Any resolution on this? I have currently 75 channels in my project that i brought up from SP18, which means i am 65 Channels above the new limitation?

Good morning. I'm working with a Weidmuller controller using Codesys. My project use OPC-UA to communicate an application in my pc with the controller. Yesterday, I installed the license of the controller and test it, and the communication works perfect. I use the communication with anonymous login, and works fine. But, hours later, the anonymous login don't work, and the controller only allows connection via OPC with username and password. Someone know why this happend? Thanks

Hallo liebe Community, im Rahmen einer Studienarbeit gilt es ein OPC-UA-Informationsmodell in eine existierende CODESYS-Steuerung zu implementieren. Dabei sind wir auf die Frage gestoßen welcher Unterschied zwischen den folgenden Objekten besteht: - Symbolkonfiguration (veraltet?) - IEC-Symbolveröffentlichung - Veröffentlichung über zuvor erstelltes Informationsmodell In unserem Verständnis erfüllen alle Objekte die Gleiche Aufgabe nur mit unterschiedlicher Vorgehensweise und Darstellung im OPC-UA-Server. Während durch die Symbolkonfiguration die Variablen und Instanzen über lange und verschachtelte Pfade abgelegt werden, wird durch die IEC-Symbolveröffentlichung ein Ordner im Pfad der Objekte erstellt. Dort sind die Variablen und Instanzen anschließend zu finden. Bei der Verwendung von Informationsmodellen hingegen, werden die Instanzen direkt unter den Objekten abgelegt. Für welchen Anwendungsfall ist welche Vorgehensweise am besten? Vielen Dank vorab und viele Grüße Joel

Post by tecnocons on Trouble Writing Files to External Paths in CODESYS

Hello everyone, I'm encountering an issue in CODESYS regarding writing files to external paths. Despite correctly configuring the placeholder in the CODESYSControl_User.cfg file to allow access to an external folder, CODESYS doesn't seem to write any files, and no errors are reported. The issue on the older versions was absent with no placeholders. I've checked the operating system permissions, and they seem to be in order, but the issue remains. Has anyone faced a similar situation or has any suggestions on how I might resolve this problem? Any help would be greatly appreciated. Thank you in advance for your support. I'm using raspberry PI as a logger. RPI3 Buster Codesys 32bit SL V4.11 Codesys Win64 3.5.20 [SysFile] PlaceholderFilePath.1=/home/pi/scan, $SCAN$

Hello Vincent, I don't have 75 channels but it works for me as described above without any problems. There is also a parameter MAX_MODBUS_CHANNELS in the library parameters for the IoDrvModbusTCP module. The default value there is 100. Perhaps you are reaching the limit there? The value can be adjusted accordingly. I assume that this value is not accepted in the input dialogue and therefore the 'fixed' limit value 10 is used.

The simplest way to do this would be to add a bus coupler dedicated to the expansion IO. The EtherCAT network does not fault when modules connected to the expander are not present. In the image below, nothing below the red line is present in the network - with the network working correctly. In your "base" project, simply include all of the possible modules, and then plug them in as you add pumps to the system. I would also highly recommend against the use of direct addressing. There are other methods to accomplish this, including using the "Optional" checkbox for modules and explicitly addressing them. Although, this would require more upfront work to design the network, and some additional work each time modules were added. https://content.helpme-codesys.com/en/CODESYS%20EtherCAT/_ecat_edt_slave_slave.html
