Network Communications 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.

Detailed description

No detailed description exists yet for this component

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.

FC6 Icon.png Example Network Comms Client


Library Components

Components such as Webserver (GENERIC), MQTT and Modbus TCP can connect to and control the network comms layer.

NetComms1.jpg


Here is a simple example showing the component used with the Webserver (GENERIC) component.

FC6 Icon.png 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.

NetComms2.jpg


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.
