The programming manual for ITG drivers should be available as a download on Agilent.com. At least it used to be there.
Also there's a Driver Writing Tool which is very useful for learning the language and was included with older versions of VEE.

This is a compiled language, so after you write the driver compile it using "idc.exe" which should be extent in your VEE install.
That will create the ".cid" that VEE can use.

Thanks to those that suggested solutions to my question concerning
generating a new file at some periodic interval (i.e. midnight). I have
settled on a method that combines suggestions and appears to meet my
needs. I'm generating a number of data files simultaneously and I didn't
want the application spending more time than necessary determining if it
was time for initializing new files. Clearly, every new file needs a
new name so using the time to generate the names on each file entry pass
does the trick but including "Build_Filename" as part of each file
generation thread seemed excessive.

Alternatively, in independent thread could generate the time dependent
part of each file name and the individual file threads could each simply
add their unique portion. This would seem to save some time but this new
thread would need to run frequently in order to catch the time interval
transition.

The solution I'm experimenting with adds a simplified version of the
concept Shawn suggested; it calculates the number of seconds until the
next file initialization time and uses this value to set a delay. When
the delay time expires, the variable part of the file names is generated
and, when used by each file thread, new files are started automatically.
This approach appears to work perfectly, at least for my incoming data
rates. Also, I've noticed that when looking at the CPU loading, I can't
see any difference between using this method and simply allowing
individual files to grow indefinitely.

The attached example shows the method for hourly initializations but
only deals with one data file and therefore uses a simple
"BuildFileName" method.

One final point - for my purposes, I seem to be able to get away with
closing each file after each entry. If I didn't do this, old files would
remain open unless a "new file name" test corrected this situation (see
Mike Asbery's "New File at Midnight" response).

Hi folks, this drives me crazy!!!?###@@@
Â
I now built up a small program which just sends MEAS:CURR:DC? to the 34401a on address 22.
As the built-in instrument manager of VEE told me (*checked it* by *IDN?) that I have two interfaces GPIB14 with 1422 and GPIB32 with 3222 -although I have only one interface built in, I'm quite sure about that!- , I took this all into the attached program. On both interfaces, the 34401a (after power on) went to DC-Current as ordered and took a measurement. The IO stopped after the talker-addresing of 22 (TALK 22) and a timeout-message came.
The instrument went into ERROR -410 when I started the program a new, because the outputbuffer was not emptied yet. This understandable. So I had to turn off power of the instrument and start allover again.
Â
I cannot understand, why there are two different interfaces present, with only one built in and why does only the sending work and not the receiving of data.
Â
Maybe somewhere in the *VEE-World* there is someone who may help me.
Please don't tell me to throw the computer into my dustbin, it is only 6 months old!

Peter,
Â
The first interface (1422) is built into the functionality of VEE to call the NI 488.2 GPIB drivers directly. The select code 14 corresponds to board 0, 15 to board 1, 17 to board 2, 18 to board 3.Â This was implemented back in the original versions of VEE-PC to be able to use the NI GPIB cards to talk to instruments.
Â
The second interface (3222) is a new function of the I/O Libraries to allow Agilent VISA/SICL to pass-through commands to the NI 488.2 libraries. At around the same time the NI libraries also contained a pass-through feature to allow the NI drivers to call Agilent GPIB cards.
Â
It appears from the GPIBREP.txt file that you are using a GPIB card thatÂ emulates the NI software by supplying it's own GPIB-32.dll. What may be occurring is that the supplied DLL is not implemented exactly the same as the NI version of the DLL, or at least requires some functionality that VEE does not call and is not required by the NI driver.Â But the VISA layer calls work since the supplied visa32.dll (as they list as 32-bit Forwarding VISA DLL) must comply with the industry defined VISA function calls/parameters.
Â
One thing I have found over the years is thatÂ some instrumentsÂ will respond to *IDN?, *STB?, and other standard function calls when not in remote mode, but will not respond to all other commands. Is the voltmeter going into remote operation mode?Â If not try performing a execute remote to the instrument first, or check if the supplied GPIB software has a setting to assert REN when SC (this is a software setting NI supplied software ahs available to set).

<div>Peter,</div> <div> </div> <div>I would check to maks sure you have the meter configured right and that all the proper sequence of commands are being sent. It seems to me in the manual there was a particular sequence of commands that had to be followed in order to get a reading using the "meas" command but then it might have been something else. All I can remember without digging through the manual again was that I jad missed one thing and my meter would not respond either.

Hi,

The vrf archive appears to be down.Â I remember someone telling how to programmatically edit the field name of a record.Â Something about converting the record into text and replacing the name.Â Has anyone tried this?

Â

Regards
