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.

I don't fully understand the issue, but if the encoding is a problem you can try testing with WSTRING datatype instead of STRING. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_datatype_wstring.html

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

Post by fabiodasilveira on PLC Shell commands via ST Code ^{CODESYS Forge talk (Post)}
Thank you, Bingo. Your idea of adding the change to the start up process works. However, I am still intrigued with the fact that SysSockSetIPAddress(strEthernetPort:= '0', strIPAddress:= '192.168.2.12') is different from PLC Shell (setipaddr 0 192.168.2.12).:-(

Post by pernockham on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Im looking for a way to define predefined version of the same structures through "extends"/inheritance. What I want to do is best shown with an example: TYPE log_item_val_type : ( BOOL_ := 0, INT_, REAL_, STRING_ ); END_TYPE TYPE LOG_DATA_BASE STRUCT val_type : log_item_val_type; (* value, name etc *) ENDSTRUCT ENDTYPE (* this/below is not possible as I understand from the compiler?? *) TYPE LOG_DATA_BOOL extends LOG_DATA_BASE : STRUCT val_type : log_item_val_type := log_item_val_type.BOOL_; END_STRUCT END_TYPE TYPE LOG_DATA_INT extends LOG_DATA_BASE : STRUCT val_type : log_item_val_type := log_item_val_type.INT_; END_STRUCT END_TYPE etc. for LOG_DATA_REAL and ..STRING. The system will not allow me to "re-define" "val_type" however. Instead I must do the work-around of defining four different types with all fields individually defined. The benefit if I could extend the base item would be that Im (more) sure the structures are identical. In usage I can call in a specific type rather use the base type and assign which type. Usage by pointer/ref to log_data_base would also be easier.. (* Usage: *) log_data : log_data_int := (name, value etc.) (* Instead of: *) log_data : log_data_base := (name, value, val_type).. Is this possible to achieve in some way that I have missed?

Easier that I thought, by ALIAS TYPE log_item_val_type : ( BOOL_ := 0, INT_, REAL_, STRING_ ); END_TYPE TYPE LOG_DATA_BASE STRUCT val_type : log_item_val_type; (* value, name etc *) ENDSTRUCT ENDTYPE TYPE LOG_DATA_BOOL : LOG_DATA_BASE := (val_type := log_item_val_type.BOOL_); END_TYPE TYPE LOG_DATA_INT : LOG_DATA_BASE := (val_type := log_item_val_type.INT_); END_TYPE TYPE LOG_DATA_REAL : LOG_DATA_BASE := (val_type := log_item_val_type.REAL_); END_TYPE TYPE LOG_DATA_STRING : LOG_DATA_BASE := (val_type := log_item_val_type.STRING_); END_TYPE

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!

That's because the array only contains structures themselves, not references. It doesn't matter that what consists of each struectures unless they are not pointers.
