simple traffic light for zebra crossing please

Hello guys… First at all, thanks to everybody in this forum who give me much supports and encourages, since my first visit to this forum last month. This site is very great, and you all is very supportive friends.
Well, today I tried programming my OMRON CPM1A PLC at the faculty. I programmed a simple traffic light, specific for use at Zebra Crossing. From this forum, I slowly learn about PLC, and now interest comes. Like this, I want to build a traffic light systems that when we supply power supply to the PLC, the GREEN light at 010.00 ON. Then , 20 seconds after we push ON the N/O push button at 000.00, the GREEN light will ON (1s) and OFF (1s) repeatedly for 10 seconds. Then , after that, the YELLOW light at 010.01 will light ON, at the same time the GREEN light OFF. Then, after 10s ON, YELLOW light will OFF, and at the same time the RED light at 010.02 will ON for 15s. Then after 20s ON, the RED light will OFF and the GREEN will again ON until somebody come and PUSH the push button at 000.00.

This is the program that I have done.

LD 000.00
OR 200.00
AND NOT 000.01
OUT 200.00
LD 200.00
OUT 010.00
LD 000.00
TIM 000 # 0200
LD TIM 000
SET 210.00
LD 210.00
RSET 010.00
LD 210.00
TIM 001 # 0100
LD 210.00
TIM 002 # 010
LD TIM 002
AND NOT TIM 001
OUT 220.00
LD 220.00
SET 01000
LD 220.00
SET 210.00
LD TIM 001
SET 230.00
LD 230.00
OUT 010.01
LD 010.01
TIM 003 # 0100
LD TIM 003
OUT 240.00
LD 240.00
SET 010.02
LD 010.02
TIM 004 # 0200
LD TIM 004
RSET 010.02

END ( 01)

When the above program is run , a few problems occur. First, after 20 seconds ON, the GREEN light only ON and OFF for once only. The rest 8s it OFF. This is what I hope you guys can help me. Then when, RED light OFF, the systems straight away stops. The green light did not ON. I have to OFF the PLC ( switch it to PROGRAM MODE) and then again turn to RUN mode to up the system. I do not know how to make the system works in loop or circle. I found one example which use 253.13 instruction bit, but I can not understand it>
So, could any one please give a hand to me?

Best regards
Razali

Thank goodness its OMRON, which I do not know, and a traffic light, which I hope never to know again.

I made this to keep the thread high because you have made a strong effort and I hope those that do know OMRON will offer suggestions.

Load Or And gates!

I havent seen this bloody things since tech school.

Please, if you use CX-programmer, use ladder programming and symbolic addresses as 010.00 'GREEN' so I (and many other hwo not ever seen OMRON-code) can easyly follow the code. Anyhow here are many people who can comment your statment list.

OK Guys, this is what it looks like in CX Programmer. Took me several minutes to cut and paste it together. I'll come back later and analyze it. Feel free to go ahead.

Just a quick one. He's got a coil of 10.00 and also Set 10.00 and RSET 10.00. Sounds like duplicate coil issue.

Another quick pass

He also SETs 210.00 in two places, but never resets it.

Probably a typo, but WHERE? In the code, or just on the site?

Obviously, the SET and RSET done above was wrongly applied.
