Typhoon HIL Ethernet VE

VILLASnode can interface with Typhoon HIL simulators via their Ethernet Variable Exchange protocol. On VILLASnode's side this interconnection is realized with the socket node-type and the raw format-type.

Tested Versions

The setup covered on this page has been tested with the following software versions:

Typhoon HIL Control Center: 2022.1
VILLASnode: Commit 634d95362a7e776cc8d6b5999bc5c5e83be15870

Limitations

Only the UDP protocol is supported by VILLASnode
Sending and receiving of string values is not supported by VILLASnode
All exchanged signals must use the same number of bytes
- But data-types can be different for each signal

Typhoon example model

VILLASnode ships with an example schematic for the Typhoon HIL control center.

Settings

In this demonstration we use the following settings as an example:

Setting	Value
IP Address of Typhoon HIL target	`192.168.2.100`
IP Address of VILLASnode	`192.168.2.200`
Subnet Mask	`255.255.255.0`
UDP Port Number on both sides	`12000`
Number of bytes per signal	`8` (64 bit)
Endianess	Little

Configuration

VILLASnode

This VILLASnode configuration configures a simple loopback of the data send by the Typhoon HIL target back to itself.

typhoon.conf
stats = 1.0

nodes = {
    typhoon_1 = {
        type = "socket"
        layer = "udp"
        format = {
            type = "raw"
            endianess = "little"
            bits = 64
        }

        in = {
            address = "*:12000"

            hooks = (
                "stats"
            )

            signals = (
                { name = "signal0", type="float" },
                { name = "signal1", type="integer" },
                { name = "signal2", type="boolean" },
                { name = "signal3", type="float" },
                { name = "signal4", type="complex" }
            )
        }

        out = {
            address = "192.168.2.100:12000" # IP Address of Typhoon HIL target
        }
    }
}

paths = (
    {
        # A simple loopback
        in = "typhoon_1"
        out = "typhoon_1"
    }
)

Signal configuration

You can either configure the signal mapping via Typhoon graphical editor as shown in the screenshot below:

Or alternatively you can copy the following signal configuration into the Configuration property:

Signal type mapping

VILLAS signal type	Typhoon-HIL signal type
`boolean`	`uint`
`float`	`real`
`integer`	`int`
`complex`	use two consecutive `real` signals
