Pulse Input Channel/Module Blocks

PICFASTCUTOFF (Pulse Input Channel with Fast Cutoff)

Description

Standard Interface to channels 6-7 of the Pulse Input IOM.

Function

The three main functions of channels 6-7 are:

•

Pulse Count (PULSECOUNT) – both raw count and Engineering Unit converted values.

•

Frequency value (PV) in Engineering Units

•

Digital Output (fast cutoff)

Inputs

If the Pulse Input Channel with Fast Cutoff is running it fetches AVRAW, AV, PV, TV and SO from its associated Pulse 
Input Module.  If the associated IOM does not exist in the CPM, fail-safe values are set.

Outputs

After Input Processing, the Pulse Input Channel with Fast Cutoff will send commands to the IOM function block.
If multiple commands are sent to the device, the execution order in the Pulse Input firmware will be:

1. Reset Counter
2. Write Output Value
3. Write Target Value

Associated
Block

1757-PIM and  Pulse Input Totalizer.
