Post by paulg on RasPi CAA Serial example - unexpected behavior during debug ^{CODESYS Forge talk (Post)}
I've trimmed down the CAA Serial Codesys example to only listen on one port but, when stepping through the Case structure in debug mode, it jumps out of the structure during a specific point in every scan (I'll point it out below after describing the setup and listing the code). I'm using a Pi 4 Model B, and I have an Arduino Nano Every plugged in via USB which is streaming the following serial message at 1 Hz: Time since opening connection: 1 s Time since opening connection: 2 s ...and so on. The Pi shows the Nano at /dev/ttyACM0 so I edited CODESYSControl_User.cfg to read: Linux.Devicefile=/dev/ttyACM The code in my PLC_PRG is (ignore some of the comments, I hadn't deleted them out from the original example): PROGRAM PLC_PRG VAR xStartTest : BOOL:= TRUE; iState : INT; xTestDone : BOOL;(* True, when the test was done succesfully *) (* Settings to communicate with the COM Port *) aCom1Params : ARRAY [1..7] OF COM.PARAMETER; como1 : COM.Open; comc1 : COM.Close; comw1 : COM.Write; comr1 : COM.Read; //sWrite : STRING := 'Test String!'; sRead : STRING(25); szRead : CAA.SIZE; xCom1OpenError : BOOL; xCom1CloseError : BOOL; xCom1WriteError : BOOL; xCom1ReadError : BOOL; END_VAR //This example shows the communication of two COM Ports with each other. //The first one writes a string of characters, which is read by the second one. //After successful execution, the two COM Ports are closed and the test is done. IF xStartTest THEN CASE iState OF 0: //The parameters are set for the COM Port aCom1Params[1].udiParameterId := COM.CAA_Parameter_Constants.udiPort; aCom1Params[1].udiValue := 1; // the correct Port should be adapted aCom1Params[2].udiParameterId := COM.CAA_Parameter_Constants.udiBaudrate; aCom1Params[2].udiValue := 115200; aCom1Params[3].udiParameterId := COM.CAA_Parameter_Constants.udiParity; aCom1Params[3].udiValue := INT_TO_UDINT(COM.PARITY.NONE); aCom1Params[4].udiParameterId := COM.CAA_Parameter_Constants.udiStopBits; aCom1Params[4].udiValue := INT_TO_UDINT(COM.STOPBIT.ONESTOPBIT); aCom1Params[5].udiParameterId := COM.CAA_Parameter_Constants.udiTimeout; aCom1Params[5].udiValue := 0; aCom1Params[6].udiParameterId := COM.CAA_Parameter_Constants.udiByteSize; aCom1Params[6].udiValue := 8; aCom1Params[7].udiParameterId := COM.CAA_Parameter_Constants.udiBinary; aCom1Params[7].udiValue := 0; //The first Port is opened with the given parameters como1(xExecute := TRUE, usiListLength:=SIZEOF(aCom1Params)/SIZEOF(COM.PARAMETER),pParameterList:= ADR(aCom1Params)); IF como1.xError THEN xCom1OpenError := TRUE; iState := 1000; END_IF //After a successful opening, the next state is reached IF como1.xDone THEN iState := 15; END_IF 15: // the reading process is started comr1(xExecute := TRUE,hCom:= como1.hCom, pBuffer:= ADR(sRead), szBuffer:= SIZEOF(sRead)); IF comr1.xError THEN xCom1ReadError := TRUE; END_IF //After completion the size of the written bytes are saved IF comr1.xDone OR comr1.xError THEN szRead := comr1.szSize; iState := 20; END_IF 20: // If everything was successful the ports are closed and the handles are released comc1(xExecute := TRUE,hCom:= como1.hCom); IF comc1.xError THEN xCom1CloseError := TRUE; END_IF IF comc1.xDone OR comc1.xError THEN iState := 25; END_IF 25: // The first port is closed and the used handle released xTestDone := TRUE; xStartTest := FALSE; iState := 0; como1(xExecute := FALSE); comw1(xExecute := FALSE); comc1(xExecute := FALSE); ELSE iState := 0; END_CASE END_IF I realize as I write this that the .udiPort should be 0 and not 1, but that shouldn't be causing the issue I'm seeing. I'm forcing xStartTest:=TRUE every scan so that I can step into each line and observe what's happening. What I see is that the port parameters are set and the port is opened with no errors, but the code jumps out of the case structure to the last line every time it reaches (and I step into) the iState:=15 line (at the end of the iState:=0 block). So every scan cycle it goes through the block for iState=0 and jumps out at the same spot. I'm a little new to PLC programming so I may be misunderstanding the flow, but shouldn't this case structure keep moving down in the same scan? If it only handles one case per scan, why doesn't the value of iState persist? Thanks! Update: I restarted the Codesys control today and I was then able to see an error for como1.eError of "WRONG_PARAMETER". I tried doing some digging and another post made me think I should add another line to CODESYSControl_User.cfg, so I now have: [SysCom] Linux.Devicefile=/dev/ttyACM portnum := COM.SysCom.SYS_COMPORT1 So now when I set .udiPort to 1, I get "NO_ERROR" but I also don't read anything from the port (i.e. szRead = 0 always). If I try setting the port to 0 (which I'm confused about, because I added a COMPORT1 line but the device shows on the Pi as ACM0), I get the "WRONG_PARAMETER" error again. Is there an easier way to troubleshoot the Pi and view what ports the Codesys runtime is actually able to see while the Pi is running?

