[DigIn x Debounce] sets a delay time to allow any bounce in the digital input to
settle out. This parameter has a range of 0 to 15.5 milliseconds.
When [DigIn x Sel] is set to “User Select,” the function of the digital input is
determined by the following:
• [DigIn x Data] determines any bits that should be permanently set. [DigIn x
Data] sets the value of [DigIn x User Data] except for the bit chose in [DigIn x
Bit]
• [DigIn x Data] determines the bit you wish to toggle based on whether the
digital input is on or off
• [DigIn x User Data] will have the same bits that are set in [DigIn x Data]. Then
the bit that was chosen in [Digin x Bit] will toggle based on whether the digital
input is on or off. A designation (sink) parameter is then linked to [DigIn x User
Data] so that it determines the value of that sink parameter
Configuration Example
DigIn 1 will be setup to determine the value of [Speed Ref Sel]. DigIn 1 will toggle
[Speed Ref Sel] between a value of 1 “Speed Ref 1” and 5 “Speed Ref 5.”
• [DigIn 1 Sel] = “User Select”
• [DigIn 1 Data] = 0000 0000 0000 0000 0000 0000 0000 0001
• [DigIn 1 Bit] = 2. This means when we toggle Digital Input 1, bit 2 of [DigIn 1
User Data] will toggle.
When Digital Input 1 is off [DigIn 1 User Data] will be equal to [DigIn 1 Data]. In
other words, [DigIn 1 User Data] will equal 0000 0000 0000 0000 0000 0000 0000
0001 (a value of 1).
When Digital Input 1 is on [DigIn 1 User Data] will be equal to [DigIn 1 Data] plus
whatever bit was set in [DigIn 1 Bit]. In other words [DigIn 1 User Data] will equal
0000 0000 0000 0000 0000 0000 0000 0101 (a value of 5).
[Speed Ref Sel] is linked to [DigIn 1 User Data]. Now [Speed Ref Sel] will toggle
between a value of 1 and 5.
