Dear sundar Please send us the original logic you tested with S7 200.The logic attached may not work because TON needs trigger to be active till 2 seconds and also note that trigger and reset can not be same signal at the same time. PLC clock memory also provides pulses likes you want but the longest pulse provided by PLC is 0.5 HZ, one second on and one second of and this is repeated with period of 2 seconds.Check the attachment for a method to generate a 2 second on and off as you like.It is also to generate this by 2 timers.

Dear sundar check the following link.I think the program discussed there is better and working version of what you presented here.Take a look for checking similarities. Why doesn't this work?BR |

@ hdhosseini : "Please note that branching as you did in your original program is not permitted in STEP7" You mean s7-300 or s7-200? |
