Answering my own question. Not sure why the GUI wasn't allowing me to change the gateway address, but I found the answer here In summary, I pretty much just edited the "interfaces" file in the PowerPmacIP folder on the flash disk with the correct IP, subnet mask, and gateway address. As the link above stresses, make sure to make a backup just in case. Putting the card back into the PMAC ( I guess alternatively you could edit the file by ssh-ing into the PMAC) and upon power up, the PMAC will take on the new settings. thanks for your help!

Hi, I've followed the instructions in the manual to changing the IP address of my PMAC via the GUI, however, when I change my default gateway to what it should be, it keeps going back to what it used to be and makes the PMAC inaccessible. 1) How do I properly change my default gateway IP address so that it sticks? 2) Is there any way that I can change the IP address via line command? thanks windell

Hi All, I saw a previous thread, but I want to repost to see if anyone has any more input. I'm uploading a set of code to the PMAC and it says "Mapping Power PMAC variables Failed" when I do a build. I looked at other threads and saw the suggestion to make sure the pp_disable.txt exists in the Log folder. However, I don't have one in my Log folder and it used to build fine. So I'm not sure what I could be doing wrong. Any suggestions? thanks, windell

The version I'm using is 1.6.0.109. The firmware on the PMAC is 1.5.8.0. The variables I'm changing are Motor[x].MaxPos Motor[x].MinPos Motor[x].JogSpeed Motor[x].MaxSpeed Motor[x].Servo.Kp Motor[x].Servo.Kvfb Motor[x].Servo.Ki thank you very much for your time!

Thanks Steve. Its odd, I've tried doing that, but when I do a reboot the configuration goes back to what it was before. Here is what I'm doing. I launch the IDE, and open the configuration file via DeltaTau-->Configure-->Setup Variables. It prompts me if I want to load the file to the PMAC. I choose load and it uploads. Then check the variables manually via the terminal window to check to see if they've changed. They do. Then I do a save and a reboot. When the system comes back up I check the variables again and they have changed back. Is there something that you see that I'm doing wrong?

Hi, I'm trying to find the list of parameters in the configuration that are write protected. Searched the PMAC manual and I don't see a list anywhere. Anyone know? thanks, windell

Hi, I'm attempting to upload a new configuration file via Setup Variables. However after uploading it I've done a reboot and I've realized that the configuration changed back. How do I permanently apply my changes? I've issued a Sys.WpKey=$AAAAAAAA command before doing so, but it didn't help. thanks, windell

Aloha, I have a setup that uses absolute encoders for crude positioning and then incremental encoders for tracking. Maybe this is obvious, but I'm new to PMACs, how would be a command that I would issue to reset the incremental count when I'm switching between encoders? My motors are 0 and 2 and the encoder table entries are EncTable[1].a for incremental for motor 0. EncTable[3].a for incremental for motor 2. thanks windell

Wonderful! Thanks! After I set this, where would the source code be located on the PMAC?

Forgive me, but when I compile my code I see in the build feedback "Downloading x.c to power pmac". This leads me to believe that the source is uploaded to the pmac and then is compile onboard. I apologize if this is a dumb question or and RTFM answer.

Hi, I'm pretty sure I already know the answer, but are there any PMAC training available online? I see the training slides on the forum, but wondering if there are any videos that come along with them. thank you, Windell

Hi, Is it possible to download the last version of the code that was compiled and uploaded to the PMAC? I'm not talking about the compiled binaries, but the actual source code. thanks, windell

thank you very much for making my eyes look elsewhere! It all makes sense now.

I'm new to the PMAC and in my application I know that sending the #2v online command will give me the velocity of motor 2 via a tach voltage read by ADC channel 1. I'm trying to change so that sending #2v reads the voltage on a different channel. How might I do this? Where do I configure this? thank you, Windell
