Dear all,
I am newbie to using open PLC and Rasberry pi. I wanted to test some code PLC code using Rasberry pi

and openplc software.
To get started i am using windows 8 32 bit 4gb Ram i3 processor. 
I would like to know what are the relevant software to be downloaded to test my first project.
https://www.raspberrypi.org/downloads/

Is there any simulator available for this application,
Is there any limitation of writing code. Means to say max size of code it can able to write.

You need to install Raspbian on your Raspberry according to the instructions on the link you posted. Then you follow the instructions on openplcproject.com to install OpenPLC on your Raspberry Pi (Getting Started -> Runtime -> Raspberry Pi). Finally, you download the OpenPLC Editor (Getting Started -> Editor) to your computer to create your PLC programs. The editor has a built-in simulator. If you're starting on this, the best way to go is to read the guides on openplcproject.com (Reference menu)

Is there any memory restriction for writing code. what length of code it will be supported from open plc.
like arduino and other development board it will have flash memory . max PLC length of prg can be written and tested with this software

As I said before, there are no restrictions. Your program can be as big as the size of your SD card. Given that an usual program has only a few KB and SD cards are measured in GB, I would say that the size limit is virtually infinite.

No, not extended memory. You need an SD card for the memory of the board. Without it, the board doesn’t boot
