Internal Coils

Hello:

I'm new to Plus+1 and I come from a PLC background.  I was using the Boolean logic for converting some ladder logic, but I'm stuck with how to turn on an internal coil versus a real world output coil.

I would use the internal coil to latch the Boolean circuit and elsewhere in the logic to make other decisions.  Do I have to write to a bit in a word to represent an internal coil?

Thank you,

Mike Stiffler

Stefan:
Hello Mike,

PLUS+1 hasn't any "coils" like PLC. In PLC you give these "coils" a name like M1.0. In PLUS+1 you have to connect a green wire to the output of e.g. a SR-latch and pull that wire through you program where you want to read it.

I hope this will help you.

Best regards
Stefan

OK, I'll give the set/reset latch a try.

Thank you,

Mike

I came from the PLC world as well so I can sympathise with you.  As Stephan said you have to "name" your internal outputs and connect them to the AUTO bus in order to use them elsewhere in your program.

Mike Stiffler:
Hello:

Would it be possible to explain your concept a little bit more?  When I did a search for AUTO bus in the help guide nothing came up.

Thank you,

Mike
