Installation tester for CAN networks
CANcheck allows users to analyze CAN networks during commisioning, maintenance and helps searching faults. This battery-operated, hand-held device connects to the CAN network to be tested and operates using a clearly-structured menu.
Functions
Cable test with network switched off and operational test with network switched on
Wiring test: test of the resistances between all pins of the CAN-connector (assignment in accordance with CiA), providing assessment based on pre-defined threshold values
Terminal resistance test: measurement of the resistance between CAN_H and CAN_L
Cable length: measurement of cable length via pulse-time delay, cable impedance
Measurement of the signal level: absolute and differential signal level listed according to identifier
Baud rate detection: detection of baud rate of the tested CAN system
Identifier scan: determination of all identifiers transmitted and display of reception frequency
CANopen mode: Signal level and reception frequency listed according to node-ID
Bus load: measurement of the current bus load of the CAN system
Error frames: number of error frames per time unit
User’s guide: test instructions before the test, OK or error message after the test, continuation after acknowledgement
Multilingual: test instructions in German or English
The CANcheck is operated by means of a simple menu control via cursor keys and LCD display. Test results can be output via the LCD display or a connected PC.
For display of the results on a PC, the CANcheck is connected to the PC via a USB port. Results are displayed on the PC via a terminal program. The logging function of the terminal program enables the test results to be either archived in a file or printed out.
