ZMD405 Meter(Landis+Gyr) communication driver read schedule

Read schedule setting parameters are as follows:

1) STATION – Equipment ID = 0 ~ 255.

2) Read Command – Command = INI, DATA.(Refer to <Table 1>)

3) Read Start Addres – INI Command = 0 ~ 255 : INI Data File Number,

DATA = 0000h ~ FFFFh(65535) : Data Address.

4) Save Start Address for Communication Server – saveing start address of Communication Server.

5) Read Size – read size = 1.
