Need Help!- Outputting Common variable values into a program

[yaji63]

Hi,

Does anyone know how to Output Common variable values into a program (with automated new program number OR an existing program itself) within the CNC memory ?

Thanks

Do you want to use the value of a common variable inside a program or want to print the values calculated in a program through RS232?
The first requirement is no big deal. If #500 contains 1.0, G#500 is equivalent to G01, and so on.
Use DPRINT for the second requirement.

I want to print the values into another program and not into RS232. This way i can transfer the program into my dataserver / flashcard / computer for further analysis. My machine is not connected through RS232 but is connected through Ethernet.

It looks like you don't really want to use variables, you want fixed a fixed program using values based on some variables that will not change during program running. This is much easier to do on your PC. Use "replace all" feature in your text editor to replace the variables with their desired values. As long as you keep your original macro program you can create as many fixed programs with different values as you want. You will lose your flexibility though, these programs will be "hard wired" for a specific set of values.
If the variables actually change during the program I am not aware of any method to extract the program that was created on the fly.

I'm not really 100% sure what you are trying to achieve, but if you are looking to extract data from a Fanuc CNC, look on this site. CNC Data LTD – CNC Data Collection and Monitoring Software | We can get any data out of CNC machines using ethernet connections and software such as Fanuc Focas

They can help you.

Use permanent common variables instead of common variables. A permanent common variable remains available to all the programs, even after a power cycle, and any program can change their values.
Actually, it is not very clear what you want to do, and why?

[yaji63]

I' am very much using the permanent common variables to monitor cycle times of the programs that run for a particular component.

These values are reset whenever a new component is machined. My idea is to output the variable values into a program so that this program can be downloaded onto the computer and then analyzed as well as for easing of data entry.

Not possible. The only way that you are going to get the values of the common variables or any type of variable "local" or not is going to be by sending them out via DPRINT function. Well at least on any Fanuc that I have worked on.

What model Fanuc are you using?

I heard somebody commenting that through ethernet one can have access to any CNC data. I do not know if the statement is true for variables also.

I' am using Fanuc 0i-MD which is supposed to be the latest among the 0i controllers. They claim that it has most features of 18i incorporated into it except for the true multi axis capabilities and some the HPCC options. I was only hoping against hope that i will find an alternative method to DPRINT.

I have also heard that Fanuc themselves have a software which when connected through Ethernet can give access to the CNC Data. I have asked for details and yet to receive a reply from them. And being Fanuc it will not be anything cheap at all

I have tried accessing data myself through this Focas 2 Ethernet but they Fanuc disables it when using in conjunction with a data server and thats the najor problem. Having one option ends up disabling another one !

I cant get a proper brochure for the software on the site which explains how exactly it works on Focas ethernet protocol. Our machine has a data server with it and i understand from Fanuc manuals that the Ethernet on CNC memory does not work when Dataserver is present on the machine. Has this software overcome that issue ?
