4.8 Connecting a 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 standard
Modbus-RTU or standard IEC103 protocol to the SmartLogger using the RS485
communication mode.
Devices from different vendors may support different protocol specifications. To obtain
information from the connected box-type transformer, correctly configure the protocol
specifications on the WebUI of the SmartLogger based on the protocol specifications
delivered by the vendor.
For the definition of the RS485 communications cable for the box-type transformer, see the
delivered operation guide.
The SmartLogger provides six RS485 communications ports. For the port descriptions, see


After connecting cables to the power meter that supports Modbus-RTU, log in to the embedded
WebUI and set parameters for Modbus Meter. For details, see
Parameters.
 Devices connected to a same COM port of the SmartLogger must support the same protocol. After
connecting cables, log in to the embedded WebUI and modify the COM port protocol. For details,
see 7.10.2.2 Setting RS485

A power meter cannot be detected automatically. You need to add this device manually. For details,
see 7.11.8.1 Connecting
supported by the connected power meter.
 After modifying the protocol for a DL/T645 power meter and adding it manually, log in to the
embedded WebUI to query and set parameters for DL/T645 Meter. For details, see
Meter.
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.
