KILO Power Meter communication driver

KILO Power Meter communication driver is the driver to communicate with power meter(Three-phase energy analyzer and controller) of ELECTREX in Italy.

1. Read Settings

<Figure 1> is read setting example of KILO Power Meter communication driver.

<Figure 1>  Read setting example of KILO Power Meter communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(2) respectively, according to controller.

KILO Power Meter communication driver read schedule 

Read schedule setting parameters are as follows:

1) Station – 0 ~ 255 controller station number.

2) Modbus function number – Function number = 2, 3, 4, 7, 17.

3) Read start address –  Reading start address of modbus. ( from 1 ~ )

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

5) Read Size – Read size. 1 ~ 8, function 2, 7, 17 = fixed to 1. 

6) Read Byte count – Number of Byte. ( refer to <Table 2> ~ <Table 4> )

Note) KILO Power Meter communication basically equal Modbus protocol.

2. Writing settings

 You can write the setting value  by using 'writing settings'. 

Digital Write

Digital write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             0 ~ 255 controller station number.

3)  ADDRESS          Writing modbus address. (0 ~ 13, refer to <Table 4>)

4)  Extra1                  Don't care.

5) Extra2                   Don't care.

Write example 1)

PORT:0,  station:1, ADDRESS:0010, Extra1:  ,  Extra2 : 0

The setting parameter shown above is setting example for on/off relay 1.

Analog Write 

Analog write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             0 ~ 255 controller station number.

3)  ADDRESS          Writing modbus address. (0 ~ 8, refer to <Table 5>)

4)  Extra1                  Don't care.

5) Extra2                   Don't care.

Write example 1)

PORT:0,  station:1, ADDRESS:0005, Extra1:  ,  Extra2 : 0

The setting parameter shown above is second and minute of current time setting example.
