7.10.2.6 Setting IEC103 Parameters

Third-party devices that use the IEC103 interface protocol may be connected to PV plants.
The SmartLogger can read the information about such third-party devices and upload the
information to the NMS, enhancing the PV plant solution.
As Huawei inverter devices (such as SUN2000s) support protocols different from third-party
devices that use standard IEC103 (such as box-type transformers, combiner boxes, and
inverters), they cannot be connected in series on the same RS485 bus.


Modbus TCP is a general standard protocol without a security authentication mechanism. To reduce
network security risks, the function of connecting to a third-party NMS using Modbus TCP is
disabled by default. To use this function, set Link setting to Enable(Limited) or
Enable(Unlimited). If you select Enable(Limited), the SmartLogger can communicate with up to
five third-party NMSs whose IP addresses are set under Modbus TCP. If you select
Enable(Unlimited), the SmartLogger can communicate with all third-party NMSs with valid IP
addresses.

If the function of connecting to a third-party NMS using Modbus TCP is enabled, data will be
transmitted without being encrypted, which may result in user data theft. Therefore, exercise caution
when deciding to enable this function.
 In most cases, set Address mode to Comm. Address. If the devices connected to the COM ports of
the SmartLogger have duplicate communications addresses, you must set Address mode to Logical
address.
