Post by expertplas on No connection to opc server from codesys opc client ^{CODESYS Forge talk (Post)}
Hello, we have aproblen to connect our CODESYS OPC Client to the OPC Server. We installed the client according the CODESYS manual. We can browse the server and variables can be linked to the PLC. I created a self signed certificate for the CmpOPCUAClent as described. The server has a cerificate also. I copied the certificates to the trusted zone of server and client. But when it comes to data exchange we get an error message. "Communication error in data source OPC UA Library. Error ID : 7001 German : "Kommunikatinsfehler inder Datenquelle OPC UA -Bibiothek. Es wurde kein genauer Fehler angegeben. Fehler ID : 7001" It semms that there is no cerificate exchange. We are working with CODESYS 3.5 SP19 Patch 5. Can anyone here say something about this error or has an idea for a solution? Thanks.

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.

On a PC with the Control Win, this is probably related to the fact that the CAN drivers are not loaded. Go to the folder where your Control Win Configuration file is: - E.g. C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E1FA7ABE - Open the CODESYSControl.cfg - Remove the semi-colon in front of the CAN driver you want to use (section ComponentManager). - Set the component ID to the next number in the list (e.g. Component.8) - Save this file and restart the Control Win.

Post by vformanek on OPCUA Datasource, can not login... ^{CODESYS Forge talk (Post)}
Hello? I have a problem with datasource... I am trying to connect to a OPCUA server. I create a datasource, but I can not login into it. I need to use login credentials to login... Everything works fine in UAExpert, but in codesys I cant seem to get in properly using the login credentials... I have tried to configure the datasource initializer but seem to keep failing... Do I need to call it somewhere ? Will the find endpoints work with this configured to store my password ? !

Post by andrax on Mux I2C ^{CODESYS Forge talk (Post)}
the TCA9548a does not work in Codesys. In Pyton this is only queried once and in Codesys cyclically. Of course you can also insert a terminating resistor in each port, then you should have no problems. I use this one: https://botland.de/8-bit-multiplexer/12723-qwiic-mux-breakout-8-kanal-modul-mit-i2c-multiplexer-tca9548a-sparkfun-bob-16784-5904422341428.html You can simply set the library to the latest version. You do not need Oscat. Do you need an example project for the BMP280?

Post by elektron785 on CAN-Bus in Demo-Version ^{CODESYS Forge talk (Post)}
Hallo, wie verhält es sich mit der Demo-Version und Datenübertragung z.B. via CAN-Bus. Der Bus läuft, das Device befindet sich im Zustand "Operational" aber es werden keine Daten von der Soft-SPS empfangen. Ich benutze aktuell eine nicht lizenzierte Version von CoDeSys Control for Linux ARM64SL. Normalerweise sollte die Demo-Version uneingeschränkt laufen - also kann ich davon ausgehen, dass es sich um einen Programmierfehler handelt oder ist die Feldbusfunktion ohne Lizenz doch in irgendeiner Form eingeschränkt verfügbar (außer dem 30 Minuten Limit nach Reboot)?

Post by tk096 on SMC_Interpolator + SMC_controAxislbyPos ^{CODESYS Forge talk (Post)}
Hi, you can define a start position for your GCode. How the start position can be defined depends on the CompileMode: For File and SMC_CNC_REF: Set the start position input of SMC_NCInterpreter (https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/NC2/Interpreter/SMC_NCInterpreter.html) For SMC_OutQueue: * Right-click on the CNC object in the project tree * Select Properties * Select the tab 'CNC' * Set the start position Concerning your second question: If the new set position cannot be reached with the given velocity limit (AXIS_REF_SM3.fSWMaxVelocity), SMC_controlAxisByPos will report bStopIpo and close the 'gap' with the given gap dynamics (SMC_controlAxisByPos.fGap*).

Hi, I'm trying to get Scaling working on my axis. An increment produces 36.6mm of movement, so I want to put the units in application as 36.6. However the docs say that I need to change bHiresMode as it doesn't show me the option for Precision in the User Interface. I'm thinking that I need to change the precision so I can enter decimal places. How can I do this, or is my thinking wrong? Thanks,

Is it possible to get scroll bars to show when displaying a web visualization in V2.3? I've got some big pages that I can scroll around when using the in-built visualization but when they are displayed in IE i can't seem to scroll around. All I can do it drag the window bigger onto my other display to get access to the extra area. I've also tried zooming the page out in IE but this doesn't seem to work at all.

Post by marcolim on RPC failed 0x16c9a085 ^{CODESYS Forge talk (Post)}
Hello Matteo, I think the problem is about configuration of firewall (windows firewall usually). You can disable temporary the firewall to check if the communication works. Eventually you can: Go to the control panel -> Windows Defender Firewall -> Allow an app or feature Enable the options to change the settings. Scroll down in the application list to CODESYS and CODESYS ControlService. If you don’t see this application add it to the list. Make sure that all the checkboxes are checked (Domain, Private and public).

Post by tk096 on Fieldbus has lost synchronicity ^{CODESYS Forge talk (Post)}
Hi, a few suggestions on how to tackle the problem: - it might help to increase the cycle time of the ethercat task - increase the value of the ethercat parameter DCInSyncWindow (https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/pou-IoDrvEtherCAT/DCInSyncWindow.html) (see attached image) - enable FrameAtTaskStart (https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/pou-IoDrvEtherCAT/FrameAtTaskStart.html) in the ethercat master (see attached image) - if the drives can handle the synchronization problems, checking of the synchronization can be deactivated using SMC_Set_ETC_DCSyncSupervision (https://content.helpme-codesys.com/en/libs/SM3_Drive_ETC/Current/SMC_Set_ETC_DCSyncSupervision.html).

I can add this library but that leaves 2 issues. I don't actually know, and I really want to understand this, why the required dependencies haven't been installed correctly. If I add the library it's only available with through the namespace. What can I do to both understand and resolve this?

Post by timvh on Codesys SVN ^{CODESYS Forge talk (Post)}
If you use 3.5 SP10, then Git is not supported. SVN will work fine, but with this version you do need a USB key, because software licenses are not supported with this version. Off course you can work without SVN (or Git), but especially if you work with multiple developers on one project, it will save you a lot of time and you can keep track of all changes and improvements much easier. So how much is this worth to you?

Hi jonasz, you already solved it, I'm answering here for the sake of others with a similar question. You can provide the slope of the A/B/C axis with the U/V/W word. See example 3 here: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_cnc_din66025_additional_axis.html If you don't want to change the G-Code, the function block SMC_RecomputeABCSlopes can compute the slopes automatically. https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/SoftMotion-CNC/SoftMotion-Function-Blocks/SMC_RecomputeABCSlopes.html Best regards, Georg

Post by ph0010421 on General question about library versions ^{CODESYS Forge talk (Post)}
Hello I can't find anything to read on the subject so I'll ask here. Up to now, when adding a (for example) Modbus Master, I've selected the version <= the RT version, so if I'm using SP13 Patch 3, I can use a library that doesn't exceed this. I've no idea if this is correct, but it's always worked. Can someone explain the 4.x.x.x libraries that have appeared; are they tied to a RT version? The controller I use is now at SP18Patch60, so should I continue to use 3.5.xxx or change? thanks
