Serial Connection with VFD using VISA Write and Read

Hello,

I am attempting to control a Mitsubishi Electric D720 VFD with LabView 2015 using serial communication with an RS485 cable. I started with the simple serial example VI and expanded it from there. Right now I am having trouble with the read function. I get an output of 24 bytes from the write function, but I get a timeout error for the read function. I attached screenshots of the front panel and block diagram to this as well as the VI. If you have any advice or would like me to clarify anything, please let me know.

Thanks,

Marcus
