A good PLC simulator

Hello People,

I am new to this field of Automation and PLCs.I ahve ben searching for a good PLC simulator that I cna download for free from the net.I downloaded a few like PicoSoft(AB),PSIM,CSIM.But what I find is that most o these do not contain any Funtion Blocks for carrying out arithmatic or comparision operations.The most complex task that I can simulate is using Timers.

Can anyone suggest where from can I download a free program that that contains all the elements necessary to practice LD programmimg.

Thanks for your suggestions in advance.

Unfortunately, you can not get much of anything for free. That is what capitalism is about, even where there is no such thing.

Omron have a very good one but you would have to buy CX-One. Not much for free these days.
