Post by dvmaris on Control for Linux ARM64-User Management issue ^{CODESYS Forge talk (Post)}
I'm trying to work with Codesys Control for Linux ARM64 SL 4.18.0.0 on a Toradex Verdin NXP iMX8MP. I have the runtime installed and operational as well as Codemeter lite 8.40.7141.503 (arm64). I'm running 3.5.20.60 and when "Scan Network" I see the Verdin popup. When I try to connect to it, the "mandatory use of the user management" popup shows...which makes sense. I click YES and enter user information and click OK. It immediately displays a "No device is responding to the scan request" popup. The IDE can see the Verdin in the scan...so this popup does not make sense to me. I thought maybe it was a read only issue but I've made all partitions and paths RW. Has anyone experienced this? Can anyone tell me where it is trying to write user data?

Post by baotthitawat on Cloud SCADA for Industrial Energy Monitoring ^{CODESYS Forge talk (Post)}
Recently I’ve been exploring ATSCADA iEnergy Tools for SCADA-based energy monitoring systems. One thing I find interesting is how modern SCADA platforms are evolving beyond traditional machine monitoring. Many industrial systems are now using Cloud SCADA architectures for centralized energy management, remote dashboards, and operational analytics. ATSCADA iEnergy Tools supports: Real-time energy monitoring Historical data logging MySQL integration Reporting and Excel export Remote SCADA dashboards Cloud-based monitoring systems I think this type of solution is practical for factories, power monitoring applications, building management systems, and other industrial automation projects where energy optimization is becoming increasingly important. Industrial automation is clearly moving toward web-based and cloud-connected SCADA platforms, especially as more facilities focus on digital transformation and smarter energy management

Post by gseidel on Mismatch between coordinate monitor and actual motion using SMC_GroupJog2, MC_MoveLinearAbsolute (6DOF) ^{CODESYS Forge talk (Post)}
Hi darwin03, as can bee seen at the end of your video, the direction of rotation now seems correct for all axes. I can only guess, but the most likely reason are different denavit hartenberg parameters in the SoftMotion axis group editors and the robot used in the simulation tool. Maybe some arm lengths differ, maybe some offsets are given with opposite sign. I would again refer you to https://content.helpme-codesys.com/en/libs/SM3_Transformation/Current/SM3_Transformation/Function-Blocks/Standalone-Kinematics/Articulated-Robots/6AxisArticulated/Kin_ArticulatedRobot_6DOF.html. Please double check all parameters and the table of the DH parameters given there and compare that against the robot in the simulation tool. Also: did you configure any tool in CODESYS? I would suggest to simplify and remove any tools for finding the source of the wrong movements. Best regards, Georg

Post by struccc on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Strangely reminds me to my struggles... Want to do something "Elegant", reusable, universal, practical... In CODESYS??? 🙃 First of all, before you get too deep into this: If you could find a way, to make a "universal" log entry object, containing the variable length data itself, you wouldn't be able to store them in an array, or access them like an array, or pass them by value as a type. (please correct me, if I'm wrong, incorrect, or not precise). Because... Basically you can't declare a type with variable memory footprint. This is a very deeply embedded characteristic of CODESYS, and all IEC 61131-3 systems, and it has many reasons behind. And yes, it is a very common trap / mistake, to forget about. So, with a log entry - I guess - it's pretty much the purpose: store data and metadata together, and then handle it in a uniform way. There are ways to handle this, really depends on what is the purpose. For example: 1. Entries with fixed length (Maybe it is not as evil as it looks for the first time. Depends on the situation, but definitely the fastest and easiest code) You can have your base object, with an internal, fixed length string or byte array variable. I would go with a string, and call it _Data.; And then you can make properties, like As_Bool, As_Int, As_Real... In the 'set' accessors, you can do like: pReal := ADR(_Data); // POINTER TO REAL As_Real := pReal^; In the 'get' accessors, evidently: pReal := ADR(_Data); // POINTER TO REAL pReal^ := AS_Real; Or, can use ANY type, if you are not obsessed with variable / property like access: 2. Fixed length, but nicer First, some disadvantage to any values: - You can only assign values with write access. No literals, constants, etc... - Can only be used as input variable of function or function_block - Therefore, stg you could reach: LogEntry.Initialize (stVariable|rVariable|iVariable|xVariable); Just a quick example (it's funny to play with ANY): Be careful it was not tested. I'm sure can be done better, please feel free to comment FUNCTION_BLOCK FB_LogEntry VAR_INPUT MsgClass : UDINT; // Like DEBUG, WARN, ERR... MsgCode : UDINT; // Like Errors.ERR_FAILED MsgTS : DT; // The timestamp END_VAR VAR _Data : STRING(80); // Our data container... _Descr : __SYSTEM.AnyType; // A standard descriptor for our data, containing TYPE_CLASS, address and size END_VAR METHOD SET_Value : BOOL VAR_INPUT anyValue : ANY; END_VAR VAR I : DINT; diSize : DINT; pStr : POINTER TO STRING; END_VAR // Check what did we receive in anyValue. diSize := anyValue.diSize; // We use constant __SYSTEM.TYPE_CLASS to identify the received data type CASE anyValue.TypeClass OF // Maybe we don't want to store references, pointers... and who knows what else... __SYSTEM.TYPE_CLASS.TYPE_REFERENCE, __SYSTEM.TYPE_CLASS.TYPE_POINTER : SET_Value := FALSE; // For the planned types we will be just fine. TYPE_CLASS.TYPE_BOOL, TYPE_CLASS.TYPE_INT, TYPE_CLASS.TYPE_REAL : SET_Value := TRUE; // Optionally string can be handled separately, maybe we have received STRING(255), but practically it is shorter than 80 bytes... TYPE_CLASS.TYPE_STRING : pStr := anyValue.pValue; diSize := MIN(anyValue.diSize, LEN(pStr^) + 1); // Get the actual size, and rewrite the received structure member diSize := MIN(SIZEOF(_Data), diSize); // Can chop down the received string to our length... SET_Value := TRUE; // Maybe want to play a little bit more here, to narrow down or convert datatypes, etc... // Or just reject any other datatype ELSE SET_Value := FALSE; RETURN; END_CASE // Fail, if the received value is still larger than our container... IF diSize > SIZEOF(_Data) THEN SET_Value := FALSE; END_IF // Here we should be ok, just set up the _DataType structure, and copy store the data IF SET_Value THEN THIS^._Descr.TypeClass := anyValue.TypeClass; // The typeclass is already filtered THIS^._Descr.diSize := diSize; // Set the (adjusted) size THIS^._Descr.pValue := ADR(_Data); // This will not change, just to be sure {IF defined (pou:SysMem.SysMemCpy)} SysMem.SysMemCpy(_DataType.pValue, anyValue.pValue, TO_UDINT(anyValue.diSize)); {ELSE} // An ugly replacement MemCpy FOR I:=0 TO diSize - 1 DO _Descr.pValue[I] := anyValue.pValue[i]; END_FOR {END_IF} // Otherwise, in case of failure maybe better set an empty value (overwrite the former data descriptor) ELSE THIS^._Descr.TypeClass := TYPE_CLASS.TYPE_NONE; THIS^._Descr.pValue := ADR(_Data); THIS^._Descr.diSize := 0; END_IF METHOD GET_Value : BOOL VAR_INPUT anyValue : ANY; END_VAR VAR I : DINT; END_VAR // We just have to serve the data, using the __System.AnyType structure received // Roughly we can say: IF anyValue.TypeClass = _Descr.TypeClass AND anyValue.pValue <> 0 // This should not be possible, already taken care of by Codesys (?) THEN {IF defined (pou:SysMem.SysMemCpy)} SysMem.SysMemCpy(anyValue.pValue, _DataType.pValue, TO_UDINT(MIN(anyValue.diSize, _Descr.diSize))); {ELSE} // An ugly replacement MemCpy FOR I:=0 TO MIN(anyValue.diSize -1, _Descr.diSize - 1) DO anyValue.pValue[I] := _Descr.pValue[I]; END_FOR {END_IF} // Just to make sure, that our string is terminated... IF anyValue.TypeClass = TYPE_CLASS.TYPE_STRING THEN anyValue.pValue[anyValue.diSize -1] := 0; END_IF GET_Value := TRUE; RETURN; END_IF // ... But can play more CASE anyValue.TypeClass OF TYPE_CLASS.TYPE_WSTRING : ; // Could do conversion TYPE_CLASS.TYPE_XSTRING : ; // Wow, I have to figure this out TYPE_CLASS.TYPE_PARAMS : ; // BTW, what is this, how to use? TYPE_CLASS.TYPE_ANYNUM : ; // ... END_CASE Be careful it was not tested. I'm sure can be done better, please feel free to comment 3. If you really want to do entries with variable size In a standard environment, it would be similar to the previous, except you dont have the container variable _Data, just use a pointer, practically _Descr.pValue At Initialize (SET_Value), you have to allocate the memory, would be easy with SysMem.SysMemAlloc - nowadays with SysMem.SysMemAllocData -, and you make sure to release it after use with SysMem.SysMemFreeData... SysMemAlloc was already hidden. The problem with this, that sooner or later your application will totally fragment the dynamic memory, and fail... So should look for some form of dynMaybe MemUtils.MemoryManager (I am not sure what is the status and the future of it). 4. You will end up by a LogEntry Factory ... 5. You could still have a look at this IEC Snippets BTW, Standard Codesys Logger is not a bad choice either. If you are really interested, I share some more code / library.

To prevent ambiguous use of this enumeration value. Let's say another ENUM is available in your project or in another library which has an enumeration value AM_WRITE, then it is not clear which AM_WRITE you want to assign. By this qualified access to the SysFile.AM_WRITE, it is completely clear for the compiler.
