I'm having trouble getting started with the SysFile library. I tried copying and running the code found here: https://forge.codesys.com/forge/talk/Engineering/thread/f17c3d0e64/ Every time I try to run the file handle pointer returns: 16#FFFFFFFFFFFFFFFF <dereference of="" invalid="" pointer=""></dereference> I can see the file when I look in the Device -> Files window Any idea what I'm doing wrong?

Hi if you add in (ttyAMA0 should fit to your HAT's device [SysCom] Linux.Devicefile.1=/dev/ttyAMA0 to /etc/CODESYSControl_Usr.cfg since 4.12.0.0 version /etc/codesyscontrol/CODESYSControl_Usr.cfg then access in CODESYS with Com1 should do it. Keep in mind that only adapters work (for RS485) which do determine the send/receive direction in hardware

yes i took the library from another forum: https://forge.codesys.com/forge/talk/Runtime/thread/f1400b71b6/, it is made for the ads1115 but the ads1015 is almost the same device with same adresses i only changed the divide value of the analog value, because thats the only difference between the ads1115 and ads1015.

Okay i will try. I tried already the different settings. The CodeSys version i use, is CodeSys 3.5 SP20 Patch 3. The device which i use is CodeSys Control For Raspberry PI 64 SL version 4.13.0.0. The wiring should be okay because i'm using the Edatec ED-CM4IND-1432-4C(EU).

I don't have a multiplexer so it very weird that it connects with that multiplexer. If i do a I2C scan on the PI terminal, i only get the device addresses 0x48 and 0x51. One for the ADC and one for RTC. I will try again with your libraries

Post by giackanto on Eoe issues with Windows and Linux ^{CODESYS Forge talk (Post)}
Hello, I've been trying to use EoE for communication between a Windows PC and an M753 drive from Control Technique. Despite following some online guides (https://content.helpme-codesys.com/en/libs/EtherCATStack/4.3.0.0/Ethernet_over_EtherCAT/fld-Ethernet_over_EtherCAT.html) I haven’t had any success. Both are connected to a Debian device where RTE is running: The PC is connected via the Ethernet port. The drive is connected via the EtherCAT port. I'm unable to ping the drive from my Windows PC. Here is my configuration: On Debian: (See attachments 1, 2, 3) enp1s0 = Ethernet port enp2s0 = EtherCAT port tap2 = TAP device IP forwarding and routes are both configured. On Windows: (See attachments 4, 5) On Codesys: (See attachments 6, 7) Version: Windows 11 Debian GNU/Linux 11 Codesys 3.5.17 Control for Linux SL 4.7.0 EtherCAT 4.4.0 With this configuration, I can ping the TAP device, but not the drive (See attachment 8). Could someone explain how to properly configure all these settings? Thank you, GA

Post by tim-roelant on Profinet fault with codesys control V3 - Receive packet error ^{CODESYS Forge talk (Post)}
I have set up a brandnew Beckhoff panel pc with a codesys control runtime V3. I configured it together with 2 profinet field devices: a 16in/16out IO module from Turck and an MTS linear encoder. The machine works fine untill all of a sudden the communication breaks and the profinet participants become unreachable. At that point I can still ping the device, but the profinet master does not find them anymore: When i do a scan they are not found. When i do a cold restart, the profinet master becomes active again and the devices are found again. In the log i get Ethercat packet receive error: sysethernet. I am a little confused, there is no ethercat device in the device tree. I already set the send clock and the reduction ratio to higher values, but without result. Can codesys be configured, so that the communication re-establishes without doing the cold reset? This is very annoying and is causing a lot of prodution losses. regards Tim

Post by mikek10 on Ethernet/IP 4.6.0 causing exceptions? ^{CODESYS Forge talk (Post)}
Hi, I have a project currently in development, it has a number of Ethernet/IP devices (18 adapter devices with Codesys as scanner, another scanner device with codesys as adapter). This has been stable whilst on factory floor for several months (though prior to that I did have some Ethernet/IP issues which were resolved by adjusting RPI rates). Today I tried updating to Ethernet /IP 4.6.0 from 4.5.1, subsequent to this I had 2 exceptions in a 2 hour period, I reverted to 4.5.1 and have had no further exceptions. Note I do have a device (Zebra printer) that frequently times out and reconnects, this does not seem to cause any issues in operation and does not cause any exceptions with 4.5.1. I believe the root cause of this is on the Zebra side, however there does not seem to be any adjustment I can make to prevent the time outs. Information from device log is in screenshot attached.

