Measurement and I/O modules
The Cansas series by IMC (Germany) is comprised of a variety of CAN-based measurement and I/O modules. They are designed for the decentralized capture of physical sensor signals close to the point of measurement.
THE MODULAR DESIGN OF THE SERIES IS BENEFICIAL in centralized (e.g. test stand) environments, where users benefit from the signal conditioning modules, combined with digital I/Os, counter (incremental encoder) inputs, as well as analog and PWM outputs, to create modular front end interfaces for automation and test control systems. By utilizing a variety of different modules, users may create a front end for their CAN-based measurement and control systems. Tailored to meet the requirements of sensors, the modules are compatible with data collection systems equipped with CAN-interfaces.
Each member of the series includes these features: CAN-based synchronization for network-wide timing of every channel; CAN-based heartbeat to detect system or network failures; on-board real-time calculation to preprocess data, reducing the CAN network load; and TEDS (IEEE 1451) smart sensor recognition, simplifying connection and configuration.
The modules are available in five fan-less housing types, each optimized for a specific testing environment: beyond the two standard aluminum profile housings, there are compact, rack-mountable cassette types available, and a splash-proof, IP65-sealed line, the Cansas-SL. In addition, the μ-Cansas series offers 120 °C-underhood-rated single and quad channel units.
Data digitized by Cansas modules are transmitted in accordance with CAN standard (ISO 11898). This ensures noise-free, single cable installation of the modules along a CAN network, up to 1000 m from end to end. Every module includes user-configurable CAN settings, heartbeat to monitor system integrity, real-time preprocessing of raw signal data, and to reduce network load and simplify integration. The modules also offer an export of configuration information into the DBC format. The modules save their configuration in an onboard non-volatile memory. Once configured, the measurement will start according to its respective setting automatically upon power up.
Initial configuration (or subsequent reconfiguration) is done via the
CAN connection and one of three configuration methods:
First, the configuration software, which is connected via a compatible PC-to-CAN interface, such as the company’s CAN-USB interface. Second, a CANopen controller that has been configured with the basic module type information. Third, via the Studio data acquisition and control software, utilizing any of the company’s CAN equipped data acquisition systems. Utilizing Studio, a unified and scalable software solution for all of the company’s systems, permits the integration of the modules into an IMC-based measurement and control environment. It allows the user to design, control, manage, and automate the entire test and measurement workflow.
