Chapter 4 High Speed Counter – 2080-MOT-HSC
Differences Between
Embedded HSC and Plug-in
Module
The following table lists the differences between the embedded HSC and the
2080-MOT-HSC plug-in module.
Counter Specifications
Filter and decode inputs: 3 input points A, B, Z
These input points may come from different types and configurations of sensors.
The user must configure the module to respond to the type of sensor connected
to the module as described below. This can be configured in the 2080-MOT-
HSC UDFB. From Connected Components Workbench Release 8.0 onwards, if
you have configured the plug-in for Feedback Axis, you can also edit the input
filter values in the plug-in configuration module properties.
Embedded HSC 2080-MOT-HSC Plug-in Module
Limited to 100 kHz Up to 250 kHz
12/24V input 12/24V input or 5V differential line driver
None Embedded rate calculation using “Per Pulse” and
“Cyclic” methods
Dedicated preset and hold inputs Configure either preset or hold inputs
None One 5/24V output
When using the 2080-MOT-HSC module, the high and low preset
status does not automatically reset. When using the embedded HSC,
it automatically resets when the high and low preset condition no
longer exists.
