Injector (Flowcode vNet) component
Comms data injector to allow components to talk to each other between instances of Flowcode. The injector allows the data to be sent and received between multiple instances of Flowcode either running on a single machine, across a network or via the internet.

Examples
Simple Single Instance
Sends out data and prints incoming data to an LCD. Uses the same port number for transmit and receive.
Simple Multi Instance
The first program sends out data.
The second program receives the data and prints to an LCD.
Remote Lock
Here is an example of using the vNet injector to simulate a multi microcontroller system.
Microcontroller 1 is connected to a keypad and has a RS232 communications connection.
Microcontroller 2 is connected to a solenoid and has a RS232 communications connection.
Any key presses detected on microcontroller 1 will be sent via RS232 to microcontroller 2. If the correct byte sequence (1234) is received by microcontroller 2 then the solenoid is fired to unlock a door for 5 seconds.
Communications over the vNet injector can be monitored using the console.
Modbus Master and Slave example using vNet
Example of communicating using Modbus Master and Slave using two instances of Flowcode and the vNet injector component.

vNet Injector Settings |
|
Network Interface |
| Allows different network interfaces to be selected. The current network interface can be determined by looking at the My IP properties. | |
|
|
Incoming Channel |
| TCP Channel Instance, allows multiple servers and clients to run on the same machine or inside the same simulation. | |
|
Incoming Port |
| Port used for incoming communications. 80=HTTP Ports have to match up to allow communications to be sent and received. | |
|
|
Outgoing Channel |
| TCP Channel Instance, allows multiple servers and clients to run on the same machine or inside the same simulation. | |
|
|
Outgoing Port |
| Port used for outgoing communications. 80=HTTP Ports have to match up to allow communications to be sent and received. | |
|
|
Connection Mode |
| Specified if this Vnet node is going to connect to another instance of Flowcode running on this PC or a networked PC. | |
|
|
Circular Buffer Size |
| Size of the circular buffers used to temporarily store the incoming and outgoing data. | |