Hi dgrard, I had the same issue for a long time, but on a WAGO webvisu. Now I'm glad that I can share my solution. I don't know if you are trying to use the webvisu or the target visu, but this works on webvisu: Get "go2rtc" and set it up according to the documentation. I'm running the Windows binary. Here's my example of the go2rtc.yaml config file (contains working example streams): api: listen: ":1984" # default ":1984", HTTP API port ("" - disabled) origin: "*" # default "", allow CORS requests (only * supported) static_dir: "www" # default "", folder for static files (custom web interface) tls_listen: ":443" # default "", enable HTTPS server tls_cert: "./SSL/fullchain.pem" tls_key: "./SSL/privatekey.pem" streams: # Streams with multiple links will fall back on the next link.

Post by alexgooi on OPC-UA and other communication questions ^{CODESYS Forge talk (Post)}
Dear forum, I currently have a big question mark above my head, and maybe this forum can shine some light on the situation. I recently updated to Codesys 3.15 SP19 Patch 6. And now I’m trying to setup the OPC-UA server, besides that I’m trying to connect to the controller with the Codesys V3 (Ethernet) protocol. OPC-UA I have installed the correct licenses on my controller (Runtime and communication). I’m able to connect to the controller with an OPC-UA client, and I’m able to browse the tags, so far so good. Therefore I’m assuming that the OPC-UA server is running on the controller. But now the strange part, in the device security settings I have set the communication Policy to BASCI256SHA256 ( I also have tried the other ones) and the communication mode is set to secure if possible (I also have tried all the other ones) (see picture). With these settings I would assume that I would only be able to login with a Basic256SHA256 policy with a client. But the opposite is true, I am able to login using the no policy mode and when I set it to Basic256SHA256 the client (UA-Expert) notes that this policy is not available on the server. I then check the certificates and I noted that there is no certificate for the OPC-UA server, I tried to generate one but it gave the error that the certificate has not been created by the device (See picture). To summarize I have no clue what is going on, and the controller does the opposite of what I would expect. Codesys Ethernet V3 driver I have a HMI connected to the same controller using the Ethernet V3 driver. But this will not connect. I tried all the Protocols (see picture), with and without the username and password enabled. But it will not connect, when I scan the available servers I can see the controller with the port number that I am expecting, so I’m assuming that the Codesys V3 ethernet driver is up on the controller. Does anyone can give me some direction, because the stuff that I tried doesn’t make sense to me. Thank you in advance

