■ Comparison output reset
When the special internal relay turns on, the comparison output selected on High-speed Counter Settings turns off.
■ Reset input
When reset input is turned on, the current value returns to the reset value.
■ Preset value, reset value storage locations
The preset value and the reset value for the high-speed counter are stored in special data registers as 2 words.
When the 32-bit data storage setting in the function area settings is set to from Lower Word, the lower word is
stored in the first device.
■ HSC reset input and reset status
When the HSC reset input is enabled in group 1, turn on HSC reset input I2 to return the current value to the reset
value.
In this situation, reset status turns on for only one scan.
To use the reset input with group 1 single-phase high-speed counter, use I2 (group 2). When not using I2 as a reset
input, it can be used as normal input, high-speed counters, catch input, interrupt input, or frequency measurements.
■ Count direction flag
These special internal relays maintain whether group 1 current value count is being added or subtracted.
When these special internal relays are on, they indicate addition. When they are off, they indicate subtraction.
