4.4.4 Input calibration

[Note] If there is no professional calibration equipment, it is not recommended to calibrate, otherwise, the
error of analog acquisition will become larger, and the calibration method needs to be requested from customer
service.

4.5 Modbus gateway

The device can convert non-native Modbus commands to data (interconvert Modbus TCP and Modbus RTU
protocols) and then transmit them. In theory, it can process 128 slave addresses at the same time (restricted by the
serial port access device).

4.6 Active upload

The device supports the function of uploading analog input values at fixed time intervals. Setting the value of
the corresponding register can control the interval time and whether to upload or not.
The device with digital input will actively upload once after connecting to the server successfully, and then the
digital input will be uploaded following the status change, and the device with analog input will report the status of
the analog input according to the configuration of the active upload time period (the configuration period is
1-65535 ).
When set to 0, the upload is closed, and when set to another positive integer value N, the upload is performed
at intervals of N seconds.
[Note] The device can only be valid if it is in the client mode configuration. If the register value is non-zero,
active uploading is enabled.

4.7 Custom Module Information
