Diagnostic options for CAN communication
Bus Diagnostics
Software tools
The following software tools are integrated in MOVITOOLS
®
MotionStudio for testing
and diagnosing communication via CAN. The diagnostic PC is connected to a CAN
network via PC-CAN interface for this purpose (see chapter "MOVITOOLS
®
via SBus").
• PCANview
PCANview shows all the telegrams transmitted via CAN and provides an overview of
cycle times and number of telegrams. PCANview also allows for sending individual
telegrams.
• sCAN
sCAN is a data and telegram monitor with memory function for CAN networks. The
display can be set according to the profile and matching the data transmitted via
CAN. Filter settings, the definition of a trace file to which the read-in data is written,
and other analysis options offer all the functions required for diagnosing the CAN.
To start the programs, shortcuts are created under [Start] / [Programs] / [SEW] / [sCAN
and PCAN Tools] when installing MOVITOOLS
®
MotionStudio.
Example: Process
data exchange
using PCAN View
For exchanging process data between PC and MOVIDRIVE
®
B via SBus (CAN),
connect the USB-CAN interface as described in chapter "Communication SBus (CAN)
via interface adapter". In MOVIDRIVE
®
, you first have to choose the MOVILINK
®
profile
using P880/890, read the SBus address P881/891, and read the SBus baud rate using
P884/894 (e.g. with the DBG60B keypad).
Now start the PCAN View program. At the beginning, you have to choose a network with
the baud rate matching MOVIDRIVE
®
. If no suitable CAN network is available for selec-
tion, you can create CAN networks using the PCAN Nets Configuration program. The
created networks will be available next time you start PCAN View. The selected baud
rate [4] (here: 500 kBit/s) and the USB symbol [3] are displayed in the status bar of
PCAN View.
A new transmit message is created for sending process data:
• The identifier [6] is calculated as described in the "Telegrams" chapter as follows:

SBus a 3 (here: 8
