Thanks. But my goal is to get files from PLC to PC, and use PC as initiator of this data transfer. In my application I would like to use python script to do all the work, like get files and then work with them. Firstly I was thinking about ftp, because in CXA_SocketComm documentation is mentioned this: It should mean that there is running server. Also when I tried to connect to it with FileZilla client it says "Connection refused by server", so if I am not mistaken, than there is some server running, no? But I didn't find any way, how to connect to it and use it. So shouldn't it be possible to initiate file transfer from some PC client or server? The other way is to use WebDAV. I setup connection between CtrlX CORE and Windows PC via Map network drive as mentioned in the topic mentioned below. Then I am able to work with files directly. https://developer.community.boschrexroth.com/t5/ctrlX-PLC/Accessing-Logfile-on-ctrlX-with-tail-program/m-p/53116 I don't have much experience with WebDAV yet. Is that connection stable? Is that good way to get files from PLC, or is there better way? Thanks.

Hello, I am trying to get .bin files from PLC to PC. Currently I can do so with usage of FB IL_FTPPutFileAsync (from CXA_SocketComm library). Which means initiate data transfer from PLC (client) to PC (server). But my question is, is it possible to initiate data transfer from PC (specifically with Python)? Should it be possible with FTP or with WebDAV e.g.? I have read a lot of similar topics so sorry for asking question again, but I haven't found clear answer for initiating that kind of data transfer from PC. Thanks a lot for your support.

Hello @Sgilk, You were right. In the program we are watching Error bit from AxisInterface (arAxisStatus_gb[Axis_XA.AxisNo].Diag.Error), and at the time Error becomes TRUE, diagnostic NumberMain and NumberDetail (arAxisStatus_gb[Axis_XA.AxisNo].Diag.NumberDetail) are reset and written to AxisStatus structure as 0000 0000 and after delay between 100-250ms set as required (e.g. 091F2002). I was not counting with that delay and because of that behavior I think it's not possible to implement DiagNumbers as latch variable to Error message in Alarm management.

Hello Comunnity, We are currently finalizing project for our customer and we face some strange behavior of Alarm management in Codesys Webvisu. @PADE To specify detailed information about error we use LATCH variables. (Fig.1) Those LATCH variables are filled in from our program as soon as error is triggered. (Fig.2) But problem is that most of the times (not every time) the Latch variables are shown as „0000000“ instead of string in variable. (Fig.3) It gets even more strange when one Latch variable is "IPO 090F2002" (Fig.4). In alarm table it is shown as "IPO 00000000 00000000" (Fig.5), it looks like it takes in count only the first part of the string. Have you encountered this behavior before? Do you have any hints? Thanks and best regards.

Hi everybody, I am recently experimenting with Python scripting in PLC Engineering, and wondering if there is any python library to navigate through Objects(System, projects, etc.) more easily? For example instead of studying the object "path" e.g. system.ui.choose() step by step from CODESYS Scripting Engine online help, just to type . and have access to some suggestions as usual. I think it would make programming much faster. Kind regards
