VBA: find and replace a XML node

Asked 2020-Dec-17 at 14:13

I have an XML file defining the processes and some other parameters, which will be loaded by a CAN controller at start up. I will use this as a template for differrent controllers, so I need to manipulate the items in some sections of the XML. In particular I will be defining different Subcomponents and modifying some of the existing ones. And I have to use Excel VBA to handle all this stuff: eventually there will be tenths if not hundreds of controller with different definitions.

I've managed to get around the process of cloning and appending new nodes, but it looks like my brain is refusing to grasp the concepts behind the XML parsing, editing etc.

My problem at hand now is how to find and replace (or not if one or more attributes already satisfy some conditions: path on disk mostly) a child node of the Subcomponents tree. Here the template:

It is very easy to achieve by using XSLT. You just need to call XSLT from VBA.

XSLT will process your input XML and generate a new XML file:

You can use Element.getAttribute() to get attribute alt as event date for check in script.
Then check if the current date passed event date, redirect by change site's location, or do anything else you like otherwise, if the element has redirect as default behavior (like a tag), you will need return false; to prevent default behavior.

QUESTION

Sending events (async data) in CANopen with more than 8 bytes of data

Asked 2020-Sep-08 at 07:58

We are developing a typical CANbus networked system with what you could call a controller organizing a number of devices.

The devices needs configuration, which the controller writes (and might also read back) using regular object dictionary items (currently in the manufacturer specific range).

The devices also perform actions (commands) with more than 8 bytes of data and this we solve by having write only items in the device object dictionary and relying on the regular segmentation/de-segmentation of SDO's. (I don't know if this is the CANopen way of doing things, but it seems reasonable).

However, the device also produces events (say some sensor data passes a certain threshold) resulting in more than 8 bytes of asynchronous data coming up from the device. PDO's are meant to be used for sending async event data, but it can only contain 8 bytes. The devices could write the data into an object dictionary item on the controller, but this doesn't seem like the CANopen way. Am I right?

The best we've come up with is to send a PDO to the controller, informing the controller that more data are available in the object dictionary on the device.

Anyone with CANopen background that can way in on the best (CANopen) way of solving this?

Since I'm repeating 8 bytes a lot, we can safely assume that this network is not running CAN-FD.

Answered 2020-Sep-08 at 07:58

The key of any sensible CAN network design is to consider real-time, data priorities, bus load and data amounts early on. If you find yourself with a chunk of data larger than 8 bytes, then that strongly suggests that something is wrong in this design - it should likely be split in several packages.

Generally, you shouldn't be using SDO for data at all, since they come with overhead. That includes writes to the object dictionary, which also means SDO access. Block transfers etc with SDO are meant for things like bootloaders or one-time configuration, not for live data traffic in operational mode. It can be done, but it is fishy.

You can in theory map data across several PDOs with PDO mapping, but all of this really sounds like an "XY problem" - you are convinced that you need to transmit larger chunks of data and look for a way to do it. But step 1 is to look at the fundamental network data/design and see if you actually need those large chunks or if it makes sense to split them in several. The ideal CANopen design is to have one PDO per type of data, when possible.

How to Calculate CRC Starting at Last Byte

Asked 2020-Aug-01 at 00:14

I'm trying to implement a CRC-CCITT calculator in VHDL. I was able to initially do that; however, I recently found out that data is delivered starting at the least-significant byte. In my code, data is transmitted 7 bytes at a time through a frame. So let's say we have the following data: 123456789 in ASCII or 313233343536373839 in hex. The data would be transmitted as such (with the following CRC):

I'm pretty new with CANopen, and also a little bit shooting in the dark...

Looks like cantools might do the trick:

https://pypi.org/project/cantools/

It can decode CAN data using a DBC file. For actually reading the CAN bus it integrates with python-can.

https://python-can.readthedocs.io/en/master/index.html#

To read CAN data from a log file there's a module in python-can for that

https://python-can.readthedocs.io/en/master/listeners.html

And finally if you want to interact directly with a live CANopen bus there's the CANopen for Python library

QUESTION

CANOpen protocol overhead

Asked 2020-Mar-06 at 12:31

Can someone help me understand how much overhead CANOpen protocol adds on a CAN bus. In other words, if a node is generating a CANOpen PDO message of 8 bytes of application data, how much header/overhead does CANOpen protocol itself add? I'm not talking about the overhead of CAN bus itself which are the CRC, DLC, RTR, EOF and other bits. What is the extra load on the bus for using CANOpen vs using CAN directly. Thanks.

...

ANSWER

Answered 2020-Mar-06 at 12:31

There is no "CANopen protocol" as such, it's the name for the whole application layer. Simplified, the actual protocols used by CANopen boil down to:

NMT frames, network management. Controlling the state of nodes and the network as whole.
SDO frames, service data objects. Configuration of individual nodes.
PDO frames, process data objects. The actual data frames.

There's various other special-purpose ones such as EMGY, LSS etc as well, but the above are the main ones.

In other words, if a node is generating a CANOpen PDO message of 8 bytes of application data, how much header/overhead does CANOpen protocol itself add?

PDO have zero overhead. You get 8 bytes payload in an 8 byte PDO frame.

SDO and the various NMT have some overhead though, typically 1 byte.
