Same for me. I have problems with UAExpert too. Can't see the Current Value of Enum and can't control. Did some Tests with Python opcua library. Not working with the communication manager so far.

Post by rckalex on Changing Trace Variable at Runtime ^{CODESYS Forge talk (Post)}
Is it possible to change the variable being traced during runtime? I would like to use the CURRENTCLIENTID in combination with an array of real numbers to alter the traced variable in a display window, without needing to create separate visualizations for each variable.

Post by timvh on Device diagnosis ( EtherCAT IO card ) ^{CODESYS Forge talk (Post)}
You can get the state by just using the name of your node (same name as in device tree): VAR etcState: IoDrvEthercatDriverLib.ETC_SLAVE_STATE; END_VAR etcState := EJ1100.wState; Alternatively, you can iterate through the device tree to get the status of all (Ethercat) nodes. See here an example (no guarantee it works, just give as suggestion): PROGRAM P_IO_State VAR CONSTANT uiMAX_NR_OF_TERMINALS : UINT := 100; END_VAR VAR // general device diagnosis // can only be used when the Device - PLC Settings - Advanced settings - enable diagnosis for devices is enabled // this will add the DED library coupler: DED.INode; terminal: DED.INode; aDeviceState: ARRAY[0..uiMAX_NR_OF_TERMINALS - 1] OF DED.DEVICE_STATE; uiTerminalCount : UINT; uiIndex : UINT; // for each terminal check if it implements device diagnostics xQueryResult: BOOL; itfDevice : DED.IDevice2; xDiagAvailable: BOOL; eError: DED.ERROR; xEverythingOK: BOOL; END_VAR uiTerminalCount := 0; // start at the top of the device tree with the first EtherCAT coupler coupler := EtherCAT_Master.FirstChildNode; WHILE coupler <> 0 DO // for each coupler that is found start at the first terminal terminal := coupler.FirstChildNode; WHILE terminal <> 0 AND uiTerminalCount < uiMAX_NR_OF_TERMINALS - 1 DO // for each terminal that is found get the status through the device diagnosis interface xQueryResult := __QUERYINTERFACE(terminal, itfDevice); IF xQueryResult THEN aDeviceState[uiTerminalCount] := itfDevice.GetDeviceState(xDiagnosisInfoAvailable => xDiagAvailable, eError => eError); uiTerminalCount := uiTerminalCount + 1; END_IF terminal := terminal.NextSiblingNode; END_WHILE coupler := coupler.NextSiblingNode; END_WHILE uiIndex := 0; xEverythingOK := TRUE; WHILE uiIndex < uiTerminalCount DO IF aDeviceState[uiIndex] <> DED.DEVICE_STATE.RUNNING THEN xEverythingOK := FALSE; EXIT; END_IF uiIndex := uiIndex + 1; END_WHILE

Solution: VAR itfAlarmConfig: AlarmManager.IAlarmConfiguration; itfAlarmConfig7: AlarmManager.IAlarmConfiguration7; SCRIPT itfAlarmConfig := AlarmGlobals.g_AlarmHandler.GetAlarmConfiguration(0); IF __QUERYINTERFACE(itfAlarmConfig, itfAlarmConfig7) THEN itfAlarmConfig7.ClearHistory(FALSE); END_IF Works perfectly for me.

For a permanent change, you may need to update the PLC configuration file or set the IP at startup using retained variables.

Post by pernockham on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
Started playing with the idea of ditching windows for linux, one of the obstacles would be Codesys development. Alternatives: - linux with wine? - Run windows/codesys through virtual machine I guess a vm is the way to go? Anyone out there that could share their experience?

Hello, You can create a program in ST for AS228T using either DELTA ISPSoft or DELTA DIADesigner. The only DELTA PLCs/Controllers I know of compatible with CODESYS are AX-3 and AX-8 series. You will need to install the proper packages, though. Cheers!

@eschwellinger - We are experiencing the exact same issue. RunTime 3.5.19.70 and IDE V3.5 SP21. It's 100% reproducible. All you have to do is disconnect the network cable for about 10 minutes. OPC UA Crashes and requires a reboot to fix.