Post by greenwood on CODESYS Control Raspberry Pi mit Servotreiber T6 von StepperOnline ^{CODESYS Forge talk (Post)}
Hallo, ich versuche, eine Modbus-RTU-Kommunikation zwischen meinem Raspberry Pi mit CODESYS Control für Raspberry Pi 64 SL und einem Servotreiber von StepperOnline, Typ T6, herzustellen. Die Verbindung ist wie folgt: RJ45-Stecker am Servotreiber -> Kabel mit RJ45 an einem Ende und USB-A-Stecker am anderen Ende -> Seriell-zu-USB-Konverter -> Raspberry Pi. Der Seriell-zu-USB-Konverter und die Kabel habe ich zusammen mit dem Motor und Treiber von StepperOnline gekauft und sie sind dafür gedacht, den Servotreiber mit einem Computer zu verbinden, auf dem deren Setup-Software läuft. dmesg | grep tty auf dem Pi sagt mir, dass der USB-zu-Seriell-Konverter auf ttyusb0 ist. Ich weiß nicht, wie man das in einen COM-Port übersetzt, ich habe COM 1 genommen. Ich habe ein Projekt in Codesys erstellt und ein Modbus_COM-Gerät hinzugefügt, einen Modbus_Master_COM_Port und einen Modbus_Slave_COM_Port angehängt. Auf der Registerkarte "Allgemein" des Modbus_COM habe ich die folgenden Werte eingestellt: Slave address 1 Baud rate 9600 Parity None Data bits 8 Stop bits 2 Ich habe den Servotreiber auf die gleichen Werte eingestellt. (Ich habe auch andere Werte getestet, aber mit dem gleichen Ergebnis). Auf der Registerkarte "Modbus Slave Channel" des Modbus_Slave_COM_Port habe ich einen Kanal hinzugefügt und die folgenden Werte eingetragen: Access type Read Holding Registers (Function Code 3) Read Register offset 0x0000 Length 1 Ich habe noch keinen Code geschrieben, weil ich noch nicht herausgefunden habe, wie man die Kommunikation programmiert. Wenn ich das Projekt zum Raspberry Pi herunterlade scheint der Modbus_Master_COM_Port zu laufen (grünes Symbol), aber der Modbus_Slave_COM_Port nicht (rotes Dreiecksymbol). Wenn ich einen anderen COM-Port eintrage, haben sowohl der Master als auch der Slave das rote Dreiecksymbol. Ich habe dies auch mit meinem Windows-PC unter Verwendung von Codesys Control Win 64 versucht und die gleichen Ergebnisse bekommen. Ich wäre dankbar für jede Hilfe oder Tipps, wie ich den Grund dafür herausfinden kann, warum der Servotreiberreiber nicht reagiert.

