This is all you need to do. Besides setting up de comm parameters

Hi friends, im new here, so sorry to use a existent topic to make my question, but is one similar question!

Im using one FX5U(modbus master) built in 485 port the communicate with 1 level transmiter, 2 flow transmiters and 5 Inversors.

Im trying to use ADPRW multiple times, following the information in  FX5 User's Manual (MODBUS Communication)

Until now i only use the simulator to test, but my function ADPRW never give me some feedback like timeout or fail. Do you know if this kind 

of functions work only with physical controller(FX5U)? 

i will send some pictures attached here for you help me and say if im doing something wrong
