CAN Configuration

CAN

CAN-Addressing

The CAN-interface is configurable in three different ways. These are the Special-mode, the Softwaremode and the DIP switch mode.

Special mode

The usage of this mode is, to set the CAN-interface quickly and easily to default values. This is helpful for a quick and easy setup and facilitates an error analysis or an initial operation.

Software mode

The software mode is to fully setup the module, using an included software. It is possible to set up:

Transfer rate
CAN 2.0A (11 bit-addressing, "base frame format") oder CAN 2.0B (29 bit-addressing, "extended frame format ")
CAN-interface address
Response-Modul-Address (responses are sent to this address)

Software to configure the CAN-interface

With this software, it is not only possible to store or load the stored configuration values, but also to see the actual set up values of the module. An error analysis is thus greatly facilitated.

DIP-switch mode

The DIP-switch mode is to manually configure the CAN-interface by using DIP-switches. The DIP-switch configuration may be read out, using the DELIB-Configuration Utility. A configuration-check is therefore easy and simple.

Controlling of the CAN modules

Accessing to the RO-CAN modules over the CAN- interface happens by the following ways.

Automatic Sending Mode

The modules are able to send CAN packets automatically in a definded time interval. The time interval can reach from millisecond to second. The following picture shows a packet, which will be sent to the CAN-address 1234.

Automatic Receiving Mode

An automatic receiving on four different CAN-addresses can be configured individually. Also you can define, if the received CAN datas should be given out to relays or D/A converters. The following picture shows a packet, whose datas are sent to the CAN address 543.

A timeout protection switches the relays or D/A outputs, in failure, automatically of.

Also the user can activate a timeout protection. If the RO-CAN module cannot receive any CAN packets after a defined time interval, the module disables all outputs and set the D/A outputs to 0V.

DEDITEC CAN Addressingmode

A special CAN protocol, which have been developed by us, allows registry control to all functions of our modules. So are BYTE-, WORD- and LONG- accesses possible. A registry- and protocol description can be found in our download area.

Configuration by a graphic Windows configuration software

All CAN-addresses, CAN-speed and packet options can be set up from the user, over a special Configuration Utility for the RO-CAN serie. The configuration works over a free serial interface of a PC. Predefined CAN-addresses and several modes are adjustable by DIP switches.

Software-updates and start-up of the RO-CAN modules

Further to the delivered Windows driver library, the RO-CAN modules can be tested and updated with newer firmware. Over graphical testprograms, the modules can be tested and configured (without using the CAN-interface). So you can do test measurements and check the electrical wirings. Are all settings configured, the module can be connected to the CAN-interface.
