Background Dear friends, I am required to create a java program on a laptop to receive/send CANopen messages. RJ45 is chosen to be the network's physical medium. I am new to CANopen and Java communications programming. Pardon me if I appear to be uninitiated. The truth is, I have been reading up a lot but I still do not know how to get ...
This is continuation of the series of questions I have posted last week at http://stackoverflow.com/questions/423526/java-and-canopen. Thank you, Matli, for having answered all my questions. Current Situation I have to write a Java program to interpret CANopen messages. Due do certain circumstances, I am unable to get my hands on the ...
Hi, I am trying to understand the CANopen protocol. For now, I do not have any CAN hardware nor the CANopen stack to experiment with. I would like to know how to write a Java program to simply interpret CANopen messages that are received at the RS232 port. Questions Are there CAN interfaces that are installed as a serial port? Will I...
How do I listen in (preferably using Java) on a small set of well-defined CANopen messages without a commercial CANopen stack? ...
I thank Matli for having explained that the CAN interface API probably has functions to retrieve the ID, data length and the data of a CANopen message. Based on the explanation, one could tell if the frame is a PDO and derive the sender node's ID from the COB-ID. My next question would be, if the data contains more than 1 value, how do...
Can someone kindly explain what the EDS / OD are. how they are created and used? How it is that the OD comes in between the application and CAN interface? ...
I'm trying to find information on how to program an embedded mobile controller such as the ifm R 360. Where could I find specific information on the programming language used, the required development environment and any other useful information? From what I understand, the programming language is based on IEC 61131-3. What books or tut...
Assuming highest baud rate, what is the highest rate at which PDOs are received? ...
We have a robot project where the motor controllers use CANopen for communication. I need to communicate with these motor controllers using a Master microcontroller. The problem is that I need to develop a CANopen layer in this microcontroller but I only know how to send and receive at the low level (CAN). I don't know much about the CAN...
I know that the .NET Microframework supports the I²C bus. Are there some libraries for CAN or CANOpen too? If not, does it support CAN without using other peripherials? Can I build CAN support myself? Regards, Markus ...
I need an off-the-shelf CANOpen stack implementation as part of a Windows XP Embedded software solution I'm developing. Does anyone have any suggestions beyond IXXAT's offerings? ...