Post by mondinmr on First IO address of a CAADiagDeviceDefault. ^{CODESYS Forge talk (Post)}
I have a device CAADiagDeviceDefault: IoConfig_Globals.Axis_A In our library, we perform introspection of the Etc_SlaveDiag. In that case, we have connectors, and by searching for them by address, I can find them in the IO mapping using the offset and size provided by EtherCAT. However, a Lenze i700 drive, instead of placing the IO mapping in the Etc_SlaveDiag device, places it in a sub-device CAADiagDeviceDefault. So, when I perform introspection, I cannot find the IO correspondences. Yet, in the CAADiagDeviceDefault, I do not find the connectors and cannot do the matching. Is there a way with a pointer or reference to a CAADiagDeviceDefault to obtain the address of the first input and the address of the first output? This is because we have our own motion library with many EtherCAT devices that automatically configure the mappings, but I can't manage to do so with the Lenze i700.

Post by lbartik on J1939 TX/RX PDU1 ^{CODESYS Forge talk (Post)}
Is it possible to transmit a PDU1 PGN using the J1939 manager and local device? What if I need to transmit a PGN RQST via 0xEA00 (PGN 59904)? How would I do this P2P (Destination < 0xFF) or broadcast (Destination 0xFF)? I don't think this is possible for any destination type. I don't think it's possible to receive broadcast PDU1 messages either. For example, an address claim PGN 60928 (0x18EEFF80) is addressed to all nodes (0xFF) and not any specific local device so it will be filtered out. These are major oversights in the IoDrvJ1939 library to not support every PDU1 RX/TX scenario. IoDrvJ1939 supported scenario: 1. Receive (RX) PDU1 (P2P) destination-specific (PDU-specific < 255) to local device with matching address IoDrvJ1939 unsupported scenarios: 1. Receive (RX) PDU1 (P2P) global (PDU-specific = 255) 2. Transmit (TX) PDU1 (P2P) global (PDU-specific = 255) 3. Transmit (TX) PDU1 (P2P) destination-specific (PDU-specific < 255)

