Motion in for high speed counting of digital input signals
Pulsed Input : Typically is associated with frequency, counting or totalization applications
Pulsed Input requires 1 Digital Input. After configuring in Setup Hardware, placing a Motion In Block brings up the following Dialog.
The Tag you select for ‘Count Value’ will store the Motion In’s count value. Count Value must be of the I32 Data Type. The Motion In block can be set to count up or down. A count is triggered by either a rising (0 to 1) value, or a falling (1 to 0) value. The ‘counter Input Bit’ that causes the count is the Digital Input that you selected in ‘Setup Hardware’.
Quadrature Input (A and B signals) : Provides the interface to incremental encoders for obtaining mechanical position data
Quadrature Inputs are used with incremental rotary encoders. Check out Wikipedia’s article on them to learn more. They require 2 Digital Inputs. Be sure not to use the same Digital Input for both Quadrature Inputs.
Start Counter :
Start Counter requires an I32 Tag to store the count in.
Stop Counter :
