Note: When data type is holding register or input register, ToolBox can set different byte orders. Take below Modbus register response from RS485 terminal devices as example:

Register Address

Value (Hex)
0 00 15
1 00 20
2 00 25
3 00 30
When using different byte orders and only one register, you can use ToolBox to fetch different results, and the device will upload data with little endian order.
