Command forwarder closes TCP connection on first command after reboot.

[Myles Metzler]

The Command forwarder feature will close the TCP connection the first time it receives a command. It works correctly after that first connection.

This has to do with the configuration database session being created at start up before the database is ready. After the bad session is closed and a new one is established the problem goes away.

I am trying to communicate with the Espec PR-3J chamber with controller ID P3PLJCN30.03STD. I am using National Instruments LabVIEW version 2018 and communicating via NI VISA protocol and also NI TCPIP protocol (I tried both methods). I issued the command MON?\r\n once, and can read back the measured temperature and humidity. If I issue the command again (ie. 2nd time), the NI VISA or TCPIP protocol will error out on the read command. Is this error that I am getting related to this issue #96? Just wanted to ensure that I am understanding this issue correctly. FYI, I am using the following resource name on LabVIEW: "TCPIP0::172.16.5.4::57732::SOCKET". Thanks.

Oh yes, one more thing, I understand that there is another method of interfacing via the REST API. I have attached the screen capture of the Espec web-access on the "Chamber Setup" page. Where is the option to enable the REST API? Thanks.

The Espec Corp Japan and Espec North America produced chamber's do not currently have the same software (we plan to fix that but that does not help you now).

The best way for you to to currently get assistance with that model of chamber is to contact Espec Corps service department here: https://www.espec.co.jp/english/inquiry/customer-oversea.php

Myles, thank you for pointing me to the right direction.
