• node failures
• faults in the communication
• complete standstill of the plant

often have their origins in the physical bus characteristics. The CAN-Bus Tester 2 provides an overview of the signal conditions on the bus, which helps you to locate and rectify frequently occurring error causes instantly. During the installation phase of CAN bus plants the integrated wiring test is especially useful. It is possible to check the bus cabeling by using different measurement methods and thus the transfer properties are ensured. You can also perform comparing measurements directly on the running plant over its lifetime and thus prevent standstills.

For long-term monitoring of CAN bus systems GEMAC developed the CANobserver®. The CAN-Bus Tester 2, the CANobserver®, the CANtouch® and CANalarm®– form the CAN-Bus diagnosis family.

Protocol Monitor CANopen (Receive):

• Support for analyzing CANopen based systems
• Interpretation of all received telegrams according to CANopen specification
• Messages are decoded and displayed as SDO, PDO, NMT, Sync, Timestamp, Heartbeat and Emergency objects
• The content of the PDOs can be shown symbolically by loading the dedicated EDS/DCF-files

The information will be displayed in a continuous mode (Scroll-mode) or in form of a list sorted by CAN-identifier (Overwrite-mode). Once the overwriting mode is active, changes are highlighted. A powerful filter for Node-IDs and object types simplify the analysis. Abort codes are shown in plain text. For using the Protocol Monitor CANopen our new software version v4.1 and the appropriate license key are required.

Protocol Monitor CAN (Receive/Transmit)

Receive:

• Display of CAN error frames and overruns
• Trigger on these conditions
• Start, Stop and Pause records are displayed

Transmit:

• Summarize CAN telegrams in a list (sequences)
• advantages:
  • transmit several CAN messages once or repeatedly with defined intervals
  • configure connected devices with just one touch of a button
