Post by squiggleypuff on RemoteTargetVisu creates Unresolved Reference ^{CODESYS Forge talk (Post)}
I have a project with a Festo CPX-E-CEC-C1-PN PLC (Run-time version 3.5.12.50) that I have been developing on just fine using Codesys V3.5 SP19 Patch 5 (64bit). I am at the stage where I wanted to use the Festo HMI screen, and have added a RemoteTargetVisu object to my application. After adding this object, I am no longer able to log in to the PLC as I get an Unresolved Reference warning for 'USERMGRUSERGETPROPERTY' towards the end of the download process. I was able to find this post (https://forge.codesys.com/forge/talk/Visualization/thread/fc686a6cb2/) where the two possible solutions are to "set the placeholder to emtpy" or update the runtime. Problem is, I don't know how to do either of these things, as I'm still very green in Codesys land. I'd be happy to update the Festo PLC runtime, as that seems like the better option, but have not had any luck in finding a tutorial for this online. If anyone could point me in the right direction I'd appreciate it.

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
This... is not very practical for me - as I have a bunch of different classes - it's just doesn't seems to be very practical to define a NULL for each of them... Something like this I use in parameter definitions. For example: VAR_INPUT refVFD_Drive : REFERENCE TO FB_VFD_Drive := GVL_DUMMY.Dummy_VFD; END_VAR I use this to prepare objects for code I don't control: Typycally visualizations - had many troubles with references set on the fly, right before opening a corresponding visualization... And yes, the instance in GVL_Dummy reports itself as "Fake", so it does not influence the actual application at all. Actually this way I could invalidate a reference, just to set it to a "Dummy" instance.

Post by narius on OPC-UA object instances preexisting in imported xml information model ^{CODESYS Forge talk (Post)}
Hi all, is it possible to use object instances that are not instantiated by codesys itself, e.g. have been defined in UA-Modeler ? When I browse the plc with UA-Expert I see those instances, but I have not seen information in codesys or the web if these are writable in codesys. So far, I am under the impression, that it is not possible, but would like to hear from others. Also, is it correct, that it is not possible to create references inside codesys ? Thanks in advance and kr

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*).

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
Dear all, I've just started to migrate some of my ancient projects to SP20. There is one strange error (?) I have noticed so far. In a method call, depending on the circumstances I would like to return reference to an object, or an invalid reference: METHOD Add_EVT_OUT : REFERENCE TO FB_MSG VAR END_VAR IF __ISVALIDREF(refMSG_Entry) THEN Add_EVT_OUT REF= MANAGER.AddMsg_EVT_OUT( refMSG_Entry, _Get_EVT_Message(MSG_EVENT.OUT), _Get_EVT_AddCode(MSG_EVENT.OUT) )^; ELSE Add_EVT_OUT := 0; END_IF So far setting a reference variable to 0, did this. But now, the expression Add_EVT_OUT := 0; gives an error: [ERROR] DB_WTP_370: Add_EVT_ACK MSG_TRIGGER_EXT: C0032: Cannot convert type 'BIT' to type 'REFERENCE TO FB_MSG' Naturally... I can write: Add_EVT_OUT := DWORD#0; But is this the correct way? Is there any constant I could use instead, like "NULL"? Or this is totally wrong and to be avoided?

Post by manuknecht on Using SMC_MOVTYP.INITPOS without specifying the start position ^{CODESYS Forge talk (Post)}
I am using the object SMC_GEOINFO to generate a trajectory and move a system accordingly using the SMC_INTERPOLATOR function block similar to the sample project CNC10_DynamicPath.project. According to the documentation, the movement type INITPOS does not require a start position in the SMC_GEOINFO object, which is confirmed in the documentation of the SMC_GEOINFO object. When using the movement type INITPOS however, the motion will still start from the starting point defined in the SMC_GEOINFO object (0,0,0 if not specified otherwise). Does someone know how to resolve this or is there an example project that makes use of the INITPOS movement type without specifying the starting point? Thanks in advance!
