Post by paro on Modbus Client Request Not Processed ^{CODESYS Forge talk (Post)}
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.

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!
