DL-06 Wiper Motor Program

[Dobis]

Hello, all.  I fairly new to ladder logic, and need some help. 
I am writing a program for a rear "rise up" wiper motor (automotive). Which means that when it is parked it moves off the glass. When it is in "wipe" mode, it moves onto the glass and a computer switches direction of the motor when X1 is to ground (smaller angle than park so that it does not go off of the glass at each wipe). I need to be able to switch direction of the motor when X1 is to ground, but also include a 25ms delay before switching direction. Then I need to repeat the switching each time X1 goes to ground.
Thank you in advance for any help.  I am about to throw this thing out the window.

I assume this is the same question as is being answered at plcs.net. You should either stay on that forum, refer to it from here or at least provide all the information (steps, schematic) as last requested there.

Yes, this is the same one.  I was hoping there may be a person on here that does not go to the other forum that may be able to help me.  I apologize if I have wasted anyones time or resources.  I am just in dire need for help.

Dobis,

As Bernie mentioned all the details need to be laid out on the table before starting. Correct me if I have any thing wrong.

1. You have a motor that needs reversing.
2. There is only one input. When the PLC sees this input you want to wait .02 seconds before alternating the state of the output.
3. There is only one output.

Presuming I have everything correct I think this will work. Copy and paste this text below into notepad. Then open a new project in Direct Soft File, import, program, find the notepad file and click on open.
