The following section describes HSC data structures.

HSC APP Data Structure

Define a HSC App Data (configuration data, data type HSCAPP) when
programming a HSC. During HSC counting, the data should not be changed,
except if the configuration needs to be reloaded.
To reload HSC configuration, change the HSC APP Data, then call HSC
function block with command 0x03 (set/reload). Otherwise, the change to HSC
App Data during HSC counting will be ignored.
HSC1, HSC3, and HSC5 support mode 0, 2, 4, 6, and 8 only, and HSC0,
TIP
HSC2 and HSC4 support all counting modes.

PLS Enable (HSCAPP.PLSEnable)

Description Data Format
PLSEnable bit
This bit enables and disables the HSC Programmable Limit Switch (PLS)
function.
When the PLS function is enabled, the setting in
• HSCAPP.HpSetting
• HSCAPP.LpSetting
• HSCAPP.HPOutput
• HSCAPP.LPOutput
are superseded by corresponding data values from PLS data. See Programmable
Limit Switch (PLS) Function on page 159 for more information.
