I am unable to control an Danfoss inverter VLT 2800 via profibus using Siemens S7300 PLC.
Communication between PLC & VLT 2800 is established using Type PPO 3(I/O address 256).

I programmed as follows

L W#16#047E
T PQW 256
L W#16#4000
T PQW 258

But the inverter is not getting start commands.

Kindly guide

16#047F enables the drive - bit 0 on
16#047E stops the drive - bit 0 off

What do you read in the status word from the drive?
You must decipher the hex code and relate it to the individual status bits.

Dear sir,
As per your request, I have attached here the print screen of HW and LAd design.
I hope you will check and advise me, how I progress my learning about VLT2800 with S7 300.
I don't understand the program
If you want my sample program more undersigning I will send you.
For your kind information program file size is more than 5MB so it need send through email.
