<Figure 1>  Read setting example of HPR-MD MODBUS communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(19200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.

Note) Station number, baud rate, etc of HPR-MD power meter can set by using operation button of front panel.

HPR-MD MODBUS communication driver read schedule

Read schedule setting parameters are as follows:

1) Station – 0 ~ 255 station number of power meter.(you can set by using operation button of fron panel)

2) Device name of function number – Device name or function number of Modbus protocol.

Device name = DATA, EVENT1 ~ 3, FAULT1 ~ 3, RELAY, WAVE, INPUT. ( refetr to <Table 1>)

3) Read Start Address – Reading start address of modbus protocol. Don't care when using Device name.

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read Size – Read size(Word unit).

Read schedule example)

READ,    1,  DATA,     0,    0,  36,

READ,    1, RELAY,     0,   50,   1,

READ,    1, INPUT,     0,  100,   1,

READ,    1,  WAVE,     0,  150,   1,

<Table 1> is device type and contents of HPR-MD MODBUS communication driver.

<Table 2>, <Table 3> are data saving address and contetns of basic Data, Event record.

<Table 4>, <Table 5> are data saving address and contetns of Fault record, Relay Setting status.

<Table 6>, <Table 7> are data saving address and contetns of Header information and Fault wave Data, Digital Input status.

 If you click the icon  in protocol option part, you can see the dialogue box such as <Figure 2>. you can also set read schedule by using this part.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.

2. Writing settings

You can set HPR-MD controller by using write settings.

Digital Write

Digital write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION              0 ~ 255 station number of HPR-MD controller.

3)  ADDRESS           Writing address according to Extra1.

RELAY – 0 ~ 25 address, refer to <Table 8>,

TIME – 0 ~ 23 = hour,

DATE – 0 ~ 99 = year,

Read Command  – Data saving address(WORD memory, decimal unit),

other command – don't care.(fixed according to command),

4)  Extra1                   Write command.

RELAY – Relay setting,

CT – CT Ratio setting (5 ~ 6000),

GPT– GPT Ratio setting (199 ~ 999),

PTT – PT Type setting ( 0 : 2PT, 1 : 3PT),

PT – PT Ratio setting ( 110 ~ 345000 ),

CB – CB ON/OFF control (0 : OFF, 1 : ON,  can control only Remote mode),

TIME – time setting,

DATE- data setting,

RESET- Reset of power,

REMOTE- Local/Remote setting (0 : Local, 1 : Remote)

DATA, EVENT1~3, FAULT1~3, RELAY, WAVE, INPUT read command - save to WORD memory from input 'Address' after reading the data.

5)  Extra2                   Minute or day of the week when TIME, DATE command.

TIME – minute (0 ~ 59),

DATE – day of the week (1(sunday) ~ 7(saturday),

Read command or other command - Don't care.
