I have just now started learning about PLCs. I
have done a lot of procedural programming, but
am new to programming using Ladder Logic.
I have read a couple of books, and have learnt
a lot by looking at
http://www.geocities.com/plc_guide/index.html
Now trying learn more by trying to understand a real program. In that program there are comments such as RESET_UNIT_PV, etc. which seems to set/unset one of the bits in the B2-file.
I have not yet looked at PanelView, so i am not
sure how this works. Can panelview modify
bits on a PLC (possibly by writing over the
network)?
This is program written for SLC-500 series of
processors. It is very much possible that that
is exactly what PanelView is for! It is just
that I have not gotten around to looking at it
yet. So far i only aware of I and O data files
as a way of doing Input/Output.
I apologize if this is too much of beginner quesion and is not appropriate in this forum.
Thanks!
