupted.
Input delay
This parameter can be used to suppress signal disruptions. Changes to the signal are only
detected if they are constantly pending longer than the set input delay time.
Hardware interrupt
Specifies whether or not a hardware interrupt is disabled or with which of the following
events a hardware interrupt is generated.
● Rising edge
● Falling edge
● Rising and falling edge