Post by thommy54 on Lizenz wiederherstellen SP20 ^{CODESYS Forge talk (Post)}
Hallo Edwin, ich bräuchte mal eine schnelle Hilfe. ich testete einen zweiten Raspberry Pi 4 mit meinem Lizenzdongle eines laufenden Raspberry. Der 2. Raspberry ist als Redundanzlösung bei einem Crash gedacht. DIe Schwierigkeiten begannen, als ich mit dem Raspberry 4 V1.5 nicht mehr mit SP16 weiterarbeiten konnte. Ich updatede auf SP20.1. und die Schwerstarbeit begann. Das Image wurde rübergeschoben und alles auf dem zweiten Rechner soweit zum Laufen gebracht. Der Dongle wurde ebenfalls am 2. Rechner eingesteckt. Ob er überhaupt wirkte, kann ich nicht sagen, da für diesen Testfall Codesys so oft rauf und runter gefahren wurde, das die 2h-Grenze kaum erreicht wurde. Problem: Beim Zurückstecken des Dongles in den ursprücnglichen Rechner ist alles an Lizenzen weg. Der Lizenzmanager hat keinen Container mehr und der Befehl "lsusb" bringt nichts zurück. ich war der Meinung, das der Dongle genau für diesen Zweck gedacht war - die Lizenz von einem Rechner zum anderen mitzunehmen. Liege ich da falsch ? Wie komme ich nun wieder zu einem funktionfähigen Dongle ?? Weitere Versuche unternahm ich mit dem Wiederherstellen des Dongels. Dabei steckte ich ihn in meinen PC (Workstation) und siehe da, es werden noch 3 von ehemals (2020) 6 Lizenzzeilen angezeigt: (siehe Bild Problem_Lizenzen_Raspberry.jpg) Dann versuchte ich das Wiederherstellen über eine Lizenzaktualisierungsdatei vom Lizenzserver. Da kommt aber eine Datei mit anderem Dateityp (..WibuCmRaC) als im Lizenzmanager gesucht (WibuCmRaU). Die Datei ist dem Lizenzmanager auch nicht genehm (Bild Problem_Lizenzen_Raspberry_2.jpg). Nun steht Codesys auf besagtem Raspberry alle 2h still. Das soll die Lizenz doch verhindern. Angeblich soll seit SP13 auch kein eigenes Backup mehr nötig sein. Bis zum Erhalt des nicht brauchbaren Linzenzfiles hat da sja geklappt. Ich kann auch im Lizenzmanager keinen Punkt "Lizenz wiederherstellen" finden. Hat sich da mit SP20 etwas geändert? Wenn ich mir eine neue Lizenz hole - wie bringe ich sie auf den Dongle (der ja jetzt nicht "nagelneu" ist). Ich fürchte, das geht auch bloß schief. Im Voraus vielen Dank Thomas

Post by adamrobotic on llcallback() iec exception caught cmpid=0x00000002, eventid=0x00010008 ^{CODESYS Forge talk (Post)}
Hi All, Recently I have been experiencing a issue in CodeSys SP16 Patch 3, with a exception which comes up after I have made several online changes. callcallback() iec exception caught cmpid=0x00000002, eventid=0x00010008, after I experience this fault then I receive a error message for any subsequent online change "online change failed, no task gap within 10000ms". To recover either the controller needs a orgin reset, which will allow online edits thereafter until falling back into the loop. I am using a TURCK TX707 product which is controlling robot trajectory, We have hard coded the coordinate data rather than using persistence variables so hence the need to do online changes consistently. I have read on the forum other people have experienced similar issue with the online task gap, but I have no task which have same priority and also monitored the CPU usage and have not seen it go above 13%. Anyones help would be much appreciated, thankyou.

Post by cdutz on Problems connecting to Codesys 4.9.0.0 runtime on my Wago PFC200 ^{CODESYS Forge talk (Post)}
Turns out I managed to get a connection to my PLC. It seems that a few weeks ago Wago released something with version 4.3.3(25). So I reset my PLC to Factory-Reset, set it to the 192.168.1.17 IP and changed the IP to the one I wanted with the Wago EthernetSettings tool. Then updated the latest firmware using the WAGOupload tool. Now the PLC came back up without a PLC runtime running, so in the Web-tool I wen't to the "Configuration"/"PLC Runtime" and selected the runtime version "CODESYS V3". I uninstalled all Codesys versions and installed the version from the download package of Wago together with all the packages the bundle provided. After creating a new project I didn't select the old PFC200 runtime, but one of the dozens of new device profiles, that it now listed. With these settings I was then able to connect to my PLC. Now I hope I'll get the existing project that I had ported to this new structure. Sorry for the noise. Chris

