Setting MBUS Parameters

Procedure

1. Set access parameters.
   • Set parameters for the built-in MBUS and click Submit.
   Figure 6-15 Setting parameters for the built-in MBUS
   

   Parameter	Description
   Built-in MBUS	If the SmartLogger communicates with the solar inverter using a built-in MBUS, set this parameter to Enable. If only RS485 communication is used between the SmartLogger and the solar inverter and third-party device, set this parameter to Disable.
   Device disconnection time	Specifies the duration for determining device disconnection.

   • Set access parameters for an external MBUS.
     • Method 1: Click Auto. Search to connect the MBUS.
     • Method 2: Click Add Devices, set access parameters, and click Add Devices.

   Parameter	Description
   Device type	Set this parameter to MBUS.
   Port number	Set this parameter to the serial number of the COM port connected to the MBUS.

2. Set networking parameters.

   Category	Parameter	Description
   Running Param.	Baud rate	Retain the default value 115200 for optimal communications performance.
   	Anti-crosstalk	Set this parameter to Enable. When the transformer substation number and winding number of the solar inverter are the same as those of the MBUS, or the solar inverter SN is in the SN list, the solar inverter can connect to the SmartLogger over an MBUS network.
   	Network frequency band	Set this parameter as required.
   	Box-type transformer No.	Set this parameter based on the number of the transformer substation connected to the SmartLogger.
   	Winding No.	In multi-split transformer substation scenarios, set this parameter based on the number of the winding of the transformer station connected to the SmartLogger.
   	Networking	When the SmartLogger communicates with the solar inverter over MBUS, set Networking to Enable. When the SmartLogger communicates with the solar inverter only over RS485, set Networking to Disable.
   SN List	N/A	Maintain the solar inverter SN list. You can click Synchronize to synchronize the transformer substation number and winding number of the MBUS to the solar inverters in the SN list.
