Function and features

CANview RS232 is an active CAN interface for the connection of a CAN fieldbus
system to a serial RS232 interface (e.g. PC interface).
The main applications for CANview RS232 are to enable the user to do program
downloads, online diagnostics and system performance monitoring from the user
PC interface via the CAN network.

Overview of data

Depending on the configuration the interface can transmit and receive standard
messages (11-bit identifier) as well as extended messages (29-bit identifier). The
CAN baud rate can be freely selected according to the CiA standard.
CANview can be used safely due to its large supply voltage range of 9...36 V DC
and the electrically separated RS232C interface.
The baud rate (up to 115.2 Kbits/s), handshake, parity, etc. can be set on the
RS232 side.
CANview can only be used with the following software packages:
plus
• ecolog 100 Version 2.1 (programming software) or higher
• CoDeSys Version 2.3 (programming software) or higher
• Downloader (download tool for R360 control system)
• CANmon (ifm CAN monitor)
• CANcom software and tools (communication software for the CAN/GSM
modem)
In the event of special requirements more unit parameters can be set via a sepa-
rately available configuration software (for diagnostics and test purposes or for
EMV-critical applications such as modifications to the CAN transceiver waveform,
e.g. vary the rising edge rate).
The automatic recognition of the CAN bus baud rate is supported from the hard-
ware side.
A CAN bus terminating resistor which can be switched on or off is integrated in
CANview.
The supply voltage as well as the static level of the CAN signals can be measured
using the A/D converter of the microcontroller.
