Receive Data
Usage Scenario
This Step is applicable for custom communication scenarios and is typically used in conjunction with the Parse Data Step or the Data Processing Step for subsequent data analysis and processing.
Workflow
The process of configuring this Step is shown below:
-
Configure and enable the custom communication service to ensure that the communication link is functioning properly.
-
Specify the configured custom communication service in the parameter configuration panel.
-
For TCP server or TCP client-type services, select or disable the Enable Byte Stream Output option based on your requirements.
-
For PLC-type services, specify the relevant register variable.
-
-
Run the step to receive data from the communication service.
| PLC-type services refer to custom communication services of Siemens S7 clients, Modbus TCP slaves, and Mitsubishi MC client types. |
Parameter Description
| Parameter | Description |
|---|---|
Custom communication service |
This parameter specifies a configured custom communication service. |
Register variable |
This parameter specifies the configured register variable. This parameter needs to be specified when the Custom Communication Service is set to a PLC communication service. It is recommended to configure this parameter properly in PLC communication scenarios. Non-PLC communication scenarios may ignore this parameter. |
Enable byte stream output |
This parameter is used to determine whether to output the received data in byte stream format. When enabled, the received data will be output in byte stream format; otherwise, it will be output in the standard data format. This option is unselected by default. If you need to process the underlying data or binary data, you can enable this option; it is recommended to keep it unselected by default for general scenarios. |
