AD Power M2M4 Meter communication driver’s read schedule
Read schedule setting parameters are as follows:
1) STATION – 0 ~ 999 equipment ID address.
2) Read command – Command = DATA.(Refer to <Table 1>)
3) Read Start Address – Don't care.
4) Save Start Address for Communication Server – Saving start address of Communication Server.
5) Read Size – Size = Fix to 1.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> will be shown.
You can change Power Meter ID by using write commands.
Bit write
Bit write and word write have the same setting parameters except output value(0 or 1).
Word write
Word write setting parameters are as follows:
1) PORT : Port no. (0 ~ 255)
2) STATION : 0 ~ 999 equipment ID address.
3) ADDRESS : Don't care.
4) EXTRA 1 : Write command = CI (change Power Meter ID command).
5) EXTRA 2 : Don't care.
Write example 1)
PORT:0, station:1, ADDRESS:0000, Extra1:CI, Extra : 0
The setting parameter shown above is an example of write for changing ID(1 ~ 999) of AD Power Meter connected with 0 port and 1 equipment ID.
Note) CI write command use at 1:1 connection. If you connected 1:N, it will set equal ID(all connected equipment).
Block write
AD Power M2M4 Meter communication driver don’t support ‘Block write’.
