Using the High-Speed Counter and Programmable Limit Switch
High-Speed Counter
Overview
All
X8 Series PLC
have
six 100kHz high-speed counters. There are three
main high-Speed counters (counter 0, 1, 2) and three sub high speed counters
(counter 3, 4, 5). Each main high-speed counter has four dedicated inputs and
each sub high-speed counter has two dedicated inputs.
Depending on the high-speed usage mode, the sub high-speed counter may
not be able to use.
High-speed counter specifications are as below:
• 100 kHz operation
• High-speed direct control of outputs
• 32-bit data (count range of ± 2,147,483,647)
• Programmable High and Low presets, and Overflow and Underflow Set-points
• Automatic Interrupt processing based on accumulated count
• Run-time editable parameters (from the user control program)
Programmable Limit Switch
X8 Series PLC
supports the Programmable Limit Switch function and it
allows you to configure the High-Speed Counter to operate as a programmable
limit switch or rotary cam switch.
High-Speed Counter (HSC)
Function Register
SFR (Special Function Register) of internal XGPC data table allows you to
access to HSC configuration data and control program.
If the PLC is in the run mode, the sub-elements of internal HSC SFR may be
changing.
IMPORTANT
The HSC function can only be used with the controller's embedded I/
O. It cannot be used with expansion I/O modules.
