FANUC Ladder III

[mr_electrician 9]

Hello, can anyone tell me how to read the address map section. To be more specific, I know that if an R bit is used it will show a dash ( - ). But what does it mean when it shows a * ? Also how do you know what is being used as a word or double word? Edited 30 Jan 2008 by mr_electrician

_0130150623_001.pdf Are you using Proficy ME? If so, I believe that the * indicates a bit or word is being used and the (-) indicates that the word is not being used. Also, if you view the usage report for an R register, the * will indicate that one word is used. The #* indicates a double word. I have attached a pdf file showing a usage report. The * indicates that the inputs are being used. Regards Edited 30 Jan 2008 by KP_EENG

I am using whats called Ladder III. It is used for Fanuc CNC controllers to program the plc part of it. What you attached is different than what Ladder displays but I think that the idea would be the same on the identity of whats used as a bit or a word. Thanks for your help.
