Perhaps this has been asked numerous times before .
I would really appreciate if some one can generously point out to me the places where I can find good Application Notes and Technical Literature on Modbus and Lonworks.
More questions :
1)Are these very widely used in automation industry?
2)How long have they been around and any danger of being superseded
or obsoleted ?
3)Are these proprietary or open standards ?
There are a number of Serial-Interface LCD Modules that operate on RS232 and
RS485 standards : can these be linked via these Modbus / Lonworks ?
Many thanks from a newbie.
Thank you in advance,
Alex
