Post by yannickasselin on Connect to remote PLC via local pc and teamviewer ^{CODESYS Forge talk (Post)}
Yes it is possible. I did it a lot of times using TeamViewer VPN. Unfortunately, TeamViewer VPN only works on Windows. If the remote PLC is a Codesys runtime running on Windows, you should be able to login directly using TeamViewer VPN if it is installed on the PC/PLC. If it is not Windows based, you can still do it but you need to have a Windows based PC acting as a gateway in the middle. In this case you need to enable IP Forwarding on the Windows remote PC (the gateway) and you need to setup the gateway IP address on the PLC to be the address of the Windows PC. Then you need to add a route on your local PC to point to the gateway PC for Codesys communication. I know it may not be detailed enough but I did not want to make a whole tutorial on how to do it. Bottom line, it is possible. I do it all the time.

Post by phoward131 on Alarm State Icon ^{CODESYS Forge talk (Post)}
I am trying to create an icon on an overview screen that depicts if an alarm group has active alarms, active acknowledged alarms, or inactive unacknowledged alarms (waiting for confirmation). I've attempted to set up Notification Actions in the Alarm Class to set variables based on state changes but have been unable to find a clean and effective way to do this. Because an action on any alarm will trigger the variable to be set as instructed, I'm struggling to find a way to configure it for what I need (ie if two alarms activate, then one deactivates, the variable for indicating an alarm is active would be cleared after the single deactivation). I've been pointed toward the Alarm Manager example project but I'm finding it too complicated to understand how to implement it in my own project. Has anyone come up with another good way to indicate the states of alarms or a simpler usage of the Alarm Manager functions?

Post by leandroct on Error reading files after runtime update from 4.0.0.0 to 4.8.0.0 ^{CODESYS Forge talk (Post)}
Since version 19 they changed how file access is handle. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2. You can, if you don´t want to store at PlcLogic, add the following line in the CODESYSControl.cfg under [SysFile]: ForceIecFilePath=0 The CodesysControl.cfg is at C:\ProgramData\CODESYS\CODESYSControlWinV3x64\xxPROJECT_NUMBERxx\ Here the email they sent me: "with the 3.5.19 Version we changed how files are handled. See following issue: CDS-81506 - CODESYS Control SysFile system file access vulnerability. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2. You can, if you don´t want to store at PlcLogic, add the following line in the CODESYSControl.cfg under [SysFile]: ForceIecFilePath=0 Here is the official release-note: [[COMPATIBILITY_INFORMATION]] With the activation of ForceIecFilePath the file access from IEC is now restricted to the configured paths only (file sandbox)! [SysFile] ForceIecFilePath=1 (new default) The standard path is the current directory, the PlcLogic subfolder or a configured path. Every file access outside of this path is configured via PlaceholderFilePath, for example access to temporary files or removable media: [SysFile] PlaceholderFilePath.1=/tmp, $TMP$ PlaceholderFilePath.2=/media/usb, $USB$ PlaceholderFilePath.2.Volatile=1 For more information see our tutorial FilePath & Placeholders. To restore the old behavior ForceIecFilePath may be configured as follows: [SysFile] ForceIecFilePath=0 BUT WE HIGHLY RECOMMEND TO LEAVE THIS SETTING AT ITS NEW DEFAULT VALUE! "

Post by caprez95 on Trace Restart Visuelement ^{CODESYS Forge talk (Post)}
Hello everyone. I've been struggling with the problem for a long time that I can't reset (restart) a trend (visual element). With the example I have now managed to control the trace recording via the CmpTraceMgr library. But how do I get this trace recording into a visual element? The code looks like this: // 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
