<br>
Based on Alberto's response this morning I think your explanation was very helpful. They are performing live insertion/extraction tests and load tests today using the board you loaned them. I know he asked you guys to perform similar tests.<br>
<br>
You guys are extremely thorough and do very comprehensive tests, which is fantastic. Please don't feel obliged to put together a report for our benefit if you've already done this or if you can do these tests in the short term. If you have to develop a report
for internal protocol I understand, but if you can put together a quick response it will save time and put the ball back in his court (which at this point is good IMO).<br>
<br>
Cheers,<br>
Greg<br>

Greetings Alberto,</p>

Thank you for getting back to us so quickly. As you saw in the meeting minutes, GECO 2020 seems to be working well when the EPICS service is disabled and there is no load connected to any of the modules.</p>
<p style="margin-top: 0px; margin-bottom: 0px;margin-top: 0px; margin-bottom: 0px;margin-top: 0px; margin-bottom: 0px;margin:0in 0in 8pt; line-height:107%; font-size:11pt; font-family:"Calibri",sans-serif">
A couple of points of clarification: </p>
<ul style="margin-bottom:0in">
<li>The first issue, the random parameter changes, has only been noticed when the EPICS service is enabled and no load connected. As of this moment, we have not yet tested any of the modules with the EPICS service enabled
<i>and</i> the load connected. </li><li>The second issue, the board disconnection, has been observed when there is a load is connected to a module. Additionally, the board that loses connection is not necessarily the board that has the load connected. A couple of times it was just a random board
populated in the crate.</li></ul>

So, to the first issue, we would like to use the same EPICS service that you use in order to rule out any issues with our EPICS service.</p>
<p style="margin-top: 0px; margin-bottom: 0px;margin-top: 0px; margin-bottom: 0px;margin-top: 0px; margin-bottom: 0px;margin:0in 0in 8pt; line-height:107%; font-size:11pt; font-family:"Calibri",sans-serif">
And to the second issue, the load we are using is 2 M<span style="">§Ù (mega-ohms) on each of the 36 channels. For the board disconnection issue, we were using only GECO 2020 to control and monitor the boards. We are currently running additional tests with the
load connected and using only GECO 2020 to control and monitor. I will let you know if we observe similar issues.</span></p>
<p style="margin-top: 0px; margin-bottom: 0px;margin-top: 0px; margin-bottom: 0px;margin-top: 0px; margin-bottom: 0px;margin:0in 0in 8pt; line-height:107%; font-size:11pt; font-family:"Calibri",sans-serif">
<span style="">Also, are you able to tell us if we have all of the most current firmware versions (for the crate CPU, modules, and HiVoCS)?</span></p>
<p style="margin-top: 0px; margin-bottom: 0px;margin-top: 0px; margin-bottom: 0px;margin-top: 0px; margin-bottom: 0px;margin:0in 0in 8pt; line-height:107%; font-size:11pt; font-family:"Calibri",sans-serif">

<div><tt>Hello Aaron,<br>
<br>
<br>
I read your report and I'm happy that the new firmware fix the latency issue, we verified it in our setup but we were waiting for your feedback that was the most important.<br>
<br>
Obviously I'm sorry that you have other issues, unfortunately we were not able to reproduce in our tests this is the main reason why we already don't fix them<br>
<br>
I identified two main issues, the first is the random parameter change, the second is the board disconnection.<br>
<br>
If I well understood both issues happens only when a load is connected to a module and probably this is the reason why in our tests we didn't reproduce the issues.<br>
<br>
I think we have to use the same load on our (to tell the truth is yours) A7030TN to see the issue, so can you give us details about the load?<br>
I noticed that from your first test (i.e. GECO and board without load) that doesn't have problems and the one that have issues (random parameters) two, let's say, "variables" are changed, one was adding the load and the second the use of the EPICS service.
I would ask you if you could repeat the tests (to see if random setting happens) connecting the load but disabling the EPCIS service. This is very useful for us to understand if the issue is on the firmware boards (because of the load) or in the EPICS service.
We'll do the same test here but we need to know details about the load so if you for you is not a problem to do this test it will speed-up our job.<br>
<br>
I wouldn't face the second issue because maybe it is related to the first and in any case I prefer to put our effort to fix one issue at a time.<br>
<br>
<br>
Best Regards,<br>
Alberto<br>

<br>
Aaron, thank you again for providing us with the very clear and concise report. In speaking with CAEN, I think the for efficient way to resolve these issues is to simply put the CAEN engineers and the DSG group on the same page by way of this email.<br>
<br>
CAEN has received your notes regarding the status of EPICS client control of the SY4527 mainframes and will provide a very complete response to you via this email string. We realize how critical this issue is and very much look forward to working together
with you to resolve it!<br>
<br>
Kind regards,<br>
Greg<br>
