Introduction
What is a High-speed
Counter Module?
Module Features
The high-speed counter module performs high-speed counting for industrial
applications. This chapter provides an overview of the design and features of
the module.
The module counts pulses by using a Counter or Frequency operational mode.
The counts are presented as either 'accumulated count' or 'frequency'
depending on the mode that is configured for the module.
You can choose from either one of three Counter modes or one of three
Frequency modes when configuring the module. The operational mode that is
selected determines how the pulse count is stored and the behavior of the
outputs.
You can manipulate the storage of the count values (detailed in
module evaluates these count values against user configured presets and/or
values, thus the response time for activating outputs is performed at a faster
rate than evaluating in the controller.
Configuration tags, which are automatically installed with the module during
the initial download of the programming software, determine whether the
module interprets pulses as:
•
accumulated count - values can be 1...16 million.
•
frequency - positive or negative depending on the direction of the
rotation.
