PLC help!!!!
Hi,
I need some help on plc. i have been given a ladder logic to make.I have made is but in the end we have to make a little change in it. The parameters are as follows:
Inputs: Start, Stop, Manual and Step
Outputs: Out1, Out2, …, Out8
Relays: Run
Timers: Duration
Sequencer: Seq
0.5s is a half second timer that is activated here.
Now the problem is:
How can you change the circuit so that the sequencing stops when the duration timer has reached 0?
Now what i have to do is change the circuit so that when the timer reduces to zero, all the outputs become deactivated and the sequencing stops until the start button is activated again. I dont know how to solve this now?
any one have some ideas.I also attached the diagram.
Thanks.
