Hiện tại bên em đang muốn mua 1 số thiết bị cho dự án. Em muốn điều khiển 8 bộ quá trình bằng NI USB 6003. Sau đó liên kết 8 Bộ NI USB 6003 này với 1 bộ PCI 6321 để truyền tín hiệu lên scada. EM muốn hỏi em kết nối như vậy có được không. Và USB có kết nối với NI PCI được không??
Em cảm ơn ạ|

Your setup doesn't make that much sense. Both the PCI-6321 and USB-6003 are multifunction DAQ devices that can acquire a number of channels, output 2 analog outputs and having some digital IO.
Aside from the difference in number of channels and their acquisition speed as well as the connector, they don't really have much of a difference functionally. Since PCI(e) slots are kind of rare nowadays in PCs, the USB variant may be more useful in many situations if you do not require the higher speed of a PCI(e) connected device.
In terms of software you will access both devices through the DAQmx API in almost identical ways, so that should not be a deciding factor.

Is it possible to connect USB to PCI?
No, you cannot connect a USB plug to a PCI slot…
Do you want to emulate serial ports using those USB6003 - or why do you ask those questions?
What is your requirement/task exactly?
