    Counter n B can control the direction of counting in edge counting applications. Use the A, B, and Z inputs to each counter when measuring quadrature encoders or measuring two pulse encoders.

    Routing Signals to A, B, and Z Counter Inputs

    Each counter has independent input selectors for each of the A, B, and Z inputs. Any of the following signals can be routed to each input:
    • Any PFI terminal

    • Analog Comparison Event

    Routing Counter n Z Signal to an Output Terminal

    You can route Counter n Z out to any PFI terminal.
