About This Publication
The 1756 High-speed Counter module counts incoming pulses from pulse
generators, counters, limit switches, and other devices, and can either return a
count to the controller or activate on-board outputs for a specific action
depending on your application. In the rest of this manual, we refer to the
High-speed Counter module as the 1756-HSC module.
The chapters in this manual focus on the configuration and operation of a
ControlLogix
®
1756-HSC/B module, firmware revision 3.x or later using
RSLogix™ 5000 software version 18 or later. Additional capabilities of the
1756-HSC module are highlighted in the appendices, including revised output
tags and electrical schematics.
The table outlines the profiles for the 1756-HSC/B module based on your
firmware and software configurations.
If you are using the ‘original’ 1756-HSC/A module, with either firmware
revision 1.x or 2.x, see
for details.
