Hi,

Is the IEC61131 standard on PLC programming available online
or the document needs to be purchased?
Any easy to follow web site on this?

regards

It is a rip off, but what can you do?

You need to purchase it. It is a rip off as the document is a scanned document and therefore has no links or out line like the good .pdf documents do.

The specification also has flaws or holes. After reading it you will see why each manufacturer will implent the specification in a different way.

Hi,

I just learnt that the IEC61131 document cost US$176 from IEC's web site(www.iec.ch).

Hi,

Small error in my prev. post.
IEC61131-3 (part 3) costs US$176 not the entire IEC61131 document. There are totally 8 parts to this document.

A small, somewhat off the subject, rant. If national and international standards organizations wish to really expand the use of standards, then the standards specifications themselves should be free, if uploaded from the internet or for only the printing costs. The organizations should be supported by those wanting the standardization and/or those wishing to claim conformance to the standard.

$176 is a drop in the bucket if one is serious

It takes time/money to write the specification. Someone must pay for this. In the end, the OEM just passes the cost on to all of you.
