The output is held until it is reset. The devicekeeps on counting even after “n” has been reached.(2) The counter reverts to “0” after it has counted to the end of the valid range, but output control isstill maintained. However, the output turns OFF if the count value or the preset value arechanged.●Change the Preset ValueIt is possible to change the preset value even during counting. However, please note the followingpoints.◇When the pre-scale value is “1.000” (PSCL=1.000).(1) If the preset value is changed to a value lower than the count value, counting will continue until itreaches the end of the valid range, returns to “0” and then reaches the new preset value.(2) If the preset value is changed to “0”, the counter will not begin counting at “0” right away. Instead,counting will continue until it reaches the end of the valid range and then it will start countingfrom “0”.(3) When the count value is fixed, output is changed according to the changing of preset value asbelow. If the preset value is changed to a value lower than or equal to the count value, the output is ON.（Count value ≥ Preset value） If the preset value is changed to a value higher than the count value, the output is OFF.（Count value < Preset value）◇When the pre-scale is not “1.000”. （PSCL≠1.000）Even if the preset value is changed after counting to the end of the valid range, the output is notchanged.
