Using the High-Speed Counter and Programmable Limit Switch
UserInterruptPending
The UserInterruptPending status flag that represents an interrupt is pending
by the specific conditions.
This flag is used to detect in the user control program if an HSC interrupt is
executing and will be automatically cleared when the PLC completes its
processing.
UserInterruptLost
The UserInterruptLost status flag that represents an interrupt has been lost.
This bit is set by the PLC and applied by the user program.
LowPresetInterrupt
The LowPresetInterrupt status bit is set when the HSC accumulator reaches
the low preset value and the HSC interrupt has been triggered.
This bit can be used in the control program to identify that the low preset
condition caused the HSC interrupt and this flag would be applied by the
control program.
This bit can be cleared by the control program and is also be cleared by the
HSC whenever these conditions are detected:
• . High Preset Interrupt executes
• . Underflow Interrupt executes
• . Overflow Interrupt executes
