5.4.6 Upload Automatically

In the client mode (TCP client, UDP client, MQTT client, HTTP client), the gateway will

automatically poll the instructions stored in the instruction table and upload them to the server. The

feedback format (Modbus RTU format or Modbus TCP format) and the instruction polling interval

(0-65535ms) can be selected according to the requirements.

Instruction prestorage Refer to "Configurable Gateway - Instruction Storage Instructions".

If Modbus TCP is used, you need to enable RTU = TCP conversion.
