118 Using the High-Speed Counter and Programmable Limit Switch
HSL - High-Speed
Counter Load
Instruction Type: output
The HSL (High-Speed Load) instruction allows the high and low presets,
and high and low output source to be applied to a high-speed counter.
These parameters are described below:
• Counter Number - Specifies which high-speed counter is being
used; 0=HSC0 and 1=Not support.
• High Preset - Specifies the value in the high preset register. The data
ranges for the high preset are -32768 to 32767 (word) and
-2,147,483,648 to 2,147,483,647 (long word).
• Low Preset - Specifies the value in the low preset register. The data
ranges for the low preset are -32768 to 32767 (word) and
-2,147,483,648 to 2,147,483,647 (long word).
• Output High Source - Specifies the value in the HPO - high preset
output register. The data range for the output high source is from 0
to 65,535.
• Output Low Source - Specifies the value in the LPO - low preset
output register. The data range for the output low source is from 0
to 65,535.
