Post by dkugler on Webvisu client connection monitoring ^{CODESYS Forge talk (Post)}
you can give this code snippet a try. It's extracted and simplyfied from my code: Install VisuElemBase lib if not installed yet. Execute in visu task: VAR pClientData : ARRAY [-1..100] OF POINTER TO VisuElemBase.VisuStructClientData; END_VAR VisuElemBase.g_ClientManager.BeginIteration(); pClientData := VisuElemBase.g_ClientManager.GetNextClient(); WHILE pClientData <> 0 DO pClientData[pClientData^.GlobalData.GlobalClientID] := pClientData; END_WHILE You have to make shure every no longer updated pointers in the array have to be deleted and no longer used by your code! Usage of this pointer access at your own risk :-) Works with SP16. From SP17 and newer there will be warnigs etc. using this solution as I remember. It will be great, if Codesys publishes a example or give a hint how to accesse this client values with the VisuUtil lib or other future-proof way!

Post by jampid on Struct Literal ^{CODESYS Forge talk (Post)}
Bonjour Davidmic, Il n'est pas possible d'associer une méthode à une fonction. Cela est possible sur les Blocs fonctions. En utilisant ta DUT MyStruct, je créé une fonction avec en entrée un tableau de structure :** FUNCTION F_F3 : REAL VAR_IN_OUT // bien définir un type IN_OUT IN_ptrINT: ARRAY[*] OF MyStruct; // la taille sera définie ultérieurement/ END_VAR VAR _di: DINT; // Index de parcours du tableau pour l'écriture dans les cases ENDVAR ============== //Programme F_F3: FOR _di := LOWER_BOUND(IN_ptrINT,1) TO UPPER_BOUND(IN_ptrINT,1) DO IN_ptrINT[_di].som:=IN_ptrINT[_di].a + IN_ptrINT[_di].b; END_FOR J'utilise ensuite cette fonction dans un POU Programme : PROGRAM Test_F_Fx VAR _aiTAB9:ARRAY[0..3] OF MyStruct := [(a := 1, b := 1.2), (a := 2, b := 2.2), (a := 3, b := 3.3), (a := 4, b := 4.4)]; END_VAR ** ==========** F_F3(IN_ptrINT:=_aiTAB9 ); Voilà l'idée pour avancer. Une autre idée, est d'utiliser les pointeurs ou les références. Bon développement!

Hi, works in my case if I increase the timeout! to_udint(t#100ms) -> 100 -> 100us.. FUNCTION_BLOCK MODBUS_master_example_ST VAR initDone : BOOL := FALSE; aIPAddress : ARRAY [0..3] OF BYTE := [127,0,0,1]; clientTcp: ModbusFB.ClientTcp; // buffer to read input registers aDataInputRegisters : ARRAY[0..9] OF UINT; // some client requests clientRequestReadInputRegisters: ModbusFB.ClientRequestReadInputRegisters; xExecute: BOOL; uistart: UINT := 100; udiTimeout1: UDINT; END_VAR IF NOT initDone THEN initDone := TRUE; // configure clientTcp clientTcp(aIPaddr:=aIPAddress, uiPort:=502, udiLogOptions := ModbusFB.LoggingOptions.All); // configure clientRequestReadInputRegisters clientRequestReadInputRegisters(rClient:=clientTcp, uiUnitId:=1, udiTimeout:=1000000); // 1sec END_IF // call the client FB's clientTcp(); clientRequestReadInputRegisters(rClient:=clientTcp,xExecute := xExecute AND NOT clientRequestReadInputRegisters.xBusy ,uiStartItem:=uistart, uiQuantity:=3, pData:=ADR(aDataInputRegisters[0]));

I'm using the code bellow which is based on the Codesys example: FUNCTION_BLOCK MODBUS_master_example_ST VAR initDone : BOOL := FALSE; aIPAddress : ARRAY [0..3] OF BYTE := [127,0,0,1]; clientTcp: ModbusFB.ClientTcp; // buffer to read input registers aDataInputRegisters : ARRAY[0..9] OF UINT; // some client requests clientRequestReadInputRegisters: ModbusFB.ClientRequestReadInputRegisters; xExecute: BOOL; END_VAR IF NOT initDone THEN initDone := TRUE; // configure clientTcp clientTcp(aIPaddr:=aIPAddress, uiPort:=502, udiLogOptions := ModbusFB.LoggingOptions.All); // configure clientRequestReadInputRegisters clientRequestReadInputRegisters(rClient:=clientTcp, uiUnitId:=1, udiTimeout:=TO_UDINT(T#1000MS)); END_IF // call the client FB's clientTcp(); clientRequestReadInputRegisters(rClient:=clientTcp,xExecute := xExecute AND NOT clientRequestReadInputRegisters.xBusy ,uiStartItem:=2, uiQuantity:=3, pData:=ADR(aDataInputRegisters[0])); As you can see the clientTCP is called cyclically with the same result.
