# OPAL-RT Asynchronous Process {#opal}
|
|
|
|
The communication between OPAL-RT models and the S2SS is established by using ansychronous programs.
|
|
Asynchronous programs are are a feature of RT-LAB. They are used to exchange data between Simulink models and custom C programs.
|
|
|
|
For this purpose the C program handels IP/UDP communication via BSD sockets.
|
|
|
|
## Configuration
|
|
|
|
Every `opal` node supports the following special settings:
|
|
|
|
#### `send_id` *(integer)*
|
|
|
|
#### `recv_id` *(integer)*
|
|
|
|
#### `reply` *(boolean)*
|
|
|
|
### Example
|
|
|
|
nodes = {
|
|
opal_node = { # The server can be started as an Asynchronous process
|
|
type = "opal", # from within an OPAL-RT model.
|
|
|
|
### The following settings are specific to the opal node-type!! ###
|
|
|
|
send_id = 1, # It's possible to have multiple send / recv Icons per model
|
|
recv_id = 1, # Specify the ID here.
|
|
reply = true
|
|
}
|
|
}
|
|
|
|
## Arguments for OPAL-RT block
|
|
|
|
RT-LAB already provides a block to establish simple TCP/IP communication: ???
|
|
This block is based on a more generic block used for aynchronous programs: ???
