Question:

How to compile the time relay

I was beginner PLC, with Delta PLC to do programming, with time relay software is not, please refer to the predecessors

Answer:

Delta programming procedures for programming time relays Delta PLC timer is 1ms, 10ms, 100ms as a time unit, the timing method to take a few times, when the timer value = set value when the output coil turns on, set the value of 10 decimal K value, also Available data register D as setpoint. Actual setting time of timer = time unit * set value. Programming by its nature can be divided into: 1. General timer: Generally, the timer is clocked at the time of the END instruction. When the TMR instruction is run, if the timer reaches, the output coil turns on.

Explanation of program: When X0 = On, the present value of the timer T0 is counted at 100 ms. When the timer now value = set value K100, the output coil T0 = On. When X0 = Off or power failure, the current value of timer T0 is cleared to 0 and output coil T0 becomes Off.

2. Integral timer The accumulator timer counts once when the END instruction is run. When the TMR instruction is run, if the timer reaches, the output coil turns on. Programming the ladder diagram below: Explanation of program: When X0 = On, the present value of the timer T250 is counted at 100 ms. When the timer now value = the set value K100, the output coil T0 = On. When the time is in the case of X0 = Off or power failure, the timer T250 is suspended and the current value is unchanged. Coil T0 = On. Specified value of the setting method: Actual setting time of the timer = Time unit * Set value. 1. Constant specification K: Set value Specify the decimal constant K directly. 2. Indirect designation D: The setting value is indirectly specified with data register D.
