Post by manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
I have several libraries which contain values that should be saved on a PLC. As apparently no Persistent Variable List is available within Libraries, I use the Persistence Manager to create a Persistence Channel in the Project which imports the library. I then specify the persistence channel in the library using the {attribute 'ac_persist':='PersistenceChannel_CT'} specifier. This generally works very well and gives me exactly the properties I require. However, it came to my attention that the (alphabetially) first value from the library is not saved in the created ASCII file. When checking the content of the Persistence Channel, it shows all the variables as defined in the library. But the created file does not contain the first value and it is not restored after restart or reset. (see attached picture) I disabled Periodic Saving and set xSaveOnChange to TRUE and so the file usually updates immediately after changing one of the values. When changing the first value, it does not update which is consistent with this value not being saved. I also created a sample project and library from scratch which shows the same issue both using a Raspberry Pi and using a Linux machine. Does someone know what the reason for this could be or did someone make similar experiences? Looking forward to hearing your suggestions. Thanks in advance and best wishes Manuel

Post by caprez95 on Trace Restart Visuelement ^{CODESYS Forge talk (Post)}
Hallo zusammen. Ich habe schon länger mit dem Problem zu kämpfen, dass ich einen Trend (Visuelement) nicht resetten (neustarten) kann. Ich habe es jetzt mit dem Beispiel hinbekommen, die Trace-Aufzeichnung über die CmpTraceMgr Bibliothek zu steuern. Aber wie bekomme ich diese Trace-Aufzeichnung in ein Visuelement? Der Code sieht wie folgt aus: // Configure trace IF xInit THEN // Create a trace packet PacketConfig.pszName := ADR('IECTraceConfiguration.Trace1'); // Name of trace PacketConfig.pszApplicationName := ADR('IECTraceConfiguration'); // Name of the application PacketConfig.pszIecTaskName := ADR('Task'); // Name of the task PacketConfig.pszComment := ADR('Demo packet'); PacketConfig.ulEveryNCycles := 1; PacketConfig.ulBufferEntries := 1000; PacketConfig.ulFlags := TRACE_PACKET_FLAGS.TRACE_PACKET_FLAGS_TIMESTAMP_MS AND TRACE_PACKET_FLAGS.TRACE_PACKET_FLAGS_AUTOSTART; IF (NOT fbTraceManager.CreatePacket(PacketConfig := PacketConfig, hPacket=>hPacket1)) THEN xError := TRUE; END_IF // Create a trace record RecordConfig.pszVariable := ADR('iSignal'); // This is the name of variable to record RecordConfig.tcClass := INT_TO_UDINT(TypeClass.TYPE_INT); // Type of the recording variable RecordConfig.ulSize := SIZEOF(iSignal); // Size of the recording variable pApp := AppFindApplicationByName('IECTraceConfiguration', 0); AppGetAreaOffsetByAddress(pApp, ADR(iSignal), ADR(RecordConfig.tvaAddress.taAddress.Area.usArea), ADR(RecordConfig.tvaAddress.taAddress.Area.ulOffset)); // Get and set area offsets RecordConfig.tvaAddress.ulAddressFlags := TRACE_VAR_ADDRESS_FLAGS_IEC OR TRACE_VAR_ADDRESS_FLAGS_AREA_OFFSET; RecordConfig.ulGraphColor := 16#FF00FF00; // green RecordConfig.ulGraphType := 1; // Line with points IF (NOT fbTraceManager.AddRecord(RecordConfig := RecordConfig, hPacket := hPacket1, hRecord => hRecord1)) THEN xError := TRUE; END_IF xInit := FALSE; END_IF // Starts the recording IF xStart THEN IF (NOT fbTraceManager.StartPacket(hPacket := hPacket1)) THEN xError := TRUE; END_IF xStart := FALSE; END_IF // Stop the recording IF xStop THEN IF (NOT fbTraceManager.StopPacket(hPacket := hPacket1)) THEN xError := TRUE; END_IF xStop := FALSE; END_IF // Reset the recording IF xReset THEN IF (NOT fbTraceManager.ResetPacket(hPacket := hPacket1)) THEN xError := TRUE; END_IF xReset := FALSE; END_IF
