I am considering using a SoftMotion cam and tappets to activate functions on a machine - for example, triggering a pneumatic valve. I need the ability to change the actuation point (tappet "X" location) from the HMI during machine commissioning. Is there a way to change the "X" value of a tappet programmatically?

Hi In the POU section of my project I have created a Fan function block and defined an alarm group template for this FB with one alarm (Motor fault). In the PLC program I define two instances of the fan function block. When going to the alarm configuration and pressing "Create or update alarm instances", I get two alarms listed. So far so good. However, when I start my program and check the alarm table in the visualization I only see one alarm, even if both are active. Am I doing something wrong, or is it not possible to define alarms on a function block level and get one set of alarms per instance of the function block?

Thank you for your answer! I know that 0 will be the end of the string. I checked it. There is no 0 in array of bytes. I made screenshots. There is array of bytes, aborted string and the result of my test via online converter.

Yes, There is. As explained "Manual creation of CAM structure" on below section. Likewise tappet structure also can be create manual and value of the switching point can be change during IEC program running. https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_cam_programmatic_creation.html Just create a cam table and define some tapped points as sample for your project. Then on project compile, the created cam tapped data is converted internally into a global variable list. By clicking "Display generated code" in the "cam editor", you can display the automatically created global variables for both cam & tappets. Regards, Imdat

Hi, I have problem with connecting Wago PLC WAGO 750-8212/0025-0002 configured as OPC UA client to Kepware OPC UA Server. I am using Codesys 3.5.19.70. What I did so far. To the Codesys project I added object Data Source Manager and configured connection OPC UA like below: pic 1 Then I can browse the OPC server tags in “Variables” tab after prior trust on the server side of the client certificate created in the “Communication” tab: pic 2 Additionally second certificate has been created in Codesys for runtime process in “Security screen” as well as the server certificate was approved here: pic 3 But when I compiled project, downloaded it to PLC and go to RUN I can’t read selected in “Variables” tab, OPC Server tags. I am getting such error (ID: 7001): pic 4 All two PLC certificates has been trusted in OPC server (Kepware) side: pic 5 and Kepware server configuration look like this: pic 6 I can easily connect using third party OPC UA client UaExpert to Kepware server without problem. In attachment I added also log from Kepware OPC UA server. pic # - this specifies the number of a concrete graphic from one of the collective in attachment

Hello, I have set up an OPC UA server following several guides, including this one: https://revolutionpi.com/documentation/tutorials/opc-ua-codesys-nodered/. The license for the runtime is installed on the device. However, I am unable to create a certificate for the OPC UA server in the security screen. I always get the error message: "The certificate has not been created by the device." Does anyone have an idea what might be causing this issue? Any help would be greatly appreciated! Thanks in advance! Best regards, Stefan
