23.1 General-purpose Input / High-speed counter
Function Summary
23.1.1 High-speed counter Function Summary
• It is the function which can perform high-speed count for input signal from sensor and
encoder.
• When the counted value is consistent with a target value, the special instruction (F166/F167)
which can change any output (Y0 - Y29F) to ON or OFF by interrupt processing are provided.
When the output changes to ON/OFF, you can use presets such as SET/RET instruction.
• Designate used channel and input with system registers. Designate output in case of
consistency with the operand of instruction.

23.1.2 Counting Range and Elapsed Value (Current Value) Area
• The high-speed counter’s elapsed value is stored in the special data register as 2-word 32-
bit data.
• When the power turns to OFF, the elapsed value area is reset. It is held when the RUN
mode is switched to the PROG. mode.
• The high-speed counter is a ring type counter. When the counted value exceeds the
maximum value, it is restored to the minimum value. When the counted value is lower than
the minimum value, it is restored to the maximum value.
