Register address
The address of the register from which data will be read.
Data type
Defines how read data will be stored. See
Response timeout
If the Modbus device does not receive a response within the time specified here, the communication
times out. Valid settings are from 10 – 65535ms.
Data report
The trigger of reporting data. Valid values:
On Change: The report is triggered if the collected data changes. You can use a tolerance to only log
the data point if the value changes more than X amount.
Interval: Collect the variable data at the poll interval and report the data at the specified report interval.
Timer: Collect the variable data at the poll interval and report the data at the regular time.
Register address mapping
This function is usually combined with modbus address mapping to realize a single modbus command
query in data query.
Formula
Modbus register store only whole numbers. For this reason a scale factor often needs to be applied.
For example a modbus register with a temperature value may read as 723 and a multiplier of 0.1 need
to be applied to get the correct value of 72.3 in the SCADA system,the formula is %s*0.1. If the data
type is a Float then the multiplier is not needed. This computation su, -, * and / operators.

Parameter Item
Description
Communication channel
Select the channel in the socket type. You can choose TCP/UDP or HTTP in socket A of each serial
port, or MQTT you have added.
Data query
Query type. You can choose Modbus RTU, Modbus TCP or JSON. Users can send the right format
query command from remote modbus master or MQTT publisher to the N5X0 gateway. The data is
retrieved from the device's cache of corresponding modbus instructions.
Data report
The trigger of reporting data. Valid values:
