Post by rafael on Wbm/runtime and visualization login ^{CODESYS Forge talk (Post)}
Hello everyone, I’m trying to understand if it is this way or I can change it. I’m making a PLC code and visualization screens, the ideia is to operate via webvisu some controls. So i made a code, made some screens and when i try it in my web browser, first it asks me to insert te user and password of the wbm/runtime of the plc (user: admin, password: wago by default), then i can acess my screens but I have to login again with the user and password that i created in the visualization user managment. My question is: is there a way to disable this first login to the visualization screens (webvisu)? Or create another user/password for this first screen? I have a PFC200 and a Edge Controller, both are working the same way. Thanks in advance Thanks

Post by sachem on SysFileGetTime problem ^{CODESYS Forge talk (Post)}
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

Post by sachem on Problem retain values Weidmuller UC20-WL2000 ^{CODESYS Forge talk (Post)}
Good afternoon. I am working with a weidmuller uc20-wl2000 controller, using a codesys license. We made a ladder code to control a process, and it works well, but we want some variables to remain stored even when the controller is turned off. We tried to use retain variables, but at the time of loading the program, when we went offline from the controller, the program was deleted, it did not remain in the controller, and in the same way if we turned off the controller. In addition to this, when we tried to program it again, the program would not stay loaded and began to present errors with the opc-ua communication. What could be causing this problem? How can we maintain the values of the variables without damaging the program or affecting the controller? thank you

I detect a Bug of Codesys....NO WORK AUTOMATICALLY RESTARSLAVES. I explain the secuence: I have click in my project the option AUTOMATICALLY RESTARSLAVES In the moment start my Ipc, the network ethercat start correctly I disconnect the wire of my first slave and later connect again the wire..(see the screen Bug Codesys restart slave1) NO work the restart automatic slaves...and is not possible execute of FB MC_REset beacuause appear this error (see the screen Bug Codesys restart slave2) The only way for resolver this problem is execute the FB SMC3ReinitDrive I replay the same with PLC BECKHOFF in Twincat3 and I havent this problem...In the moment connect the wire again in the slave the comunication of ehterCat restart and the slave comunication again with out problem

Post by tk096 on gear over gear (2 masters,1 slave) - how to do it? ^{CODESYS Forge talk (Post)}
Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

Post by iliyatsukerman on SoftMotion auf PFC200 ^{CODESYS Forge talk (Post)}
Hallo, Wir würden Ihre Unterstützung bei der Überprüfung der Kompatibilität der folgenden Konfiguration sehr schätzen: • PSTR-LO-16/400FEV ELMO • SCALANCE XC208 • WAGO PFC200 750-8213/40-010 • Die SPS (WAGO) wird gleichzeitig eingesetzt als: o EtherCAT-Master zur Kommunikation mit einem Elmo-Servoantrieb (EtherCAT-Slave, 4 Achsen – generisches CiA 402-Profil), und o Modbus-TCP-Server zur Kommunikation mit einem Siemens Modbus-TCP-Client, welcher zur Fernsteuerung des Elmo-Servoantriebs über die SPS dient. Bitte bestätigen Sie, ob die SPS in der Lage ist, diese Dualfunktion — als EtherCAT-Master und gleichzeitig als Modbus-TCP-Server — ohne Konflikte oder Performanceprobleme zu unterstützen. Insbesondere interessiert uns, ob die CODESYS SoftMotion SL Basislizenz (2305000000-F) notwendig ist, um 4 Servoachsen zu steuern, und ob diese Lizenz auf einer WAGO PFC200 SPS mit CODESYS Version 3.5 Service Pack 19 Patch 40 oder höher unterstützt wird. Alle Achsen im Servoantrieb werden unabhängig voneinander gesteuert. Mit freundlichen Grüßen. ILIYA

The Epis controller should support the CodeMeter driver to be able to access the license containers on the CODESYS Key.

Post by amani on PN Controller auf Raspberry Pi 4 ^{CODESYS Forge talk (Post)}
Hallo zusammen, Ich mache +/- erste Schritte mit RaspberryPi und Codesys: tolle Sache! Ich habe Codesys V3.5 auf einem Raspberry Pi 4 am laufen. Ich würde damit gerne einen Profinet-Slave bedienen. Die Kommunikation läuft, nun habe ich das Problem dass ich nicht verstehe wie ich den PN-Task mit dem PLC task synchron halte: Ich muss dem Slave eine Parameter-ID übergeben und beim nächsten Zyklus die Antwort auslesen. Da es dann mehrere Parameter gibt die ich nur sequentiell auslesen kann benutze ich also einen Zähler der mir die ID's durchstept. Aktuell sieht es aus als ob dieser Zähler schneller inkrementiert als der Slave antwortet (ich habe z.Bsp. 5 Parameter, diese zeigen dann alle das gleiche oder springen zwischen den Parametern). Also kurz gesagt ich muss sicherstellen dass die Datenbytes vom Slave zur gesetzten Parameter-ID passen... Ich wäre froh um ein paar Tipps! Herzlichen Dank! Grüsse, Stephan A. Wicki

Add existing version (with SM drive) - without scan - disable under expert settings in the slave the revision check.

An ENI file is needed for a 3rd party software solution that is being used over EtherCAT connection that emulates multiple Slave devices. This one cant be that complex, seen some legacy posts but no answers. Thank you! Bruce