Post by egret on Issue with J1939, PGN 65267 (Vehicle Position) ^{CODESYS Forge talk (Post)}
I have a J1939 network (ISOBUS) connected to my PLC. I can receive various PGNs such as 65256 (Vehicle Direction/Speed) and 65254 (Time/Date). However, I cannot receive 65267 (Vehicle Position). PGN 65267 (VP) contains SPN 584 (Latitude) and SPN 585 (Longitude). On the network both SPNs return a value of -210 (meaning the CAN message payload is zero in both cases). The conversion settings are the default values and appear to be correct (see attached screenshot). Using a CAN analyser I can see that PGN 65267 (Vehicle Position) is being transmitted over the network with valid (non-zero) data that matches the latitude and longitude coordinates I would expect. I've created a program to read the raw J1939 data and this also returns valid data. It seems that the Codesys J1939 database has a problem with reading PGN 65267 messages. Can anybody else confirm this? I'm using Codesys Version 3.5 SP16 Patch 5.

Post by rcaponi on Codesys Control RTE V3. Remote Control ^{CODESYS Forge talk (Post)}
Hello, I would like to have, if possible, some clarification on this function. That is, I would like to understand if it is useful for managing, fom my development PC, the RTE runtime executed on a remote control. This is what the help says: Remote PLC: Opens the Remote Configuration dialog. By enabling or disabling the Control remote PC, not local option, you determine whether a PLC is used that is on a remote or local PC. Accordingly, the menu commands Start PLC, Stop PLC, and PLC Configuration refer to the local PC or a PC reached on the network. For the remote PC, specify the Target PC address, Port number, and a Timeout value (in ms) for the connection (Remote Timeout [ms]). But does this mean that I also need to install the RTE runtime on my development PC? Is it possible to have some more information? Best regards Roberto Caponi

Post by sturmghost on Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
Im looking for a way to implement ST-code into the visualization element without creating a helper POU or method in my device/application tree. Like visualization properties are evaluated at each VISU_TASK cycle I want to be able to create own ST code which interacts with the visualization interface variables. To be more specific I want to have a property which executes user defined ST-code at each VISU_TASK cycle exactly like its already possible for Input Configuration on various mouse and dialog events. Also a property for initialization (so only executed once) and a timed property would be nice. With the situation right now I'll have to create a POU function which handles the ST-code and misuse a property, like the text variable, to execute this POU function at each VISU_TASK cycle. Or does it exist and I don't know it?

Post by moksan on Unconnected_Send Explicit message with Route Path ^{CODESYS Forge talk (Post)}
I have been trying out Unconnected_Send Explicit Message with route path.(The Unconnected_Send service shall use the Connection Manager object in each router to forward the message and to remember the return path. Vol 1.3 / 3-5.6.7) However, I could not see the correct path on Wireshark. I want to see the Unconnected_Send Message Service Code as 0x52 and also the last of the message should have the route path. I want to ask some questions about this topic. The IIoDrvEIPAcylicServices Interface has the IoDrvSendUnconnectedMessage Method. And there is a struct (EIP_SendUnconnectedMessage) for this service. But there is no information about how to implement to project, and if it is successful, does it send a message with 0x52 Unconnected_Send Service Code or not? If that is not a solution, how can I set the Unconnected_Send Explicit Message struct on Codesys? Also how can I send explicit message with route path?

Post by mondinmr on Jitter problems on imx8 ^{CODESYS Forge talk (Post)}
We are experiencing serious jitter issues on an ARM64 imx8. Until now, on rpi and beaglebone derivatives, and on Intel, we never encountered jitter issues unless they were already present on the device. In this case, as can be seen from the attached graph, we have excellent maximum latency. The cyclictest on the isolated core dedicated to IEC CODESYS tasks shows a latency of 37µs, with an average of 14µs. Usually, on all other devices, with an RT kernel, with the appropriate parameters to avoid frequency throttling, with properly managed IRQs, and with the disabling of large page sizes, the jitter measured by CODESYS is very close to the cyclictest latency. However, on this imx8, we are noticing a fluctuating value of +/- 300µs that seems to be added to this latency, as if something occasionally miscalculates the sleep times by exactly +/- 300µs. Two screenshoot attached. - Result of cyclictest - Jitter on CODESYS Tasks are assigned to isolated core!

