11-3 High-speed Counter Interrupts
High-speed counter interrupts can be used with any model of CP2E CPU Unit.
This function counts input pulses with the CPU Unit’s built-in high-speed counter and executes an inter-
rupt task when the count reaches the preset value or falls within a preset range (target-value or zone
comparison). An interrupt task between 0 and 15 can be allocated with the CTBL instruction.
11-3-1 Overview
Target value comparison Range comparison
The specified interrupt program can be started when the
present value of the high-speed counter matches a target
value.
The specified interrupt program can be started when the
present value of the high-speed counter enters a set range.
