Description
The Allen-Bradley 1756-HSC ControlLogix High-Speed Counter Module performs high-speed counting for industrial applications. 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.
The user 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.
The storage of count values can be manipulated. The 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 counted as 1 thru 16 million
- frequency - positive or negative depending on the direction of the rotation
