I installed IDE on another workstation. And it works without any issues. I think there is some issue with my laptop setup. Thank you all for your responses.

@Eric. When I open "Plot" it opens up in Legacy mode. I have also installed version 3.1.4.0 of IDE. I have both versions installed now. I have disabled the firewall from Trend security agent. For both versions with the firewall disabled, I still see the "upload data" taking a long time and not succeeding.

@Tony I do not see it listed under "Allowed apps" All, I am using IDE version 4.0.3.0

Thank you for the responses. I need to schedule this work again and will get back here when I have some feedback from my end.

I found instructions on how to do gathering and plotting using IDE. The issue that I am hitting right now is that I am unable to upload the data. It is taking a long time and I think uploading does not work. Any suggestions on where to look at?

I am troubleshooting an issue related to a servo motor which we use to drive a monochromator Bragg axis. At a specific range of the motion, we observe that the x-ray beam jitters possibly due to motor oscillation. The motor is driven by an external amplifier and we use power PMAC for torque control. The motion is typically carried out by executing a motion program. We first observe the issue with our data. Afterwards we jogged the motor in the questionable range and was able to narrow down on the range where we see the oscillation. The x-ray beam stabilize upon killing power to the motor. I am guessing that the motor is trying to correct its position during this range. In any case I want to plot relevant variables by gathering data. I have not used the plotting feature for gathering and also not gathered data before. Need some help for the following #1. Determine which variables to plot #2. What is the procedure for plotting given that I can run a trajectory from EPICS controls to execute the motion program Thank you.

Just an update here. Our system is a UMAC rack with accessory cards installed.

All, After a power dip, we can't any longer communicate to our power pmac. On the RG45 interface, both lights come amber and one of them blinks. I tried pinging the device locally using both set and default IP addresses. I have no success. Can I connect via serial to debug the issue? Can I reset the CPU card to fix the issue? In general, I want to figure out whether the power dip damaged the CPU card or not. Any guidance on how to proceed with testing is much appreciated.

Okay. Thank you, Steve. Chanaka

Hi All, The Turbo PMAC that I am working on does not have a MAC address assigned. How can I resolve this issue? Thanks, Chanaka De Silva NSLSII controls

Thanks Richard. Open loop is now good. I was cloning from a working example and did not check in the manuals for DAC specific information. - Chanaka

Hi All, I did few checks and found few issues. 1. Incremental encoder count sign is swapped between the external driver and Power PMAC position read back. I fixed this by swapping the phases. I found the relevant software fix for this. However, for now, I fixed the issue by swapping the cabling. 2. I then tried OPEN LOOP commands. - #1out1 : This gave me a full -10V output - #1out-4 : This gives me the full +10V output Now I need to swap the polarity and fix the scaling such that #1out100 should give me a +10V and vice-versa. I believe this polarity issue is affecting my JOG. Can someone point me to the functions to accomplish those (polarity + scale) changes? Thanks, Chanaka

Dear All, I am using the product PBC4-G21-000-A000000 to drive a SERVO motor via an external driver. The driver requires Single Ended DAC output wiring. I am facing the problem that my motor only moves in one direction. I checked the DAC output and figured that it only outputs positive voltages. I am probably missing something in the motor setup. Can I get some input on how to debug/fix this issue? Thank you, Chanaka

Thanks for the reply.

Hi All, I am trying to locate ACC-24E3 manual. I looked up under accessories but could not find it under "Manuals" section. Can someone point me to it. Thanks, Chanaka
