are you sure that you even NEED to use FBD and STL for your program? ... most applications don’t even use those ... instead most programs use plain Ladder Logic ...
you’ll need to enter the I/O modules MANUALLY ... do you already have the hardware available? ... if so, use RSLinx to examine each module and get its model/catalog number and its revision number ... hint: right click on the module in RSLinx and go to properties ... you’ll need to know that information when you add the module to the I/O list ...
there are MANY ways to make a tag ... in most cases you’ll right-click on an instruction (example: an OTE) and select “New Tag” - then type in a name ...
we can’t really help you very much unless we know more about what you’re trying to do ... DO YOU or do you NOT already know how to use RSLogix5 and/or RSLogix500? ... we can base much of what we tell you on how RSLogix5000 is DIFFERENT FROM or SIMILAR TO the other packages ... IS THIS or is this NOT your first experience with Allen-Bradley? ... again, the way that we explain things will be different if all you know so far is Siemens ...
we’re trying to help - but so far you’re only asking VERY general questions ... in that case, all we can do is offer general suggestions ... if you can give us specific questions, then we can offer detailed “how to” advice...
so do you have the hardware available? ... if so, what are the catalog numbers - and how are the modules arranged? ... if not, do you have a list of what I/O will eventually be installed? ...
we need details in order to help you ...
