I'm a beginner in learning PLC on my own. I've no any branded PLC software to check my programmes and trial Projects. My friend guided me to download the PLC free software which are available in some websites.
Will it work out to check my sample programmes and projects which are based on AB PLC programmes (B'cas I'm learning the AB based PLC).

If you post your work here, there are probably people who can test the logic. There are certainly people here who will offer constructive criticism!

if you haven't already been to www.thelearningpit.com, click the link and go there now and try out the free LogixPro demo version ... it's not EXACTLY the same as Allen-Bradley - but it's VERY close ... once you've worked through the free demo, decide whether you want to purchase some more projects ... or come back here and ask for some more advice ... we can tell you more about how to proceed from there ...
