Description

CANwatch is an analyzer supporting easy error detection during installation and operation of CAN networks. CANwatch judges the analog signal on the bus and detects errors like e.g. invalid levels, overshoots, slow slopes and short circuits within the signal lines. Besides the diagnosis of problems during installation CANwatch offers the possibility to detect signal deficiencies below the level causing failures. This allows preventive error detection and thus an increase regarding the availability of automated systems. Errors on the physical level of the CAN bus cannot be detected by protocol analyzers and could until now only be analyzed by specialists with expensive and bulky hardware. Due to the easy diagnosis and display with LED’s CANwatch offers fast detection and correction of errors also to installers and plant operators.
