PC / Neuron M103 connection problem
-
I am having problems with my Neuron M103 PLC.
Since September, I have been using a Neuron M103 to manage a control box for plasma wave manipulation. So I initially followed the instructions and tutorials available on your site: unipi.technology in order to program the Neuron and carry out this project. For this I had a 16GB SD card from Kingston on which I had downloaded the OS image (in ZIP folder with BelenaEtcher software). In addition, I downloaded the Mervis IDE software and was able to complete my project properly. However recently I needed to modify something in the control box of this manipulation and had to remove the Neuron from it. This had the effect of "destroying" the SD card since it no longer worked after removing the Neuron.
So, I researched your site's forum if there was a reason for this and, indeed, you recommended using a SLC SD card of at least 2GB. I then ordered 3, 2 from the Apacer brand (in 2GB) and 1 from the Swissbit brand (in 2GB also). After reception I did the same as I did initially, with the tutorials, but I can only upload my program to the Neuron once before it crashes. Indeed, when I launch the deployment of the program these error messages appear:- Error PLC 0 1 error during upload:
SSCP Exception(NoResponse) ''
Or:
- Error PLC 0 1 error during upload:
SSCP Exception(Disconnected) ''
Or:
- Error PLC 0 1 Setup of executable image incomplete due to errors.
- Error PLC 0 1 Failed to check target controller - SSCP Exception(FailedToConnect) ''
- Error PLC 0 1 Failed to upload file '' (FailedToConnect)
So, I looked on your forum for answers to deal with this problem but no one is talking about this type of problem there, what can this be due to?
I tried the other 2 SLC SD cards that I ordered, but same results, the download is only done once, the first time the program is launched.
I also tried with the new version of Mervis and using the latest version of the image OS available, but nothing helps, it still crashes ...
Have you ever encountered this type of problem? And how to solve it? - Error PLC 0 1 error during upload:

Hello @Mathurin,
try reattaching the PLC into the project - Right click on PLC -> Attach Controller.Best regards,

Thank you for your quick reply.
I have just made the connection of the PLC but it still does not work, same error messages ...
I forgot this information, before displaying the error messages, the information bar at the bottom left of Mervis displays: "Uploading image: 98% transferred ..." for at least a minute when I try to deploy the program. Maybe this will help identify the problem better?

Hello @Mathurin ,
this looks like the network connection has been broken during the upload. What is your network situation - what sits between your PC and the PLC? -
Yes it also seems to me but there is no reason for it, my PC is connected to a docking station and the Neuron connects this station with an ethernet cable. In addition, since September I have not changed this installation and everything was working normally. And, what is most astonishing is that when I reset everything and I start again from 0 with the start-up procedure, I manage to deploy my program correctly for the first time, then everything crashes and I do not can no longer perform anything.
I may have found something interesting, my 2GB microSD cards do not have the microSD HC inscription on them, so I think they are simple microSDs, could this block the reading of these cards by the Neuron?
(On your site, the image corresponding to the 2GB APACER microSD SLC cards does indeed have the inscription HC and yet when you order them, the cards do not have the same inscription, it's strange) -
Hello @Mathurin,
I'm using the said SD card (without the HC) extensively and haven't encouter such behaviour, yet. Please, archive the whole Mervis project folder and send it to [email protected]. I'll try to replicate the issue here.
Also include the version of IDE you are using and the version of MervisOS image.Thank you and have a nice day,
Martin
