Select Baud Rate on PV750

Dai Uematsu · Post by **Dai Uematsu** » Wed Nov 09, 2011 3:43 am

Our customer asked us to confirm if they can select the baud rate of the PV750. The baud rate can be changed with the PowerVision Studio, but it cannot be selected on PV750 though PV101 has this function. Will you add this function to PV750?

Best regards,

Hello Dai Uematsu

You can in fact change the baud rate on the PV750. There is a variable called "Serial Port 1.BaudRate" that you can change. Then use the "MODBus Port Manager.UpdatePort" action in a state machine to update the port with the new baud rate.

I think your proposed method is to change the baud rate by using the PowerVision Studio. What our customer is requesting to confirm if the baud rate can be selected from the PV750 display menu(NOT through config. tool).

Thank you,

Here is a simple configuration that shows how to change the baud rate via the PV750.

The "Current Baud Rate" is mapped to the "Serial Port 1.BaudRate" variable. The buttons on the right execute a state machine called SM_ChangeBaudRate that changes the variable and updates the port.

I am sorry that I do not understand how to use the file "change baud rate" you sent. Please let me know how I should use the file. By using the file, can I select the baud rate from the PV750 utility menu?

Thank you,

The ChangeBaudRate file that was attached is a murphyConfig file in a zipped folder. After you unzip the file, you can open it with PowerVision Studio and load it onto a unit from there. It is just a simple configuration that gives an example on how to set up a configuration to be able to change the baud rate from the PV750. You would need to take the same ideas and implement them in your configuration so users can change the baud rate from the utility menu.

We were able to load the configuration into our PV750 and the baud rate was selected by pressing buttons on the right side. We now know that PV750 does not have the baud rate selection feature on it.

Thank you,

Regarding the baud rate selection on PV750, our customer asked me to confirm if you have a configuration sample which can select the baud rate of the CAN port(The previous sample was for Serial ports). If you have one, please share it with me so that I may send it to our customer.

Regarding the PowerVision Studio, with Ver.2.2, the DB folder had .db3 format, but with Ver.2.3, the file format is .murphyConfig. Did you change the .db3 format file to .murphyConfig format file(You will not use .db3 format any more)?

Best regards,

The baud rate for the CAN ports can only be changed in PowerVision Studio, not on the PV750.

Starting in 2.3, the DB file format has changed to murphyConfig. The .db3 format will not be used. You can still import configuration from 2.2 to 2.3. The file format will automatically be changed to murphyConfig.

1) Regarding the baud rate selecting on PV750, our customer asked us to confirm if FWM has any plan to add this feature(selecting CAN baud rate on the PV750/450) at the next update of the software. Please give us your comment.

2) The configuration made with PowerVision Studio Ver. 2.2 is not compatible with Ver. 2.3(We know the old configuration made with Ver.2.2 can be imported to Ver.2.3). When the version goes up(Ver. 2.4, 2.5, ...), a configuration made with older version is not compatible with the latest version.

3) With the PowerVision Studio Ver.2.2, when the create button on the top tool bar is pressed, then a .db3 file is created in the DBs folder and an "update.tar.gz" file is created in the created configuration folder at the same time.

With the PowerVision Studio Ver.2.3, only murphyConfig file is created in DBs folder. You mean that you do not need the "update.tar.gz" file any more. Is that correct?

Best regards,

Hi Dai Uematsu

1) We will add the option of changing the CAN baud rate on our backlog for a future release.

2) Are you trying to put a 2.3 configuration on a unit that has 2.2 firmware in it? If so, you will have to do a full install from the latest config tool to get the latest firmware on the unit.

3) 2.2 did save the update.tar.gz file to the computer's hard drive. 2.3 does not save the update.tar.gz file to the hard drive unless you select "Save to Disk" after you press the Create button. 2.3 still uses this file to load to the unit, but it stores it in memory instead of the hard drive (unless you tell it to).

1) Thank you for adding the requested feature of selecting CAN port baud rate on PV750. Do you have any plan to update the software?

2) Your understanding is correct. Is it possible to reserve the compatibility between the latest configuration and the previous one so that our customers can directly load the file to the unit they have. It is not user-friendly if our customer must do a full install every time FWM update the version because we cannot know when new version was released at FWM(Often times, our customers(or even we) are not aware of the new version has released.

3) Thank you for your explanation. I provided this information to our customer.

Best regards,

Yes, version 2.4 will be released in the near future. I am not sure when the CAN baud rate issue will be implemented, but I know it will not be in 2.4. It would be in a later release down the road.

At this time, the version of the configuration and the version of the firmware have to match. To make it easier, just do a full install each time the version of PowerVision changes. For example, when you downloaded PowerVision 2.3, you would have done a full install so the versions matched. Then, when 2.4 is released, you would do another full install.

Thank you for your confirmation on the full install when new version is released. Our customer would like FWM to keep the compatibility between the latest firmware(for example 2.3) and the previous configuration file(for example 2.2) because it takes time to complete a configuration and new firmware could be released while customers are working on a configuration with the current version.

Regarding the change from automatic save of the update.tar.gz in to the hard disk to save in memory, is there any specific reason to do this way? Our customer thought that it was very convenient to save the update.tar.gz file into the hard disk automatically(Now they need to specify where the file should be saved every time).

One new question from the customer is that the J1939 source addresses like A,B, and D are updated only after power cycle(The PV750 should be turned off to update the CAN source addresses. This is not convenient for our customer to use the PV750 for their internal test equipment. Do you have any method to reflect the cAN source address change without power cycle?

Best regards,

Dai Uematsu

I see what you are saying now about the firmware being backward compatible with earlier configuration versions. I'll make a note of this request.

The reason why PowerVision does not automatically save the file to the hard drive is so it doesn't take up unnecessary hard disc space unless the user requests to.

Currently there is not a way to change the source address of a CAN port without a power cycle. I will make a note of this request.

Thank you for your support. I provided all the info. to my customer and look forward to improve the items in the future.
