Programming with Focas library

Hey guys, I'm new to the forum and I'm an ME student interning at a manufacturing company. We use mostly 4 axis machines with Fanuc controllers. The project I was just given was to use the Focas1/2 libraries and create a program that will display simple actions (spindle on/off, etc.) of the machines at any time. I have been researching and reading through the Focas documentation but I cannot figure out how to even start this project. I have done a little VBA and C++ and plan on using VB.NET for this project, but I am no programmer. Any help that you guys can provide or even just pointing me towards some tutorials would be amazing.

Thanks!

First Code in VB6 for Focas; Just in ordre to test the connection between your PC and the NControler

'---------------------
' Ethernet connection
'---------------------
' allocate library handle 3
Declare Function cnc_allclibhndl3 Lib "fwlib32.dll" (ByVal sIPaddr As String, ByVal nPort As Integer, ByVal nTimeout As Long, FlibHndl As Integer) As Integer

Private Sub Form_Load()
Dim LibHndl As Integer
Dim Ret As Integer

Ret = cnc_allclibhndl3("192.0.0.1", "8193", 10, LibHndl)

End Sub

Can u be little more specific with a sample code ??

Hi,
although we're doing C++ programming the following might help:

You can also take a look at the FOCAS documentation here:

Hi,

i'm a bit in late :p

I'm trying to create a program (VB and Focas) whit the purpose to edit the part program from pc.

First of all I've tested the Focas function and the IP setting on CNC trough a free demo application (Opn Communications): all works!

Then I use command cnc_allclibhndl3 from my VB's program but it return me error number -15: "There is no DLL file for each CNC series corresponding to specified node"..
What is mean?? I've incorporate in the folder of my VB's project the file Fwlib32.dll. Do I need some other library files?

Thanks!

Yes! there are other .dll than the fwlib32.dll, it depend on the control you're using

Thanks Vincent for the answer.

I use a 31 series, so I put in the same folder (bin\debug) of fwlib32.dll the file fwlib31i.dll but the result don't change, always error number -15. I tried to add also the files of the whole series but nothing.

Instead, if I add the files fwlibe1.dll and fwlib32.lib, running cnc_allclibhndl3 takes longer time and returns error number 172031984 (???). I don't understand :confused:

According to my documentation, with a 31i control you need the FWLIB30i.DLL, if it's a FS31i, you need the FWLIBNCG.DLL.

I'll try with the fwlibncg.dll.
Is it enough to put it in the folder or do I have to import it via vb code?
Could you send me documentation via private message please? What I had was lost who knows where...

I am also trying and getting error LNK1104,i have tried my best but in vain. Can You please suggest me how did you link Fwlib32.lib file in Linker-Input(Is there any special way to provide path).Kindly assist as you have crossed this stage.
Anyways for error -15 I think you need to copy Fwlibe1.lib into debug folder where is your .cpp file.

Kindly someone suggest me how to get rid of LNK1104.This error has ruined my life...������������������������..I am simply copying path and pasting into Linker- Input and General.Looking for some assistance from you guys. Thanks in advance

Hey folks,

If anyone is looking for a Focas programming tutorial for .Net I have started a series of posts on my blog. Check it out and let me know what you think. If there is anything you want to see or think should be added, let me know.

I'm wondering if .NET delivers a good performance for fast data acquisition (mostly machine positioning around 1kHz). Anyone here knows?

Thanks

The problem isn't .NET it's the network connection. The execution of your .NET code is going to be faster than a network response by an order of magnitude. So you should be asking yourself about the latency of the connection between the machine control and your PC.
