Tektronix PWS4323 VISA Remote Control: VI_ERROR_TMO on Query Commands

Hey there, i will be glad to find someone who could help me solve a problem connected with “remote controlling power supply throw visa”
I have power supply Tektronix PWS4323 and wanna establish remote connection using visa library commands. After connection to a host next stages were finished successfully:
define device by the host
add file device usbtmc
opening session by call viOpenDefaultRM
connection with device viOpen

An the same time requests without reply go on well (like "*RST", "VOLTAGE 3V", "SYSTEM:REMOTE" ....) and finish with the status VI_SUCCESS. Transmissions execute by the command viWrite, and write and read operations to registers end without mistakes.
However command needing reply on a request often finishes with mistake VI_ERROR_TMO (viBufRead or viScanf) Why I write “often” instead of “always”, because sometimes it finishes successfully but I couldn't find clear dependence on such behavior. For example there're exist commands like *ESR?, *TST? Returning a short answer in a few symbols. If i use an additional delay after each operation writing then reading could finish successfully too, but *IDN? always finishes with an error

What could be reason for such behavior. Honestly I have already wasted two weeks and almost give up to find solution.
Additional info:
OS – LINUX, setting a visa library were going through deb packets libivivisa0_7.0.0-0_x86_64.deb, libivivisa0-devel_7.0.0-0_x86_64.deb, libivivisa-confmgr0_7.0.0-0_x86_64.deb, libivivisa-confmgr0_7.0.0-0_x86_64.deb, libivivisa-utilities0_7.0.0-0_x86_64.deb
After the end of connection I have tried set some addition attributes to setup session VI_ATTR_TMO_VALUE, VI_ATTR_TERMCHAR, VI_ATTR_TERMCHAR_EN, VI_ATTR_SEND_END_EN

could you provide more about this

Have you resolved this?

It sounds like you are experiencing a timeout error when trying to read from the power supply using the VISA library. This error can occur if the device is not responding to the read request within the specified timeout period.

There are a few things you can try to troubleshoot this issue:

1. Check the documentation for the power supply to ensure that you are using the correct commands and formatting for requests that expect a reply.

2. Try increasing the timeout value using the VI_ATTR_TMO_VALUE attribute. This attribute allows you to specify the maximum time the VISA library should wait for a response before timing out.

3. Check the cable and connection between the computer and the power supply to ensure that it is functioning properly.

4. Check the power supply itself to ensure that it is functioning properly and is not experiencing any issues that could prevent it from responding to requests.

5. If you are using a USB-to-GPIB adapter, ensure that it is configured properly and working correctly.

I hope this information helps. Let me know if you have any other questions or if there is anything else I can do to help.
