How to read a specific value from yokogawa to labview

[Carmihaleo]

I would like to display the motor speed but it is not appear in the numeris preset and i used the synthax :DISPLAY:MOTOR:SPEED? but it is giving e errors

Which error do you get?

Does your (Yokogawa?) device understand that command?

Mind to attach your VI?

The (well, one of them, we're guessing the device) manual says ":MOTor:SPEed?"

So, try ":MOT:SPE?", ":MOTOR:SPEED?", not ":DISPLAY:MOTOR:SPEED?"

What exact Yokogawa instrument are you using?

We have several Yokogawa power analyzers in our lab. I took a peak at the manual for  our WT1600.

I have to ask if "DISPLAY:MOTOR:SPEED" is the command you really want?

The DISPLAY group of commands only changes what is on the instruments display, it does NOT retrieve the measurement so you can log, display, or process it on your computer in LabVIEW.

I suggest you do these things...

1. Read the Operators Manual for your instrument
2. Read the Communication Interface Manual for your instrument

All of our Yokogawa's came with a separate manual that covers the SCPI programming commands in depth

In the write buffer when i put only :MOTOR:SPEED? it gives me the settings for the motor but what i am looking for is the measurement

Hi Carmen,

according to this manual there is no "DISPLAY:MOTOR:SPEED?" command…

Measurements usually start with :MEAS: (or  :MEASure:).

So according to this WT1800 Precision Power Analyzer User's Manual (yokogawa.com), the communication manual is this one (I we previously linked to): WT1801E, WT1802E, WT1803E, WT1804E, WT1805E, WT1806E Precision Power Analyzer Communication Interfac...

Page 5-10 (44th page in PDF) covers measurement commands.

There are lots of things that are measured... So look in the manual.

can anyone share the write Command value code
