Post by talhaali on Alarm status in logic ^{CODESYS Forge talk (Post)}
Hi, I am trying to access active alarms in code(As alarm count variable updates only when we go to to alarm table frame in visualization). I wrote following code but it is not working: VAR iCountActiveAlarms : INT; parritfActiveAlarms : POINTER TO ARRAY[0..0] OF IAlarm; itfAlarmManagerClientAll : IAlarmManagerClient; END_VAR AlarmManager.g_AlarmHandler.GetActiveAlarms( itfAlarmManagerClient :=itfAlarmManagerClientAll, iCountActiveAlarms => iCountActiveAlarms, parritfActiveAlarms => parritfActiveAlarms); The Value is always 0. Please help.

Hi, Codesyscontrol 4.13.0.0 Raspberry Pi5 64bit with latest updates. Cant get working GPIO - no output and no input. SPI/I2C not tested. GPIOs B+/Pi2, Input/Output is set in the parameters, assigned variables int the Mapping. Absolutely no reaction. Do I need to configure anything else to make it work? Thanks!

Nice puzzle for a Saturday afternoon :-). Here my suggestion: VAR sInput : STRING := 'R123'; byChar : BYTE; sOutput : STRING; i: INT; END_VAR sOutput := ''; IF LEN(sInput) = 0 THEN RETURN; END_IF FOR i := 0 TO LEN(sInput) - 1 DO byChar := sInput[i]; sOutput := Concat(sOutput, TO_STRING(byChar)); END_FOR

Post by davidmic on Struct Literal ^{CODESYS Forge talk (Post)}
Hi all I want to pass a struct into a function without declaring the struct in a VAR/END_VAR. Is this possible? I think this would be called a struct literal It would look something like this someFB.write(structArgument := MyStruct#(a := 1, b := 1.2), otherArgument := TRUE); With this struct declaration TYPE MyStruct : STRUCT a : INT; b : REAL; END_STRUCT END_TYPE

Post by benemenn on Type mappings in Datasource ^{CODESYS Forge talk (Post)}
Hi! I am trying to achieve the same issue. Has there been a solution? I can create the mapping, and map the local variable, but somehow the object does not update. Furthermore, i have an issue where codesys doesn't let me set ReadWrite accesses to the variables in the "Type Mapping" place. The access will simply not be set. Has anyone ran int that issue?

Post by timvh on Management of a PLC network from a remote station ^{CODESYS Forge talk (Post)}
Maybe the CODESYS HMI is a good solution. https://store.codesys.com/en/codesys-hmi-sl-bundle.html Run this on the remote main control station. In the HMI application you can add the data source manager and to this manager you can add Data sources. A data source has a reference to the PLC you want to connect to and can get access to the variables of the PLC application. You can then use these variables in the visualization of the HMI application.

Post by respl on IFM EXOR Network variable Error ^{CODESYS Forge talk (Post)}
We are connected IFM CR711S to Exor EX710. We are exchanging data using network variables. Both devices are configured on same project so no need to use file source. When tested application it works fine. But after 3 months same application not working. We are able to send data from CR711 to EX710 but data from Ex710 to CR711s works only for one scan when we cold reset CR 711S. Can somebody help to find out error.

See https://forge.codesys.com/forge/talk/Engineering/thread/280fdf4806/#9fe5 And https://forge.codesys.com/prj/codesys-example/alarm-manager/home/Home/ The application should contain: - an FB which implements AlarmManager.IAlarmFilterCriteria (see example - FB_AlarmFilterCriteria) - an FB which implements AlarmManager.IAlarmManagerClient (see example - FB_AlarmManagerClient) Then register the client and get the information through this client. VAR xInit : BOOL := TRUE; udiResult : UDINT; fbAlarmFilterCriteriaAll : FB_AlarmFilterCriteria; fbAlarmManagerClientAll : FB_AlarmManagerClient; itfAlarmManagerClientAll : IAlarmManagerClient := fbAlarmManagerClientAll; xAlarm1 : BOOL; xAlarm2 : BOOL; xWarning : BOOL; iNrOfAlarmsInAlarmList : INT; iNrOfActiveAlarmsInAlarmList : INT; paitfAlarm: POINTER TO ARRAY [0..0] OF AlarmManager.IAlarm; iAlarmIndex : INT; eAlarmState: AlarmManager.AlarmState; END_VAR IF xInit THEN xInit := FALSE; fbAlarmManagerClientAll.m_itfAlarmFilterCriteria := fbAlarmFilterCriteriaAll; // register alarm client to get updated about alarm status / changes udiResult := AlarmManager.g_AlarmHandler.RegisterClient(itfAlarmManagerClientAll, 0, 0); END_IF // Polling the number of alarms udiResult := AlarmManager.g_AlarmHandler.GetActiveAlarms(itfAlarmManagerClientAll, parritfActiveAlarms => paitfAlarm, iCountActiveAlarms => iNrOfAlarmsInAlarmList); iAlarmIndex := 0; iNrOfActiveAlarmsInAlarmList := 0; WHILE iAlarmIndex < iNrOfAlarmsInAlarmList DO eAlarmState := paitfAlarm^[iAlarmIndex].GetState(); IF eAlarmState = AlarmManager.AlarmState.Active OR eAlarmState = AlarmManager.AlarmState.ActiveAcknowledged THEN iNrOfActiveAlarmsInAlarmList := iNrOfActiveAlarmsInAlarmList + 1; END_IF iAlarmIndex := iAlarmIndex + 1; END_WHILE

Post by pjoret on IFM CR711S Can Low Level Library Use ^{CODESYS Forge talk (Post)}
Hello, I'm using CR711S from IFM and I would like to use the CAA Can Low Level in de Safety part. I already use it on the Standard part and it works properly. I would like to know if there is some restriction on using it on the safepart of the PLC (I tried but my PCL put himself in Stop...) ? And if you have some example or even a forum with some types on IFM and CoDeSys, I would Take It. Have a nice Day.

Hi, sorry I can´t help you with your issue, but I hope you can give me a hint on getting GUID for other objects than POUs. Your code states "Guid("6f9dac99-8de1-4efc-8465-68ac443b7d08")". We can I find the GUID / ObjectIds`? I wasn´t able to get details about the GUID of DataTypes (STRUCT/ENUM,..)m, Functions (FUN), GLOBALS and TYPES. I want to create markdown of all available project elements. Thanks for your help
