Hi everyone, i am following a project in the company where we have a Schneider Power Meter model iem 2155 and it is connected via usb/rs485 to a pc, I wanted to know if you know a "universal" project to see the measurement of the Power Meter on Labview. Thanks everyone in advance.

A quick search results:
You can communicate with this device over Modbus or M-Bus:
You can use LabView Libraries to communicate over Modbus: NI Modbus
For M-Bus you must make self research:

so you think it is impossible to read the data by connecting the Power Meter with VISA driver then COM port using the usb port.

You need Adapter USB to Modbus RTU (which is RS485).
The USB Adapter should install a virtual COM Port (e.g. COM05). This virtual COM Port you can use in NI VISA to send data to it and read data from it.
In the NI Modbus you then select Modbus RTU and pass the COM Port.
