4.3.3 DI/PI_Type003
• This type of pin is a ground referenced input (DI) including a pulse counting (PI) feature.
• Pulse inputs can be used as a 1 or 2 channel pulse counter and they have a possibility for
reset pulse. Possible software channels and pairs are listed in section
SW channels for
Pulse Inputs.
• The configurable features are controlled by a control signal:
• pull-up enable selection
• When the pull-up to internal +10V is enabled, it controls two input pins as one. The pairs
are indicated with lower case characters in the pin table's Group column in section
Pinout
Map.

Note 1: A pull-up resistor is not selected.
Note 2:When pull-up resistor is selected.
Note 3: Exceeding the max values might cause damage to input.
Note 4: These parameters depend on software cycle time.
Note 5: Applies to inputs used as normal digital input. Violating this rating may lead to application
program not noticing all input state transitions.
Note 6: Overload conditions
Note 7: Violating this rating may lead to system not recognizing all input state transitions.
Note 8: It is possible to configure a smaller minimum frequency for some of the pins, see I/O
table (Information column) in section
I/O List.
Note 9: tC denotes software cycle time.
Note10: Max value can be reached by 2-98% pulse ration.
