Lab 5: Send sine wave to simulator
We can combine the villas signal and villas pipe tools to send a sine wave to a node.
In this lab, the node is a RTDS GTNETv2 card running the SKT firmware.
We use a slightly modified configuration file in order to change the UDP packet format:
node/etc/labs/lab5.conf
nodes = {
rtds_gtnet1 = {
type = "socket"
layer = "udp"
format = "gtnet"
in = {
address = "*:12000"
signals = {
count = 8
type = "float"
}
}
out = {
address = "134.130.169.89:12000"
}
}
}
villas signal -v 4 -r 1000 mixed | villas pipe lab5.conf rtds_gtnet1
villas signal -f 50 -r 10000 sine | villas pipe lab5.conf rtds_gtnet1
As we can see in the diagram, the villas pipe tool also receives data which is sent by the simulator and prints it to the screen.
