6.4 1756-HSC Counter Card Configuration
This section will describe how to set up the Rockwell Automation High
Speed Counter card (1756-HSC) and the conveyor.
6.4.1 Wiring the 1756-HSC
The HSC card can be configured in several different ways. Each HSC
card supports two independent counters. The setup described in this
document uses only one of the two counters.
Each encoder that is connected to a conveyor needs one counter.
MLX200 is capable of tracking 2 conveyors per system. For a given
encoder, its wires should be tied to the HSC in the following manner.
• HSC card Input A: Tied to conveyor encoder
• HSC card Input B: Tied to conveyor encoder
• HSC card Input Z: Tied to photo switch or any other input that acts as
a trigger for object detection (could be a vision system)
Refer to the HSC USERS GUIDE SECTION 4 for details on wiring an
HSC card to a conveyor.
The Z input is used to automatically latch the conveyor position in the HSC
card. See the HSC USERS GUIDE PAGE 20 for details on this mode of
operation.
6.4.2 Configuring the 1756-HSC in RSLOGIX
To add an HSC to the project, right-click on the Backplane in the Control
Module Organizer, select “New Module” and navigate to the HSC card,
see Fig.6-6 "Adding the 1756-HSC Card to RSLogix":
