CAN-bus option
The CAN-bus option is an add-on interface that allows integration of WIENER chassis and power supplies into a CAN field-bus network for remote monitoring and control.
- Integration into CAN field-bus systems
- Up to 126 crates controllable on one network
- Remote on/off and (for VME) SYSRES control
- Remote access to voltages, currents, trip points, temperature, fan speed, status, errors, configuration
- Intelligent protocol with broadcast, error reporting, task priorities, equal crate rights
Product Information
The CAN-bus option enables Kontron Hartmann-Wiener crates and power supplies to be part of a distributed control network. With this interface, a host computer can monitor and control a large number of crates through a resilient CAN network, accessing key system parameters like voltages, currents, temperatures, fan speeds, and error/status conditions. Because it supports up to 126 crates on one network and includes advanced messaging features (broadcast, priority, automatic error reporting), it is suitable for large installations with many power crates.
Technical data
| System | WIENER VME / VME64x / VXI crates (5000 / 6000 families), NIM and CAMAC with fan tray and PL508 power supplies |
|---|---|
| CAN BUS | Up to 126 crates per CAN network; 120 Ω termination resistors required at both ends of the bus |
| Control | Remote on/off; SYSRES (for VME) |
| Management & Control | Remotely accessible parameters (depending on power supply model): crate ID, voltages and currents, over/under-voltage trip points, current limits, temperature sensors (up to 8 per crate in VME 6000), fan speeds (average and individual), status signals, errors, configuration and adjustment |
| Interfaces & Protocols | Intelligent bus protocol (CMS-CAL compatible) supporting error messaging, broadcast and group functions, priority levels and equal rights among crates |
