CANalarm® - entry-level bus monitoring tool for plant operators
The latest member of the GEMAC CAN bus diagnostics tools, the CANalarm® is designed for the logical monitoring of CAN bus systems. This small device features two 9-pin D-Sub field bus connectors and plugs right into an existing and running CAN system. The CANalarm automatically detects the baud rate and starts to analyze the entire bus traffic independently.As a passive bus node, it detects without interaction and continuously typical characteristics of a CAN communication and compares it with user settable trigger criteria:
- Bus traffic load
- Number of error frames
- ID and content of the transmitted telegrams
Fields of applications:
- Redundancy in safety related areas
- Detection of faulty bus states
- Failure Monitoring: Detection of node failures and malfunctions
- Message Trigger: ID and / or content analysis for event-triggered alarm
The CANalarm® is an entry-level CAN bus monitoring tool for the start-up, analysis, monitoring, troubleshooting and service/maintenance of CAN bus systems:
- Passive CAN node, supports CAN 2.0A and B (ISO 11898-2)
- Power supply: +9 ... 32 VDC
- Displays ID and content of transmitted CAN frames
- Shows CAN bus load
- Detection of faulty bus states
- Taps directly into existing CAN cabling via dual DB-9 connectors - without the need for a PC or laptop
- Indication of occurrence of predefined trigger criteria via status LED or potential free switching output
- From the developers of CAN-Bus Tester - world-wide CAN diagnostics market leaders
