Post by testlogic on Sending Sequential Modbus TCP Packets ^{CODESYS Forge talk (Post)}
I have a Modbus TCP slave device where I need to do sequential writes to the same register. The register I'm writing to is kind of like a command line, each packet is a command word encoded in Hexadecimal. I am having difficulty implementing this system in CoDeSys 3.5 SP19. I feel like the structure of the program should be something along the lines of (Pseudocode): ModbusTCPSend(Command Register, Command1) ModbusTCPSend(Command Register, Command2) ModbusTCPSend(Command Register, Command3) I have tried to implement this with a rising edge trigger wMot1OPCode := 16#E1; //Stop Motor & Kill Program xMot1SendOP := TRUE; //Send OP on rising edge xMot1SendOP := FALSE; //Reset wMot1OPCode := 16#9E; //Disable Motor xMot1SendOP :=TRUE; //Send OP on rising edge xMot1SendOP := FALSE; //Reset Where "wMot1OPCode" is the IO map for writing to the command register, and "xMot1SendOP" is the rising edge trigger for that modbus channel. However, this doesn't work. The device never responds to the modbus commands. It seems like the trigger variable is switched too quickly for modbus to send the packet. I know the modbus register is working, because I can set the channel to cyclic and the device will respond. However, I can't use this reliably because I need each command to be sent once, in order. Cyclic keeps re-sending the commands and seems like it could miss a command as well if one was sent in-between cycle time. I have also trying using the Application trigger as described by https://faq.codesys.com/pages/viewpage.action?pageId=24510480, but this is also not working for me. See attached picture for my FBD code. This seems like a simple function, I can't tell what I'm doing wrong here. Thanks for the help.

Post by iliyatsukerman on SoftMotion auf PFC200 ^{CODESYS Forge talk (Post)}
Hallo, Wir würden Ihre Unterstützung bei der Überprüfung der Kompatibilität der folgenden Konfiguration sehr schätzen: • PSTR-LO-16/400FEV ELMO • SCALANCE XC208 • WAGO PFC200 750-8213/40-010 • Die SPS (WAGO) wird gleichzeitig eingesetzt als: o EtherCAT-Master zur Kommunikation mit einem Elmo-Servoantrieb (EtherCAT-Slave, 4 Achsen – generisches CiA 402-Profil), und o Modbus-TCP-Server zur Kommunikation mit einem Siemens Modbus-TCP-Client, welcher zur Fernsteuerung des Elmo-Servoantriebs über die SPS dient. Bitte bestätigen Sie, ob die SPS in der Lage ist, diese Dualfunktion — als EtherCAT-Master und gleichzeitig als Modbus-TCP-Server — ohne Konflikte oder Performanceprobleme zu unterstützen. Insbesondere interessiert uns, ob die CODESYS SoftMotion SL Basislizenz (2305000000-F) notwendig ist, um 4 Servoachsen zu steuern, und ob diese Lizenz auf einer WAGO PFC200 SPS mit CODESYS Version 3.5 Service Pack 19 Patch 40 oder höher unterstützt wird. Alle Achsen im Servoantrieb werden unabhängig voneinander gesteuert. Mit freundlichen Grüßen. ILIYA

Post by francescoc on Custom log CmpLog ^{CODESYS Forge talk (Post)}
Hi, I am trying to create a log in my application. Since I cannot find any documentation regarding modifying the codesys configuration file to be able to log in ms, i tried to create a new log via CmpLog.LogCreate. Below is the part of the code where I create the logger and write a test string. In the log tab of codesys I actually see the new log that was created, but it is empty, and in the folder I cannot find any files. I can't find any detailed documentation. Can you guys give me support? Are there any examples? Thank you IF NOT FirstCycle THEN LogName:= 'LOGS/TestLog'; LogOptions.bEnable:= 1; LogOptions.iMaxEntries:= 5000; LogOptions.iMaxFiles:= 100; LogOptions.iMaxFileSize:= 5000; LogOptions.szName:= LogName; LogOptions.uiType:= CmpLog.LogTypes.LT_TIMESTAMP_RTC_HIGHRES; LogOptions.uiFilter:= CmpLog.LogClass.LOG_ALL; LogHandle:= CmpLog.LogCreate(pOptions := ADR(LogOptions), pResult:= ADR(Result)); LogHandle:= CmpLog.LogOpen(pszName:= LogName, pResult:= Result); Component_Manager.CMAddComponent2('TestLogNEW', 16#00000001, ADR(udiCmpIdNEW), 0); CmpLog.LogAdd2(LogHandle, udiCmpIdNEW, CmpLog.LogClass.LOG_INFO, 1, 1, 'Logger started...'); END_IF IF TestWrite THEN TestWrite:= FALSE; CmpLog.LogAdd2(LogHandle, udiCmpIdNEW, CmpLog.LogClass.LOG_INFO, 1, 1, 'Write test'); END_IF

Post by paro on Modbus Client Request Not Processed ^{CODESYS Forge talk (Post)}
Hi, Problem in your code is that you are not calling the ClientFb cyclic. Please look at the Example from CODESYS: https://forge.codesys.com/prj/codesys-example/modbus/home/Home/ Your code works if the client fb is called cyclic! IF NOT initDone THEN initDone := TRUE; // configure clientTcp clientTcp(aIPaddr:=Ethernet.IPAddress, uiPort:=502); // configure clientSerial clientSerial(iPort:=SysCom.SYS_COMPORT2, dwBaudRate:=SysCom.SYS_BR_115200, byDataBits:=8, eParity:=SysCom.SYS_EVENPARITY, eStopBits:=SysCom.SYS_ONESTOPBIT, eRtuAscii:=ModbusFB.RtuAscii.RTU); // configure clientRequestReadCoils_1 clientRequestReadCoils_1(rClient:=clientTcp, uiUnitId:=42, udiTimeout:=TO_UDINT(T#10MS)); // configure clientRequestWriteSingleRegister clientRequestWriteSingleRegister(rClient:=clientTcp, uiUnitId:=43, udiTimeout:=TO_UDINT(T#10MS)); // configure clientRequestReadCoils_2 clientRequestReadCoils_2(rClient:=clientTcp, uiUnitId:=44, udiTimeout:=TO_UDINT(T#10MS)); // configure clientRequestReadInputRegisters clientRequestReadInputRegisters(rClient:=clientTcp, uiUnitId:=44, udiTimeout:=TO_UDINT(T#10MS)); END_IF // call the client FB's clientTcp(); clientSerial(); // call client request FB's clientRequestReadCoils_1(rClient:=clientTcp, xExecute:=TRUE, uiStartItem:=2, uiQuantity:=3, pData:=ADR(aDataCoils_1[0])); // for more details see Example_TCP, especially ClientRequest control (xExecute, xDone, xError). IF clientRequestReadCoils_1.xDone THEN // get data from aDataCoils_1 ... END_IF clientRequestWriteSingleRegister(rClient:=clientTcp, xExecute:=TRUE, uiItem:=3, uiValue:=123); clientRequestReadCoils_2(rClient:=clientTcp, xExecute:=TRUE, uiStartItem:=2, uiQuantity:=3, pData:=ADR(aDataCoils_2[0])); clientRequestReadInputRegisters(rClient:=clientTcp, xExecute:=TRUE, uiStartItem:=16, uiQuantity:=3, pData:=ADR(aDataInputRegisters[0]));
