Chapter 6 Applied Instructions Symbol S ： Time after which the output device is ON D 1 ： Current time D 2 ： Output device Explanation 6_ 1. This instruction switches the output device specified by D 2 to ON after the amount of time in S . 2. S : The time after which the output device is ON (Unit: Hour) The operand S used in the 16-bit instruction must be between 1–32,767. 3. D 1 : The current time (Unit: Hour). The value in D 1 must be between 0–32,767. D 1 +1: The current time which is less than one hour (Unit: Second). The value in D 1 +1 should be between 0–3,599. D 1 +2 is for system use only. The value in it cannot be altered when the instruction is executed; otherwise, an error occurs.
cleared to 0, the timer starts to count again. When the current time is 32,767 hour 3,599 second, the timer stops counting. After the values in D 1 and D 1 +1 are 4. When the time for which the input contact has been ON reaches the setting time in S , the output device is ON. Before that the output device is not ON. This function allows you to manage the running time of the machine and maintenance. 5. After the output device is ON, the timer continues to count.
