Post by rtlman on Scan devices hangs CODESYS ^{CODESYS Forge talk (Post)}
Hello, I have a problem that randomly appeared today. When trying to scan a network adapter in "Deploy Control SL" the whole program hangs and needs to be restarted. I have been running "CODESYS v3.5 SP21 Patch 3" for a while and it has worked without any issues until now. I've tried upgrading to "CODESYS v3.5 SP21 Patch 4" with the same result. I've not made any system settings recently that im aware of which could cause this. Has anybody had similar a issue?

Post by mondinmr on COL.IMap2 and HashTableFactory cause frequent Access Violation ^{CODESYS Forge talk (Post)}
Good morning, I’ve been using the Collection library for a long time, mostly with Stack, LinkedList, and List. From your examples I was able to manage the different factories, even for custom elements. Now I need a hashtable, but with this object I’m running into a lot of random access violations. If I append something inside FB_Init after constructing the hashtable, it crashes, even though the list was already created. If I only create the hashtable in FB_Init and append afterwards, it usually works. I don’t understand the meaning of the dispose call in this code: pSlave := ADR(slave); uSlave := TO_ULINT(pSlave); iKey := fKey.Create(uSlave); IF hash.CountKeys() = 0 THEN Service.logger.appendLog('Filling hashtable', 'HashManager', AdvLogType.AdvDebugMsg); ok := FALSE; ELSE eError := hash.ContainsKey(iKey, xResult => ok); END_IF IF NOT ok THEN pI := __NEW(UINT); iVal := fKey.Create(TO_ULINT(pI)); Service.logger.appendLog(CONCAT('New slave', TO_STRING(uSlave)), 'HashManager', AdvLogType.AdvDebugMsg); hash.AddKeyValuePair(iKey, iVal); appendNewSlave := pI; ELSE eError := hash.GetElementByKey(iKey, itfValue => iElem); xResult := __QUERYINTERFACE(iKey, itfIInstance); IF xResult THEN itfIInstance.Dispose(); END_IF IF eError <> COL.COLLECTION_ERROR.NO_ERROR THEN Service.logger.appendLog(CONCAT('ERROR ', TO_STRING(eError)), 'HashManager', AdvLogType.AdvCriticalMsg); appendNewSlave := nullptr; RETURN; END_IF __QUERYINTERFACE(iElem, iVal); {warning disable C0033} pI := TO___UXINT(iVal.UlintValue); {warning restore C0033} appendNewSlave := pI; END_IF Without the dispose call, every second cold reset crashes immediately when I try to access iVal, even if eError doesn’t report any error. With the dispose call, the cold reset issue disappears, but I get other problems: a) If I start the runtime using systemctl start codesyscontrol, it crashes at IF hash.CountKeys() = 0 THEN b) If I delete the files in PlcLogic and download again, it works and survives multiple cold resets. But as soon as I run systemctl restart codesyscontrol, everything gets corrupted again and it starts crashing at that point. FUNCTION_BLOCK SlaveMapCounter VAR hash : COL.IMap2; eError : COL.COLLECTION_ERROR; END_VAR In its FB_Init I create it: METHOD FB_Init: BOOL VAR_INPUT bInitRetains: BOOL; // TRUE: retain variables are initialized (reset warm / reset cold) bInCopyCode: BOOL; // TRUE: the instance will be copied to the copy code afterward (online change) END_VAR VAR hF : COL.HashTableFactory; END_VAR hash := hF.Create(256); In another FB I instantiate it statically: FUNCTION_BLOCK ABSTRACT AbstractServoEthercatController EXTENDS AbstractServoController VAR_STAT hashSlaves : SlaveMapCounter; END_VAR VAR field : REFERENCE TO ADVAbstractFieldUnitEthercatCia402; initCnt : REFERENCE TO UINT; END_VAR The append method is the one shown above, and I call it after the runtime has started. The accesses are performed by a single task, and in any case I’m working on an isolated single core. I’ve tried everything, moving the create, the instances, and all the rest several times, but nothing seems to work. I’d like to point out that these FBs are part of our own library, which is used in many applications.
