Connect PT104 to more computers via ethernet

Post by luca.pessini »

I need to create a system with 8 data loggers PT-104 connected via ethernet.
I have to constantly and simultaneously interrogate the data loggers from 2/3 computers.
When the first computer opens communication with data loggers, sends the command LOCK and does not allow other computers to connect.
Can I program the data loggers so they can communicate in broadcast?
Are there any alternatives?

Thank you.

Hi Luca,

The connection to the device from the PC is UDP. However, only one application can access the device at a time due to the way the dll works.

Perhaps you can configure the application on the PC that is connected to the device to act as a server and accept requests from the other 2 PCs to interrogate the device.

Which programming language are you using?

Best wishes,

Thanks for the reply.
The development environment that I use is LabWindows CVI ... basically the C language
I want to create a redundant system. If a computer were to break, the other computer will continue to collect and record data (without interruption).
If I knew the communication protocol, I could communicate directly and avoid using the DLL.

Hi Luca,

I'm afraid communication with the device is only via the dll.

Best wishes,
