1-1-2 Features
An interrupt task can be started when a built-in input turns ON or turns OFF .
Up to six interrupt inputs can be used.
Note The user setting in the PLC Setup determines if each input is a quick-response input, normal input, interrupt
input, or high-speed counter input.
A high-speed counter input can be used by connecting a rotary encoder to a built-in input. A CP1E CPU
Unit is equipped with more than one high-speed counter input, making it possible to control devices for
multiple axes with a single PLC.
Note The user setting in the PLC Setup determines if each input is a quick-response input, normal input, interrupt
input, or high-speed counter input.
• High-speed counters can be used for high-speed processing, using either target value comparison or
range comparison with the counter’s PV to create interrupts.
An interrupt task can be started when the count reaches a specified value or falls within a specified
range.
• High-speed counter input frequency (speed) can be measured.
The input pulse frequency can be measured using the PRV instruction (counter 0 only).
