4.7 Connecting the Box-type Transformer

Context
The SmartLogger can be connected to a box-type transformer over the RS485 and Ethernet
communication modes.
This section describes how to connect a box-type transformer that supports the Modbus-RTU
or IEC103 protocol to the SmartLogger using the RS485 communication mode.
Devices from different vendors may support different protocols. To obtain information from
the connected box-type transformer, correctly configure the protocol on the WebUI of the
SmartLogger based on the document delivered by the vendor.
For the definition of the RS485 communications cable for the box-type transformer, see the
delivered operation guide.
There are six RS485 ports in the SmartLogger. For the port descriptions, see Context in
Connecting the SUN2000 Using an RS485 Communications Cable of 4.4.1 Connecting the
SUN2000.
Figure 4-28 shows how to connect the SmartLogger to the box-type transformer through an
RS485 signal SPD.

After connecting the cable for a power meter that supports the Modbus-RTU protocol, log in to the

WebUI and set parameters under Modbus Power Meter. For details, see Setting Power Meter
Parameters.
The communications protocol configured for devices connected to the same SmartLogger COM port

must be the same. After connecting the cable, log in to the WebUI and modify the COM port
protocol. For details, see Setting RS485 Parameters.
A power meter cannot be detected automatically. You need to add this device manually. For details,

see Connecting a Device.
After modifying the protocol for a DL/T645 power meter and adding it manually, log in to the

WebUI to query and set parameters under DL/T645 Power Meter.
----End
The SmartLogger provides two Ethernet electrical ports. A box-type transformer that supports Ethernet
communication can be connected to the SmartLogger through an Ethernet electrical port, and then to an
NMS through the northbound interface of the SmartLogger. In this connection mode, the IP addresses of
the SmartLogger and the box-type transformer must be in the same network segment.
