Local Mode

[Sean Wint]

I need help. I am interfacing with a agilent E3644A series power supply and I do not know how to set the power supply to local mode after it has been set to remote mode. I know how to do this via Interactive Control, but cannot figure out how to do this through the instrument drivers provided.

Thanks,

Sean

Have you looked in the User Manual to see if there is a command to accomplish this, such as LOC?

[Sean Wint]

Yes I have. They have example code for C, C++, Excell and Visual Basic. I also looked in MAX and searched for "LOCAL" and they had the command ibloc which works but only in the Interactive Control. I tried to input cod such as LOC, * LOC, ibloc...etc, but nothing seemed to work.

did you try
SYST:LOC

[Sean Wint]

which VI do I need to use to implement the SYS:LOC command

[Sean Wint]

It doesn't work...

[lmtis]

Assuming that you are using a GPIB interface, you would use the GPIB write VI.

Try sending it with MAX.

If the command SYS:LOC is in the manual, you would use either a VISA Write or a GPIB Write to send this. If you want, you can use the 488.2 function called EnableLocal. If you want, you can use the VISA GPIB Control REN function with a Go To Local value.

I am using GPIB by the way. I currently am using the VISA Write VI to send commands to instrument. The two commands found in the manual used to send the device into local mode are LLO (Local Lockout) and GTL (Go To Local). These are listed under Local Addresses. I try to send these commands, but an error occurs.

Here is page 92 from the E364XA users guide.  Perhaps it only works for RS232? As I now see it clearly states
