Pulse Input (PIN) function block

The Pulse Input (PIN) function block is an I/O block used for pulse count applications. It provides analog input values from Pulse Input channels on the Multifunction I/O card.

The PIN function block supports block alarming, signal scaling, signal filtering, signal status calculation, mode control, and simulation.

In Automatic mode, the block's output parameter (OUT) reflects the process variable (PV) value and status. In Manual mode, OUT can be set manually.

To support testing, you can enable simulation. This allows the measurement value and status to be supplied manually or from another block through the SIMULATE_IN input.

The following diagram shows the internal components of the Pulse Input function block:
