PLC Data acquisition protocol conversion gateway
-D225
Operation instructions: (1) After logging in to the device that needs to be configured (in this
example, double-click the IP address: 192.168.1.250 to log in), select the device protocol, whether
it is an electricity meter with DL/T645-1997 or DL/T645-2007 protocol, select The device protocol
is DL/T645 protocol, (2) Because the D225 device and the meter are connected through RS485, so
choose the serial port 2 (485), (3) This example takes Modbus TCP Server protocol as an example,
so choose Modbus TCP Server The default number is "502" or you can modify it according to your
needs. If you want to send data to the cloud platform, you can choose our company’s Jin Geyun
2.0 or Jin Geyun 3.0 or Modbus RTU Over TCP. (4) Select RS485 for the serial port. The configuration
information is configured according to the meter RS485 port parameters. (5) D225 device You can
choose to automatically obtain the IP address settings or specify the IP address according to your
own needs. (6) After configuring the configuration information, click "Save parameters", (7) Click
"Save parameters", and click "Restart" or The D225 device is powered off, power on and restarted,
and the modified configuration can take effect.
5.3.2
Use Modbus Poll tool to simulate the system to collect data
from three-phase multi-function meters
Modbus Poll tool is a very useful Modbus debugging tool, which can be downloaded from the
Internet.
Take the A-phase, B-phase, and C-phase voltage of the electric meter, the communication address
of the electric meter is “000000000000”as an example, the corresponding D225 mapping address
is: 50-52, and the specific mapping address corresponding to D225 is shown in
address corresponding to three-phase multi-function meter
