Post by timvh on Get Alarm status in Codesys ^{CODESYS Forge talk (Post)}
You are right, that you can use the GetState method, but it is not that simple. You first have to get a list of (filtered) alarms from the AlarmManager. You can find an example in Forge how to do this. See https://forge.codesys.com/prj/codesys-example/alarm-manager/home/Home/ Then you can go through this list to get the state of all the (filtered) alarms. See below the code which you could use. This is all based on the example from forge. Create a program: // This example shows how to access alarms via structured text. PROGRAM PLC_PRG VAR xInit : BOOL := TRUE; udiResult : UDINT; fbAlarmFilterCriteriaAll : FB_AlarmFilterCriteriaAll; fbAlarmManagerClient : FB_AlarmManagerClient; itfAlarmManagerClient : IAlarmManagerClient := fbAlarmManagerClient; 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; fbAlarmManagerClient.itfAlarmFilterCriteria := fbAlarmFilterCriteriaAll; // register alarm client to get updated about alarm status / changes udiResult := AlarmManager.g_AlarmHandler.RegisterClient(itfAlarmManagerClient, 0, 0); END_IF // Polling the number of alarms udiResult := AlarmManager.g_AlarmHandler.GetActiveAlarms(itfAlarmManagerClient, 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 See below some details about the function blocks: One function block should implement the IAlarmFilterCriteria interface. This can be empty except a few methods. FUNCTION_BLOCK FB_AlarmFilterCriteriaAll IMPLEMENTS AlarmManager.IAlarmFilterCriteria Method implementation (others related to interface are empty) METHOD AreAllAlarmClassesSelected : BOOL AreAllAlarmClassesSelected := TRUE; METHOD AreAllAlarmGroupsSelected : BOOL AreAllAlarmGroupsSelected := TRUE; METHOD GetPriorityFrom : USINT GetPriorityFrom := 0; METHOD GetPriorityTo : USINT GetPriorityTo := 255; The other function block should implement IAlarmManagerClient and get a reference to the FB which implements the IAlarmFilterCriteria FUNCTION_BLOCK FB_AlarmManagerClient IMPLEMENTS AlarmManager.IAlarmManagerClient VAR_INPUT itfAlarmFilterCriteria: AlarmManager.IAlarmFilterCriteria; END_VAR Method implementation (others related to the interface are empty) METHOD GetFilterCriteria : AlarmManager.IAlarmFilterCriteria // see VAR_INPUT for filter GetFilterCriteria := itfAlarmFilterCriteria; Off course you have to add the AlarmManager to your application and add some alarms to it.

Post by alimans on Hex string ^{CODESYS Forge talk (Post)}
Hi kdkwhite, for Word you still can use suggested code by using a union structure and crack down your Word to two byte as bellow: TYPE CrackWordToByte : UNION InWord : WORD; OutBytes : ARRAY [0..1] OF BYTE; END_UNION END_TYPE then define your variable as this type: udInput : CrackWordToByte; now assign your Word variable input to InWord and send OutBytes[x] to the mentioned method: udInput.InWord := WordVariableInput; Input := udInput.OutBytes[x]; Regarding your question about the code: actually 48 is ascii code of "0" and while 65 is the ascii code of "A" so in above code 55 + 10 would be 65.

Post by sumit on Not able to see input data coming from eip adapter on codesys ^{CODESYS Forge talk (Post)}
dhumphries, I changed the datatype this time from BYTE to USINT (because that's what my adapter is sending: array of uint8_t). The text "New Help String" you saw in previous screenshots is just the description of the input/s (it can be anything). I also looked into the logs (see attached) for that ! sign next to the device, I found that connection is being timeout. I tried some suggestions from online such as increase the RPI but still got connection timeout issue, also by changing the datatype, I still don't see incoming data from the adapter, although its visible on wireshark. thanks,
