First, users must load the electronic device description file (GSD file) of the GW-
7553 into the DP-Master, and then set the parameters. Finally change your DP-
Master from Offline state to Operate state. While DP-Master changes to operate
mode, GW-7553 will initial the modules. Then GW-7553 allocates the memory
space and waits for Set_Prm telegram. The next step is waiting for Check_Cfg
telegram in order. If there is no error occurs, GW-7553 proceeds into data
exchange state. Users can observe the status indicator LED to know the state of
GW-7553. At the meantime, if there is any error occurs, GW-7553 will return to
wait parameterization.
