This is the ABB CoDeSys software
this is an example of a structure text program
variables are at the top
programs in the second window down
here's an example, same thing variables, ladder logic
pretty much typical of what you see
here's a continuous function chart program
the interim variables are not necessary because you can drag a line from one block
right into the next
take a quick look here at the
visualizations feature with the CoDeSys software,here's a visualization screen
it's very simple and easy to program, if we take a look at
one of the items here on the display we'll click on
this particular variable
which are listed here
we'll just hit F2
we can bring up our global variables, individual program variables
which are listed here
and then we also have library files as well that can be pulled from
so there are lots of choices, it's quick and easy to make up screens for
troubleshooting and commissioning
your plc and make it very simple for you to use
okay this is our data
resources tab, we have our global variables here
so we have global variables list
we also have our hardware information here
some tools for communications eds configurater
device net
we also have the plc configuration which is in tree format
where we can see the hardware listed
look at a point-by-point list of the inputs this is also where we can
do our selection
of the channel and what the output or input
value of that channel will be or that particular point
we also have the
target settings where we can change which plc processor
it's just a matter of one change
and doing a recompile
we also have task configurations where we can do time based tasks..dwagner@techniconiec.com
