Description

This Step sends data to a custom communication service.

Usage Scenario

This Step is primarily intended for scenarios that require real-time data transmission to custom communication services, including external communication systems, PLCs, and servers. This Step can be connected to upstream Steps such as a data processing Step or the Assemble Data Step.

Workflow

The process of configuring this Step is shown below:

Select the data to be sent as input.
Set the custom communication service to specify the target communication service.
- For communication services of the TCP server or TCP client-type, select or disable the Send data as byte stream option needed.
- For PLC-type communication services, also configure the register variable parameters.
Run the Step, and the data will be sent to the target communication service.

PLC-type services refer to custom communication services of Siemens S7 clients, Modbus TCP slaves, and Mitsubishi MC client types.

Input Description

The input is the data to be sent. The input data will be sent to the specified custom communication service.

Parameter Description

Parameter	Description
Custom communication service	This parameter specifies the configured custom communication service as the data transmission destination. It is recommended to select a correctly configured communication service based on the actual communication requirements.
Send data in byte stream	When enabled, the data is sent in byte stream format; when disabled, the data is sent in string format. This parameter is only applicable when the custom communication service is set to TCP server or TCP client. Unchecked by default. Enable this option if the destination communication service expects data in byte stream format; otherwise, leave it deselected.
Register variables	This parameter specifies the configured register variables. This parameter is only applicable when Custom Communication Service is set to PLC type. If the destination communication service is of the PLC type, Register variables must be specified; otherwise, communication will fail.

Parameter

Description

Custom communication service

This parameter specifies the configured custom communication service as the data transmission destination.

It is recommended to select a correctly configured communication service based on the actual communication requirements.

Send data in byte stream

When enabled, the data is sent in byte stream format; when disabled, the data is sent in string format. This parameter is only applicable when the custom communication service is set to TCP server or TCP client.

Unchecked by default.

Enable this option if the destination communication service expects data in byte stream format; otherwise, leave it deselected.

This parameter specifies the configured register variables. This parameter is only applicable when Custom Communication Service is set to PLC type.

If the destination communication service is of the PLC type, Register variables must be specified; otherwise, communication will fail.

Output Description

This Step has no output items.
