I found a link for English pages: http://www22.brinkster.com/anotherbr...ndex3e.htm

Kunal, the page does not include any design information. Just the functionalities of the card, manual and price.

"I even designed a parser in Java for my own PLC language"

Using Java versions of YACC and LEX, or from the stratch?

"Do you provide some code that the 8051 program interprets at run-time, or do you generate the Hex program for the 8051 itself? "

I also wonder this. Interpreting seems as the simplest -and slowest- way, but generating real 8051 code from PLC code should be hard if you program the PLC system code in C.

Right?
