4.3.1 DI/PI_Type001
• 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 two control signals:
• pull-up enable selection
• input voltage range 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.
• The input voltage range selection controls two input pins as one. This local signal defines
threshold voltage levels for both inputs. This feature provides more flexibility to sensor
connections. The pairs are indicated with lower case characters in the pin table's Group
column in section
Pinout Map.
