  1. How to correct the real time in PLC CJ1M

    Hi all, I'm performing a project using real time function with PLC CJ1M. Actually, i know exactly how to make some actuators run when the time comes but the fact is PLC's real time is set incorrectly. Can you tell me how to set the time for plc again?? I tried to move a BCD value to the axiliary area A351 A352... but it didn't work. Pls help me.
  2. Programing for traffic light system

    I fixed that problem and now i want to program for traffic light system using real-time function. Can anyone give me some direction to do. I'm using PLC omron CJ1M. I don't know exactly what instruction or memory area, special bits i must use. Do i have to use Clock instruction or something else? Let's discuss this topic and guide me
  3. Programing for traffic light system

    Yeah, i got your point but i never learn something inflexibly. I tried to figure out the meaning of each instruction, never thought that "Software X doesn't have the exact function that Software Y has, i can't do this...."Now i'll attach a Doc file, someone can point out the mistake in my work, please!!!

  4. Programing for traffic light system

    Hi bro, I'm programing a traffic light example and then maybe develope to a project using the real time function. But i got some problems and i just need you help me with the easy part first. This traffic system has two crossroads. I intended to set the green,yellow ,red lighs of the first crossroad in the X-direction (horizontal) to 20s,10s,30s, and in the Y-direction (Vertical) to 20s,10s, 30s, respectively. Similarly, for the second crossroad in the horizontal direction i set green,yellow,red lights to 35s, 5s, 20s. In the vertical direction i set them to 15s, 5s, 40s, respectively. when i push start button i saw the all yellow and red lights lit immediately and i tried to wait if the green lights would turn on but it didn't. The system just stop after that in this situation. All yellow,red lights were lit permanently .Even i push stop button, there were only some lights turned off, the rest still light. Can you fix that problem for me and give me some dirrection to understand Compare instruction and timer instruction clearly. I just learned about OMRON PLC for a short time so i'm not good enough. http://www.mediafire...sx75pv0aq1b084s . This link is the instruction way using Compare instruction and timer http://www.mediafire...23230w9p1s61i3i . This link is the instruction way using timer and set,reset.... I want to program with compare instruction, it looks shorter than using the 2nd way
