Serial Modbus RTU Timeout Error

Hello,

 

I have problem with communication with Mitsubishi Electric 96NSR via Modbus RTU. Device has RS485-USB converter. I tested connection in MAX. I can write, but when I try to read, I encounter Timeout Error (Hex 0xBFFF0015). Could anyone help me with my problem? I use Labview 2015 (32 bit)/ Windows 10

 

MAX Settings:
Baud rate: 38400

Parity: none

Flow control: none

Data bits: 8

Stop bits: 2

Timeout: 2000 ms ( I tried also 10000ms )

 

PS. I checked the connection with Modbus Poll with same settings and it worked fine.
