Component: Network Communications Dummy (Comms: Networking)
| Author | Matrix TSL |
| Version | 1.1 |
| Category | Comms: Networking |
Network Communications Dummy component
A component designed to simplify the process of TCP/IP communications. Compatible with most of the Flowcode supported TCP/IP and WIFI components. A useful building block for creating components such as IoT and Modbus TCP.

Examples
Here are some examples showing the Network Communications component in action.
By itself the component provides a generic TCP/IP layer to drive the simulation runtime.
Here is a simple example showing the component used by itself to request data from a remote server on the internet.
Library Components
Components such as Webserver (GENERIC), MQTT and Modbus TCP can connect to and control the network comms layer.
Here is a simple example showing the component used with the Webserver (GENERIC) component.
Example Network Comms Web Server
Embedded Components
The Network Communications component can also be connected to embedded TCP/IP and WIFI style modules allowing for the abstraction to work with specific networking hardware modules.
Here is the current status of the Network Communications component with the various embedded modules.
| Embedded Component | Other Variants of Component | Support Status |
|---|---|---|
| TCP/IP (Raspberry Pi) | N/A | Fully Supported |
| WLAN (ESP8266) | WLAN (ESP-12S), WIFI (BL0136), WIFI (ESP8266) | Fully Supported |
| TCP/IP (W5500) | N/A | Fully Supported |
| ENC28J60 | N/A | On Hold |
| TCP/IP (NM7010A) | TCP/IP (EB023v1) | On Hold |
| TCP/IP (W5100) | TCP/IP (EB023v2), TCP/IP (WIZ810MJ) | On Hold |
| WLAN (WIZ610WI) | WIFI (EB069) | On Hold |
We are working through and adding support as and when we get chance so if you have a module that isn't listed or would like to try and prioritise a specific module then you can let us know via the user forums.
Macro reference
|
Connect |
| Connects to an IP address as a client on the specified port. Some TCP/IP modules (RPI and ESP8266) will accept a URL instead of an IP address. Returns: 0=Fail, 1=OK | |
 - STRING
|
Address |
| IP address as a string e.g. "192.168.1.1" or URL on some TCP/IP modules | |
 - UINT
|
Port |
 - BOOL
|
Return |
|
|
Receive |
| Attempts to receive up to a specified number of bytes from the active connection. Returns the number of bytes received. | |
| - STRING
|
Data |
| - UINT
|
Count |
| Maximum number of bytes to read | |
| - UINT
