OPAL-RT Asynchronous Process

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: ???

@todo Insert name of RT-LAB blocks.
