HSC Overview
HSC Overview
Concept
The HSC function executes the counting of fast pulses from electronic sensors,
encoders, switches, etc. The HSC function is independent from the XBT GC HMI
Controller scan time.
Two HSC types are available:
1-Phase HSC (see page 29)
2-Phase HSC (see page 37)
For information on the XBT GC HMI Controller general I/O configuration, refer to I/O
Configuration (see page 11).
Maximum Number of Channels and Operating Frequency
For information on the maximum number of HSC channels and their operating
frequency, refer to HSC General Characteristics (see page 28).
Use Case
The following graph shows a typical use case. The synchronized output changes
only when the counter value crosses the ON or OFF preset threshold values:
NOTE: The 1-Phase HSC up-counting or down-counting depends of the Mode
(see page 30) set from the HSC I/O configuration (see page 45) screen. Upcounting/Down-counting
is available with the 2-Phase HSC only. The 1-Phase HSC
offers up-counting or down-counting depending upon your selected mode from the
HSC configuration screen.
