7.9.2.6 Setting IEC103 Parameters

Third-party devices that use the IEC103 interface protocol may be connected to a PV plant.
The SmartLogger can read the information about such third-party devices and upload the
information to the NetEco, thereby enhancing the PV plant solutions.
As Huawei inverter devices (such as SUN2000s) support protocols different from third-party
devices that use IEC103 (such as box-type transformers, combiner boxes, and inverters), they
cannot be connected in series on the same RS485 bus.
If the SmartLogger connects to the NetEco, it transparently transmits IEC103 device
information to the NetEco.
Because of permission restriction, log in as Advanced User. Choose Settings > IEC103 to
access the target page.

 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.
 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, Address mode is set to Physical address. If the devices connected to the six RS485
ports of the SmartLogger have duplicate addresses, you must set Address mode to Logical address.
