Specifics¶

The ASAM iLinkRT standard defines a protocol for high-speed measurement and calibration data exchange in test automation systems. From protocol version 3 the standard supports multi-server multi-client environments. So multiple clients can connect to multiple servers to receive data via Ethernet (UDP/P) multicast messages to achieve higher throughput and minimum delay.

Software requirements

iLinkRT server with protocol version 3.0.0

Features

Start and stop measurements manually via tool job or automatically at package start
Access scalar measurements
Start and stop recording
Trace analysis of captured signals if recording format is MDF3 or MDF4 (recommended)

Limitations

No server discovery
Data acquisition only via multicast supported
No page handling
A2L information is not requested from iLinkRT server and has to be configured in ecu.test
No calibration
No access to complex data types (vector, matrix, curve, map)
Measurements are captured in default time raster
Support for one device respectively port at the same time

Notes

The desired capture format can’t be configured in ecu.test tool adapter and has to be set in the tool respectively in the iLinkRT server
Multiclient recording: all clients have to send the STOP command to finish the recording

Info

If the communication between iLinkRT server and ecu.test is working but no measurement is received, please check the firewall settings. The UDP destination port for DAQ frames, that is configured in iLinkRT server should be allowed for inbound connections. If there are multiple network nodes like Ethernet routers and switches between Tool Server and iLinkRT server, check their support for multicast forwarding. If Tool Server and iLinkRT server are running on the same machine it is recommended to not operate the iLinkRT server on the loopback device (“127.0.0.1”) but to use a real network interface instead and configure its true IP address in the test bench configuration.

Properties 🛈¶

Name	Default value	Valid values	Type	Description
iLinkRT server			uri	IP or host name of the iLinkRT server.
iLinkRT server port			int	Port of the iLinkRT server over which commands are sent via Unicast.
iLinkRT client	‘<any>’	[ONLINE]	string	IP address of the iLinkRT client’s network adapter. Using the setting <any> will listen on all network interfaces (corresponds to “0.0.0.0”). The setting <auto> defaults to the computer’s host name with the IP address which it is resolved to. The chosen network adapter is used to receive multicast messages from the server for data acquisition and events. Therefore please make sure this address is reachable by the server, especially if you are using a VPN or proxy.
Start of measurement	Automatically	[Automatically, Manually]	string	Automatically: Automatic start of measurement at test start. At the end of the test the measurement is stopped again. Manually: Start and stop of measurement have to be controlled using tool jobs or directly in the tool.
Timeout for tool call ❲in sec.❳	‘600’		string	Timeout after which a tool call is aborted.