Post by vassilis91 on EtherCat-Rexroth Drive lost connection or no? ^{CODESYS Forge talk (Post)}
Hi all, i am encounter a mystery problem with a build with rexroth drives at my work. At my company we are make a machine with two Rexroth Indradrives . The two drives are goes by ethercat protocol . To be more specific i am going from my plc to the Beckoff El1100 coupler and after to the first drive and from the first drive to the second. The second drive works with no problem but the first(motor) sometimes without any pattern start to make a mysterious noise like stop and suddenly goes on again. If i couldn't hear the noise from the motor i couldn't Imagine that this happen. After a lot of research i see that sometime i have some strange zeros from the drive to the plc? Really i am in a deadlock and I don't know how to continue. From the other side the values on the other drive(second)are stable . The problem maybe: https://youtube.com/shorts/g7PCFLUaDUI?si=eiq0F2IzhQZax2e2

Do you need an 'hours-run' counter? And 1 second resolution is ok? I think you're over-thinking it. (The task time needs to be < 1second) Have a look at the LAD... Then, the time in seconds can be made into hh:mm:ss with this FUNction Declarations: FUNCTION funSecondsToStringTime: string VAR_INPUT InSeconds: UDINT; END_VAR VAR AsString: STRING; Minutes: UDINT; Hours: UDINT; Seconds: UDINT; MinutesAsString: STRING(2); HoursAsString: STRING(2); SecondsAsString: STRING(2); END_VAR and the code: Hours := InSeconds / 60 / 60; //Derive hours Minutes := (InSeconds - (Hours * 60 * 60)) / 60; //Derive minutes Seconds := InSeconds - ((Hours * 60 * 60) + (Minutes * 60));//Derive seconds HoursAsString := UDINT_TO_STRING(Hours); MinutesAsString := UDINT_TO_STRING(Minutes); SecondsAsString := UDINT_TO_STRING(Seconds); IF LEN(HoursAsString) = 1 THEN HoursAsString := CONCAT('0',HoursAsString); END_IF; IF LEN(MinutesAsString) = 1 THEN MinutesAsString := CONCAT('0',MinutesAsString); END_IF; IF LEN(SecondsAsString) = 1 THEN SecondsAsString := CONCAT('0',SecondsAsString); END_IF; AsString := CONCAT(HoursAsString, ':'); //assemble string AsString := CONCAT(AsString,MinutesAsString); AsString := CONCAT(AsString,':'); AsString := CONCAT(AsString, SecondsAsString); funSecondsToStringTime := AsString;

Post by andrax on Meine Gerätesammlung basierend auf TCA9548 ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich programmiere öfters mal kleinere Messgeräte und Datenlogger. Je nach Einsatzzweck musste ich mir ein paar Gerätetreiber selber schreiben. Da es eine recht große Sammlung ist, stelle ich die hier einfach mal ein. Die Sammlung basiert auf den Gerätetreiber TCA9548 Multiplexer von Steffen Dreyer. Codesysversion: V3.5 SP18 Patch 4 Inhalt: -4channel Dimmer (Stefan Dreyer) -BMA456 (Andre Klien) -BME280 (Stefan Dreyer) -BMP280 (Stefan Dreyer) -EEPROM_24C512 (Stefan Dreyer) -ADS1115 (Andre Klien) -ICP10125 (Andre Klien) -PCA9555 (Stefan Dreyer) -PCA9685 (Stefan Dreyer) -PCF8575 (Stefan Dreyer) -SDP810 (Andre klien) -SSD1306 (Stefan Dreyer) -TCA9548 (Stefan Dreyer) -TSL2561 (Stefan Dreyer) Alle Gerätetreiber laufen über den Multiplexer, können aber auch ohne betrieben werden. Einschränkung: BMA456: Die Konfigurationsdaten werden erfolgreich in den Chip geschrieben, dieser meldet aber config wrong. Warum auch immer, der Sensor funktioniert und bringt hochempfindlich Beschleunigungsdaten. ADS1115: Hie habe ich nur die wichtigsten funktionen implementiert. 1-4 Kanäle, PGA, kontinuierlicher Modus, Datenrate. Alle anderen Funktionen (single-shot, komparator,alm) sind nicht implementiert. Das macht auch keinen Sinn, da diese Funktionen besser über die Steuerung realisiert werden können. Achtung beim ADS1115 ist zwingend ein Levelshifter notwendig, wenn ihr diesen mit 5V betreiben wollt. Ihr grillt sonst euren Raspi (SDA, SCL sind dann 5V) Gruß Andre

