Chapter 6 Applied Instructions Symbol S ： Timer number (T0-T511) m ： Setting value of the timer D ： Output device Explanation 1. This instruction generates timing for the off-delay relay, the one-shot circuit, and the flashing circuit. 6_ 2. This instruction uses 100 milliseconds as the timing unit. If the setting value for m is 50, the time value is 5 seconds. 3. You cannot use this timer repeatedly. 4. D occupies four consecutive devices. 5. Before the instruction is executed, reset D - D +3. 6. When the conditional contact is not enabled and the value of the device meets one of the two conditions mentioned below, D , D +1, and D +3 are ON for m seconds before they are switched OFF.
When the conditional contact is not enabled and the value of the device does not meet either of the two conditions mentioned below, D - D +3 keep OFF. The value of the timer is less than or equal to m , D is ON, and D +1 is OFF. The value of the timer is less than m , D +2 is OFF, and D , D +1, and D +3 are ON. 7. When the on-line editing is used, Reset the conditional contact to initialize the instruction. 8. The value in m must be between 1 – 32767.
