Display changes of CV values [4.4.0]

With software 4.4.0. or higher you can obtain a list of all changed CVs. The program internally records all CVs, which you have changed since opening the project. Once you save the project file, this list is deleted.

What is this good for? Let’s assume you want to prepare a programming list for a friend who does not have a LokProgrammer, but wants to change certain parameters of his LokSound decoder. With the aid of this list he can program all desired changes provided he has a DCC command station.

How is it done? We want to explain this function with an example.

First you must open (load) an ESU project file. You find numerous project files in the Download section. In our example we have opened the file 56533 (Piko Vt11.5). The current project file is displayed in the top row. Now we can execute the desired changes.

In this example the brightness of the lights should be reduced. And we also want to reduce the maximum speed.

Select the “Decoder” register, then “Motor settings”. Reduce the maximum speed from 255 to 200.

Select the "Decoder" register, and then function outputs. Select the output “Forward headlight [1]”. Reduce the brightness from 16 to 5.

Then select “Reverse light [1]” from the list. Reduce the brightness from 16 to 5.






Finally we want to display all CV values we have changed.

Select “Display changed CVs” from the “Extras” menu. Then a window opens that shows all CV values that have been modified since last saving the file (!). The values are grouped according to index values: In our example only one value has been changed in the index group (CV31 = 0, CV32 = 0), namely: CV 5 = 170. This is the maximum speed. Please note that the value of the index CVs 31 and 32 is irrelevant for all CVs less than 255 and may therefore be ignored.

You can see that the CVs 262 and 270 must be set to new values for the index group (CV31 = 16, CV32 = 0). That means that you should first write CV 31 = 16 and CV 32 = 0 and only then CVs 262 and 270.

We recommend to copy the content of this window into the clipboard by pressing the “Copy” button and to paste it into your email or word processing program. Thus you can archive these changes for later use.