Post by dhumphries on Minimum system requirements for codesys control standard S ^{CODESYS Forge talk (Post)}
I'm working on a low cost project and I'm considering installing the Codesys runtime on a PC running Linux Debian instead of buying a PLC with a pre-installed runtime. For my needs the Control Standard S license should be capable of running some IO over ethernet/ip, and a webvisu. The PC I am considering has a AMD GX-424CC 2.4GHz processor (4 core/4 thread) and 4GB RAM. This may compare to a raspberry pi4, but I know an X86 processor doesn't directly compare to an ARM processor, and a processor can have a high clock speed but other factors like L2/L3 cache can influence the overall performance. I can't find any published specs for the processor and RAM requirements to run the Codesys Control runtime, does anybody have a link to the minimum system requirements or experience using devices that are at or below the minimum system requirements. A raspberry pi with the control for raspberry pi SL runtime license would be the lowest cost option, but the license is not for commerical use. This restriction is somewhat vague, can anybody clarify if this means I can use a raspberry Pi runtime for in-house automation, what about if I am selling an integrated system that uses a raspberry Pi as a controller?

I found the J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup function blocks and they seem like a good solution for my problem, I just can't get them to work from my understanding you just build the J1939.ReceiveParameterGroup once and then connect it's output to the J1939.ReceiveWatchdog, here's my CODE for the setup HEARTBEAT_TIMER(IN:= TRUE, PT:= T#1000MS); //turn-on delay because of initialization race IF HEARTBEAT_TIMER.Q= TRUE THEN Glob_Var.DisplayReceive.xExecute:= TRUE; Glob_Var.DisplayReceive.itfECU:= Valve_X; Glob_Var.DisplayReceive.dwPGN:= 65511; Glob_Var.DisplayWatchdog.xEnable:= TRUE; Glob_Var.DisplayWatchdog.itfParameterGroup:= Glob_Var.DisplayReceive.itfParameterGroup; Glob_Var.DisplayWatchdog.tTimeout:= T#1500MS; END_IF Notes: Glob_Var.DisplayReceive is of type J1939.ReceiveParameterGroup Glob_Var.DisplayWatchdog is of type J1939.ReceiveWatchdog The above code is done once and not cyclically I'm monitoring Glob_Var.DisplayWatchdog.xError cyclically

Post by alexgooi on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi Duvan, You could make this in 1 single object (FB), Indeed don't use a function for this beacuse you need some memory to keep the old value. For i := 0 TO 200 BY 1 DO //Check if the value has been changed IF Old_Value[i] <> Value[i] THEN //Set the trigger to TRUE Trigger[i] := TRUE; Old_Value[i] := Value[i]; END_IF END_FOR If you define the Value array as an In_Out and the Trigger as an In_Out you arn't claiming any aditional memory to your system. You ofcourse then need to add some code arround it that does something with the trigger and writes it back to FALSE again. If you want more flexability you also could use pointers instead of using the IN_OUT FOR i := 0 TO 200 BY 1 DO address := address_Input + i * SIZEOF(*Put type here); IF Address^ <> Old_Value[i] THEN Trigger[i] := TRUE; Old_Value[i] := Address^; END_IF END_FOR
