Hello, I have many stations sending data to a FTP some years now, recently update the OS to some stations and note thet the Headers in the FTP files appear in each send data, i assume that is a change or problem in the last OS (CR300, CR6 and CR1000X),,, please can you hel me on this?
The program have configured the FTP instruction like this:
Function well many years but now add the headers every time that the data is send to the FTP Server
Thank you in advance for your help
What OS version are you running on your different dataloggers? The most recent OS for the CR6 and CR1000X haven't had any changes to the FTP function. Do you know if your FTP server has had any updates to it's FTP service or permissions changes to the directory that files are being FTP'd to?
The CR1000X have OS 04.02, before the problems have the OS 03.01, as the users talk to me, before the update of the OS there was not problems in the FTP data, after the upgrade in the OS they note that the headers start to appear in the data so for this reason i think something change in the last OS,
Other clients also talk with me and mention that their data also is comming with headers, the OS they have installed are:
CR6 OS 10.02
CR1000 OS 32.05
CR300 OS 10.03
CR1000X OS 04.02
Could be just coincidence but the users mention that before the upgrades there was not problems in the headers, this problem happend with different clients also in different servers..
Thank you for any comment
hi! we are glad to see you here! I'm new too and just wanted to say hi to everyone
I'm going to email you and ask for more information.
We have had the same problem in our measuring network, based on CR1000 and CR6 loggers (with last OS). The problem started without any change in our data-loggers configuration/programs. We supposed that the problem was a change in FTP server configuration (there was a change in the welcome message of FTP server exactly at the same time). Unfortunately, we have not received any information about FTP server configuration change, since it is hosted in a commercial platform.
You might consider changing your FTP platform. I've had this happen with a handful of customer all in a short time and they have all been using an online cloud hosted platform for their FTP. It's possible that changing your FTP platform will address the issue since we're assuming that the FTP service has undergone a change via updates.
Posting an update on what was discovered in a similar case, to close out the issue.
In that case, the customer had switched to using an FTP server which would not allow the datalogger to read the list of files on the server. The FTP account the datalogger is using needs permissions to allow seeing the list of the files. When the datalogger is not able to see the list of files, it must assume an existing file does not exist on the server. Then, the datalogger will send the header along with the data.
