Post by micik on Python scripting - print whole project tree
CODESYS Forge

(Post)
Hello, I have found a script for printing device tree in Codesys project. This script is available as code snippet as an exmaple for using Python in Codesys. However I feel main documentation is lacking. For example, where can I find that object has "is_device" attribute? Code examples are given here: https://content.helpme-codesys.com/en/CODESYS%20Scripting/_cds_access_cds_func_in_python_scripts.html However, I have a question how to print the whole Project tree and not just devices? Of course I need to remove check: if treeobj.is_device: But simply removing this test condition will not produce what I want. I need to print PLC Logic, Application, ad other nodes in the Project tree. Where to find this documentation?

Hello folks, my problem is a bit bigger for just one question. So let's start with the easiest. But first, my system setup: It's a WAGO 750-8212 PFC with some I/O-modules. I try to communicate with the controlsystem over SNMP using the IIoT library from codesys. https://content.helpme-codesys.com/de/CODESYS%20Examples/_ex_iot_snmp_service.html Is there some expirience with this kind of communication? It's just about transfering some data from PFC to network and setting some analogsettings from network to the PFC. So my easiest question: Do I ever need the SNMP_Agent or can I use the SET / GET function as standalone, without the agent? (maybe some more questions will follow, if someone will answer to my request) thanks so far

Hi, you can call the decoder function block in a loop and/or decrease the task cycle interval of Task_PATH.

Hello Fraziersedge, the solution of Codesys might be to update your codesys to the lastest version but it was not possible for us. In our Codesys V3.5 SP9 patch 8 I was able to fix this bug. I change my ModbusTCP slave component version or one of the sub component version (ex: SysSocket). Look at the picture in attachement that's the receipe that have work for us. When I got the bug my version of ModbusTCP slave was 3.5.5.0 with SysSocket at 3.5.6.0 and I change to ModbusTCP slave 3.5.14.0 with same version 3.5.14.0 of SysSocket event if I still use codesys V3.5 SP9 patch 8.

I want to read and write parameters of an IO-Link device using acyclic messages. I have a Cube67+ in Ethernet/IP, connected to an IO-Link master. In the datasheet, I can find the parameters required for the message (Service, Class, Instance, etc.). I see the function block "Set_attribute_single" in the "EthernetIP Services" library, but I'm not sure how to correctly send the index and sub-index for the IO-Link device. The class in the datasheet is 0x80 for the IO-Link Parameter Object, but it’s not present in the CPIClass enum. Is there another function block more suitable for configuring IO-Link devices? (similar to "iol_call" in PROFINET or what’s used in EtherCAT).

Hello, I have just went through all steps shown on Codesys YT channel https://www.youtube.com/watch?v=RPoPscbo3Kc And it works, I have installed PI OS 32 bit and choose Single Core. However, immediattely when I create standard project with Raspberrz pi device, "Application" is underlined, like there is an error, but in reality there are no errors, and I cannot see what are these 3 messages like shown in attachment. Aside for this red underline, everything seems to work fine. How to correct this? Thank you! Update: I have found what errors are, but not sure how to correct them: Identifier 'IoDrvGPIO' not defined Function block 'IoDrvGPIO' must be instantiated to be accessed 'IoDrvGPIO' is no component of 'IoDrvGPIO'

you can give this code snippet a try. It's extracted and simplyfied from my code: Install VisuElemBase lib if not installed yet. Execute in visu task: VAR pClientData : ARRAY [-1..100] OF POINTER TO VisuElemBase.VisuStructClientData; END_VAR VisuElemBase.g_ClientManager.BeginIteration(); pClientData := VisuElemBase.g_ClientManager.GetNextClient(); WHILE pClientData <> 0 DO pClientData[pClientData^.GlobalData.GlobalClientID] := pClientData; END_WHILE You have to make shure every no longer updated pointers in the array have to be deleted and no longer used by your code! Usage of this pointer access at your own risk :-) Works with SP16. From SP17 and newer there will be warnigs etc. using this solution as I remember. It will be great, if Codesys publishes a example or give a hint how to accesse this client values with the VisuUtil lib or other future-proof way!

Now i am running to problem, when i create instances and i want them to appear directly under the object directory, However, it always appear with me under Objects >> Device set >> Device Name in CODESYS. I need to know how i can change the directory of my instances 'inst_3' and so on. So they can be under objects directly. I tried to modify the settings, but couldn't find any leads till now. Thanks in advance for helping
