Program that can log/control many multimeters and other devices.

1) Device just loaded
2) After logging has been started manually
3) When logging is finished and the table contains data.

You forgot to restart TC between the 3 test, the first test did the configuration, the other might not have done anything.

Sorry about this. I made a new one. I hope it is OK now?

@HKJ what can I do to help diagnose a TestController memory leak?

I have two situations that lock up TC / javaw with an obvious memory overflow (using SysInternals Process Explorer to examine Private Bytes / Working Set size

I will have to look at it.
I doubt it is a memory leak, Java do generally not leak memory, but it might be a hung thread (And the thread may hold the memory).

Using 330MB is not that bad (At least on my computer with 32GB/64GB), but TC slowing down is bad.

I've got huge RAM as well. Plenty of spare memory, so you're correct that (unless Java has an artificial limit) that wouldn't be it.

Note too: I've got a fast computer. It has plenty of idle cycles when these lockups occur. TC isn't just slow. It's 100% nonresponsive. I can't even close using the normal close-window actions (eg on right-click tray.) I have to use a task kill.

Definitely hung somewhere: zero cycles on any TC-related threads.

Maybe procmon will show something. If I can grab a few Round Tuits I'll try to diagnose further

You should pay attention to see if your lockups occur with specific devices only.

Definitely a hung thread, they are often very hard to find, except if I can reproduce it.
I did try you first description, but did not see any issues.

When I write a negative signed integer to a holding register using the modbus driver, will the highest bit be automatically set ?

If no, what do I need to do to set the high bit of double byte value? and how to do this in the #scpiCmd (value) statement ?


For reading I currently use this:

Code: [Select]

:readmath: binConv(int(value),0,2,1)/10

Negative integers will have all high order bits one, that do not change when transferring them to the modbus commands.

[flash2b]

Ok, that is good news.

For reading I needed the binConv as described above and could not use the /10 in the #scpiCmd.

The format of scpiCmd (or rather the commands) varies with the driver, they are tailored to the protocol.

The dummy port does not work when using #driver Modbus.

That's a pity, will support be added to TestController?

The dummy do not work with binary interfaces at all.
I expect to add that at a later data, but modbus is a bit special and more dedicated support for it would be better. I have not decided about that yet.

I didn't understand why there was a possibility that when I restart the TC maybe the script didn't work.

That was not the issue, but it was impossible to see if it applied the colors without restarting (or using the layout menu to clear the color, but restarting is simpler to say)

Hi HKJ
My electronic payload for the MODE:LIST command returns MODE:LISTxx with the active list file number. Please tell me how to trim or replace this. Or better yet, provide a link to where this is described. I read about "readmach" but couldn't find it...

Readmath is a tag and listen in the list of tags:
https://lygte-info.dk/project/TestControllerConfigDevice%20UK.html#Tags
It also exist with another name for use on #askValues
https://lygte-info.dk/project/TestControllerConfigDevice%20UK.html#mathFormat_&_readmath

If you search for readmath on the above page you will find some examples.

It needs an expression with "value" as the input value and generally this part of the function list is the most useful for it:

I read everything on those links three times, but I'm a bit slow and still don't understand how to do it.

[HKJ]

I read everything on those links three times, but I'm a bit slow and still don't understand how to do it.

A simple way:

:readmath: substring(value,0,9)+substring(value,11)

The first substring returns the part before the number, the second part the part after the number.

[homico]

Thanks...
Well, I'm trying to do something with #askModeMathFormat...🙂

[homico]

It doesn't seem to work here:
#cmdSetup comboboxhot Load__Mode Main_
:read: :FUNC?
:write: :FUNC
:string:
:update: Main_Select
CC CURR
CV VOLT
CP POW
CR RES
OCP OCP
OVP OVP
Dual DUAL
Dynamic DYN
Load Effect EFFECT
List LIST
Auto_List ALIST
LED LED
Timing TIME
Short SHORT
Battery BAT
----------
It works for everyone

[HKJ]

Expressions are exactly the same, there is no difference if you write a expression after:
:readmath:
#askValuesMathFormat
#askModeMathFormat

But the result are used differently

A conditional statement will fix it:

:readformat: substring(value,0,9)=="MODE:LIST"?substring(value,0,9)+substring(value,11):value

You can generally test these expression on the command line, but you have to add a = in front of them:
First you create a value:
=var value="MODE:LIST12"

then you can use the expression:
=substring(value,0,9)=="MODE:LIST"?substring(value,0,9)+substring(value,11):value

Arrow up will recall old commands.

Thank you. Last question: if the File List is not activated, then "xx" appears: how can I exclude them?

[flash2b]

Generally FUNC? should be linked to #askMode (=read) and not the setup menu.

Those functions should be in de mode menu and use #cmdMode instead (=write).

[HKJ]

Thank you. Last question: if the File List is not activated, then "xx" appears: how can I exclude them?

I am not sure what you mean, the substring() do not care about number of x's

[homico]

How do I exclude any/all "x"...?
