Communication profibus with MM300

Hello;

I have a Profibus communication with a MM300 which I have a problem with the motor control according to the exchange table I have  a control word where I have to write 74 to enter the remote mode and 75 for manual mode. The running order is writing the value 8 and the stop is the 4. But  I must use a BFI block. the problem is I can not seem to write the estimate because 4 he will find 74 of the remote mode by adding 4 it gives 78 .

Thank you for your help.

Best regards.

Butler faith.
