need help I programming

Hi .

I need help .I have a program .I am stuck.

But I want that when B005 is 1 then Q1 must b 1.if B005 is 0 then Q1 is zero.

If I2 is 0 then output could be 1.

If I2 is 1 then output could be 1.

But if I2 goes to 0 after 1 then output should be zero after 3 sec.

Please guide me with positive approach.

I am beginner.

In general, for small logic optimization, analysis and synthesis I recommend you Logic Friday 1. It’s freeware and you can download it from: http://www.sontrak.com/downloads.html.

Another freeware option is SimpleSolver: http://www.simplesolverlogic.com

For your application, try to use edge triggered functions like NAND gate or the Wiping Relay with inverted Trg input. For more info double-click the function and then Help or go straight to help and look for the function in the content.

For Edge Triggered Wiping Relay: put 3s in TL and 0,1-0,2s in TH (don't care). I think you also need to memorize the status with a Latching Relay or a Pulse Relay.

If you don't have LogoSoft Comfort v8.0 (latest version) software go to:

http://w3.siemens.com/mcms/programmable-logic-controller/en/logic-module-logo/demo-software/Pages/Default.aspx

and download the demo version. Install the software, open the application and go to Help menu.

Select (click) Contents and start to read. At the bottom you have enough examples to practice.

With a file browser look inside the installation folder for \Manuals; inside you have LOGO! manuals in pdf format.
