DISTRIBUTED DATA LOGGING

With the CCA 9010 and CCA 7010 data loggers, you benefit from the decisive advantages of state-of-the-art Distributed Data Logging Systems:
 

  • FLEXIBILITY
  • SCALABILITY
  • RELIABILITY


In order to record automotive interfaces such as CAN-FD, FlexRay, LIN or Ethernet (10Base-T1S, 100Base-T1 or 1000Base-T1) as well as proprietary camera interfaces such as FPD-Link III or GSML2, external Capture Modules (also called measurement adapters) are connected to the central ViGEM data logger. These Capture Modules convert the incoming data and forward it to the data logger via robust Ethernet connections.

The ViGEM data loggers offer up to 40 standard Ethernet interfaces (1000Base-T and SFP+/SFP28) with up to 25 Gbit/s:

  • for the connection of Capture Modules
  • for the direct connection of control units, measurement PCs 
  • for the cascading of further loggers. 

Benefit from numerous advantages

PERFORMANCE by ViGEM

Flexibility And Security of Investment

Requirements can change!
Due to the decentralized concept and the support for the ASAM CMP standard, the data logging system of ViGEM can be quickly adapted to new requirements. This also applies to future sensors and on-board networks. It is easily possible to add or replace additional Capture Modules afterwards. In order to multiply the performance, it is possible to cascade and synchronize several data loggers.

   Your investment is secured even in the event of changing framework conditions and across several projects! 

High-Precision Time Stamping

The time base of all system components is synchronized via Ethernet and the Precision Time Protocol (IEEE 802.1AS or IEEE 1588-2008). The data to be recorded is already tagged with a highly accurate common time stamp in the Capture Module, packaged in Ethernet, sent to the logger and recorded there. The CCA data logger can be time master or can pass on the time of an external master as boundary clock to connected modules.

Point-to-Point Connections

Most of the high-speed connections in a vehicle, such as GSML2 or 1000Base-T1 Ethernet, are point-to-point connections. These connections must be cut to capture the communication. By using a Capture Module, the outbound and return lines do not have to be routed all the way to the data logger. The original connection can be closed quickly regardless of the derivation to the data logger, the influence of the test vehicle is minimized.

Signal Integrity

With CAN-FD or FlexRay, signal interference can occur due to stub lines and the extension of lines to a central data logger. The Distributed Data Logging concept allows the measurement adapters to be placed close to the signal source and the lines to be kept short.

Convenient Usage

Configuration access to Capture Modules via the ViGEM data logger.

COMPATIBILITY

  • Time synchronization according to IEEE 802.1AS (gPTP) or IEEE 1588-2008 (1588 V2)
  • Connection of Capture Modules or measurement adapters via PLP, TECMP or the new ASAM CMP standard
  • Direct connection of control units, lidar or interface modules via Ethernet-RAW, UDP, TCP, XCP-over-TCP
  • For recording CAN, CAN-FD, FlexRay, LIN, 10Base-T1S, 100Base-T1, 1000Base-T1 we recommend the Capture Modules of the company Technica Engineering. The connection of further Capture Modules is possible.
  • For recording FPD-Link III or GSML2 we recommend the SerDes logging adapters of the company AED Vantage. The connection of further Capture Modules is possible.
  • Proven compatibility: The interaction of CCA data loggers and Capture Modules is constantly tested in the ViGEM Test Center within the scope of compatibility checks. Our engineering service will assist you with your project-specific developments, adaptations and functional enhancements from project planning to the start of production.
