■Operation Description
The content of the operation when ON and when OFF is as follows.
Operation when ON
High-speed counter current value counted -1 when input A phase ON
• Setting is ignored for counter other than 1-phase 1-input (S/W), internal clock.
• These devices also operate when the FX3 compatible high-speed counter function is valid.
■Update timing
The timing of device update is as follows.
ON
When ON by the user (update by END processing)
Can also be modified while the high-speed counter is operating.
High-speed counter preset input logic
These devices are used for setting the preset input logic.
