Post by scoob on ModbusFB - Slow Response Time ^{CODESYS Forge talk (Post)}
Hello, I have been trying to use the ModbusFB functions so I can put some code into libraries, but it seems to be very slow for me. I have a Modbus device with 100ms registers. I previously setup 10 channels in the 'traditional' Modbus Slave with channels and mappings - and set a cyclic trigger at 100ms - this worked fine. I then tried the ModbusFB example, and setup reading the same 10 blocks of modbus addresses, copying the example and putting all of the requests into an array and triggering the requests sequentially. I timed how long the requests are taking to get round to each one, and it is around 1s 450ms. How do I speed this up to match the cyclic time? IF NOT(init) THEN init := TRUE; // Set the required IP address: ipAddress[0] := 192; ipAddress[1] := 168; ipAddress[2] := 1; ipAddress[3] := 10; // Pass the required IP address to the clinet FB: client_NetworkSwitch.aIPaddr := ipAddress; client_NetworkSwitch.udiLogOptions := (ModbusFB.LoggingOptions.ClientConnectDisconnect OR ModbusFB.LoggingOptions.ClientReceivedValidReplies); // Try to connect the client client_NetworkSwitch(xConnect:=TRUE); // Configure all the channels to read connecting them to the client: portStatus_Request(rClient := client_NetworkSwitch, uiStartItem := 4096, uiQuantity := 32, pData := ADR(portStatus), udiReplyTimeout := udiReplyTimeout); portSpeed_Request(rClient := client_NetworkSwitch, uiStartItem := 4352, uiQuantity := 32, pData := ADR(portSpeed)); flowControl_Request(rClient := client_NetworkSwitch, uiStartItem := 4608, uiQuantity := 32, pData := ADR(flowControl)); linkUpCounter_Request(rClient := client_NetworkSwitch, uiStartItem := 5888, uiQuantity := 32, pData := ADR(linkUpCounter)); txPacketCounter1_Request(rClient := client_NetworkSwitch, uiStartItem := 8192, uiQuantity := 100, pData := ADR(txPacketCounter1)); txPacketCounter2_Request(rClient := client_NetworkSwitch, uiStartItem := 8292, uiQuantity := 28, pData := ADR(txPacketCounter2)); rxPacketCounter1_Request(rClient := client_NetworkSwitch, uiStartItem := 8448, uiQuantity := 100, pData := ADR(rxPacketCounter1)); rxPacketCounter2_Request(rClient := client_NetworkSwitch, uiStartItem := 8548, uiQuantity := 28, pData := ADR(rxPacketCounter2)); txErrors_Request(rClient := client_NetworkSwitch, uiStartItem := 8704, uiQuantity := 64, pData := ADR(txErrors)); rxErrors_Request(rClient := client_NetworkSwitch, uiStartItem := 8960, uiQuantity := 64, pData := ADR(rxErrors)); // Trigger all client requests initially FOR clientRequestsCnt := 0 TO (SIZEOF(clientRequests)/SIZEOF(clientRequests[0]))-1 DO pClientRequest := clientRequests[clientRequestsCnt]; pClientRequest^.xExecute := TRUE; END_FOR // Prepare sequential trigger / control of client requests. clientRequestsCnt := 0; pClientRequest := clientRequests[clientRequestsCnt]; END_IF // Call the client to do request processing: client_NetworkSwitch(); // Now we trigger client request sequentially ... IF NOT pClientRequest^.xExecute AND NOT pClientRequest^.xDone AND run AND client_NetworkSwitch.xConnected THEN pClientRequest^.xExecute := TRUE; END_IF // .. and check result/error IF pClientRequest^.xExecute AND run AND client_NetworkSwitch.xConnected THEN IF pClientRequest^.xDone THEN // Prepare next trigger of client request (a rising edge of xExecute) pClientRequest^.xExecute := FALSE; IF clientRequestsCnt < SIZEOF(clientRequests)/SIZEOF(clientRequests[0])-1 THEN // next client request clientRequestsCnt := clientRequestsCnt + 1; ELSE clientRequestsIterationCounter := clientRequestsIterationCounter + 1; clientRequestsCnt := 0; END_IF pClientRequest := clientRequests[clientRequestsCnt]; END_IF END_IF I did try a semi-coded way using the IoDrvModbusTCP library, and setting the slave com settings, then 10 commands and 10 requests, then using a TP on xDone as a pause, before triggering another request - this is time the delay is around 120ms - so the device is fine with the speed, just something I am doing wrong in the ModbusFB method I am sure.

Post by k2saki on CNC / G01 Speed is very slow (or go-stop motion) in Continuous short segment . ^{CODESYS Forge talk (Post)}
I'm using CAD/CAM that outputs GCode with G01 many short segments from NURBS Curve, only X-Y axis. But CODESYS CNC motion seems much slower ( or stop-go motion ) in simulation mode than F-Value (I checked value from SMC_Interpolator - dVel ). In GCode G01, F value is F500, but movement is very slow, actual speed (dVel) is between 0 to 30 back and forth. I think very old CNC can move like that, but nowadays, a lot of CNC can move smoothly to process free curve ( somethimes option switch ) I tried to use G51 Dxx but I got the same result. My questions are 1) How do I improve CODESYS CNC motion in this case ? 2) How can I graph the sampling from dVel of SMC_Interpolate in CODESYS?