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Hello everyone, I have a very simple program for the process, but it's driving me crazy and I can't see the problems I'm left with: Short topological description: Dual Core Berghof controller with softmotion runtime version 3.5.19.30; Two axes with servodrive on canopen bus, clocked distributed from master; Ethercat I/O node; 2 ms ethercat task, 2 ms canopen bus cycle time; I/O objects of the canopen master and canopen drives connected to the ethercat task cycle; Problem 1: Two separate programs each manage their own axis and drive, with separate state machines. A first axis moves primarily in velocity, except having to position itself absolutely at a predetermined point at the end of the job; the second axis, on the other hand, is a paper unwinder that changes, for each job cycle, from actions in absolute, relative, and cam displacement with the master axis. Well, the state machine of both axes was written in such a way as to call running the useful FB and change it on state change in this way: CASE i_stateMachine OF 0: o_Power(Enable := TRUE, bRegulatorOn := FALSE, bDriveStart := FALSE, Axis := o_PaperUnwinderAxis); o_MoveAbs(Execute := FALSE, Axis := o_PaperUnwinderAxis); o_MoveRel(Execute := FALSE, Axis := o_PaperUnwinderAxis); o_CamSelect(Execute := FALSE, Master := o_MachineAxis, Slave := o_PaperUnwinderAxis, CamTable := cam_PaperUnwinder); o_CamIn(Execute := FALSE, Master := MachineEncoder, Slave := o_PaperUnwinderAxis); o_CamOut(Execute := FALSE, Slave := o_PaperUnwinderAxis); o_SetPosition(Execute := FALSE, Axis := o_PaperUnwinderAxis); IF ... THEN i_StateMachine := 10; END_IF; 10: o_Power( Enable := TRUE, bRegulatorOn := TRUE, bDriveStart := TRUE, Axis := o_PaperUnwinderAxis ); IF o_Power.Status THEN i_StateMachine := 20; END_IF; 20: (* Avanzamento carta *) o_MoveAbs( Execute := TRUE, Position := o_Somewhere, Velocity := 25.0, Acceleration := 3666.7, Deceleration := 3666.7, Jerk := 48000.0, Direction := MC_DIRECTION.positive, Axis := o_PaperUnwinderAxis ); IF o_MoveAbs.Done THEN o_MoveAbs(Execute := FALSE, Axis := o_PaperUnwinderAxis); i_StateMachine := 30; END_IF 30: d_HomingPosition := ...; o_SetPosition( Execute := TRUE, Position := d_HomingPosition, Mode := FALSE, Axis := o_PaperUnwinderAxis ); (* ... *) IF o_SetPosition.Done = TRUE THEN o_SetPosition(Execute := FALSE, Axis := o_PaperUnwinderAxis ); o_LogServer.Append(sMessage := '...', lscClass := LOGSERVER_CLASS.ALWAYS, sdt := o_CommonsMgrData.systime.sdtLocal); i_StateMachine := 40; END_IF; 50: ... The code above is a sketchy example of what I wanted to write. But it gives me a spot problem: in some, the state change results in a drive error, which is unrecoverable except with a reinitialization via SM3_ReinitDrive(). Things are improved a little if in the program I always run the call of all softmotion blocks in this way: o_Power(Axis := o_PaperUnwinderAxis); o_Jog(Axis := o_PaperUnwinderAxis); o_Halt(Axis := o_PaperUnwinderAxis); o_MoveAbs(Axis := o_PaperUnwinderAxis); o_MoveRel(Axis := o_PaperUnwinderAxis); o_CamIn(Master := MachineEncoder, Slave := o_PaperUnwinderAxis); o_CamOut(Slave := o_PaperUnwinderAxis); If I don't execute all the calls of all the motion FBs used, when exchanging machine state often (but not always), the axis goes into error with event id THE_FB_WASNT_CALL... Done a little diagnostics it seems that the FBs return the bDone, before they are completely terminated. I tried doing the machine state exchange not with the bDone bit of the FBs, but with the 'standstill' state of the axis. It didn't seem to change anything. Problem 2: During the use SM3_ReinitDrive() I get the erro in the log: "NetID 0: SDO read error for object 16#607C..." Assuming that the device involved it's one of the two servodrive, (no others device are present in the network), I don't found any object 0x607C in the 'possible object list in/out' of the two drive, and I don't understand where this object can be listed. So any ideas and suggestions regarding these two issues will be very, very welcome. If you need the source project, I am willing to send it.

Post by r-niedermayer on OPC UA subscriber not operational ^{CODESYS Forge talk (Post)}
Hi. As far as projects in "old version"s are concerned, these can be upgraded to newer versions at any time. To do this, the device must be updated accordingly and the copilers and library versions must be adapted. You can find instructions on how to proceed in the online help/FAQ: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_changing_compiler_version.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_cmd_update_device.html See also 4.3.22.4 "How to open an Example Project" within the following pdf for more details on the single steps: https://forge.codesys.com/lib/counit/tickets/_discuss/thread/3e991befbc/ca97/attachment/Public%20FAQ-v13-20240610_075228.pdf Regaring your OPCUA connection state always showing just "DISABLED", without knowing both sides of the assembly in detail, one can only approach the problem theoretically. We can give a chekclist on how to proceed: Fist, please recheck the communication settings in the OPC UA connection function block to ensure that the server URL, endpoint URL, and other settings are correct and match the configuration of the OPC UA server. Verify that the OPC UA server is running and accessible. -You can try to connect to the OPC UA server using a separate client, such as UAExpert, to ensure that the issue is not related to the OPC UA server itself. Test the security settings in the OPC UA connection function block to ensure that the correct security policy and certificate are selected. If you are using a dynamic connection to the OPC UA server, probe that the connection settings are correctly configured and that the OPC UA client is able to establish a connection to the OPC UA server. Also, please loock into the log files for any errors related to the OPC UA connection function block, these should be listet there. The log files may also provide additional information about the issue and help you to further troubleshoot the problem. FYI - Please see https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_obj_data_source_communication_opc_ua_server.html: Her you can finde the Communication settings via OPC UA Server -> layout Browse Live Server: The client connects to the server and detects the existing variables and types. From Information Model The client reads the data structure (layout) of the OPC UA Server from the information model set here and as a result receives the information about available variables and types. A connection to the server is not required. The list contains the information models installed in the OPC UA Information Model Repository. "Read Connection" Settings from IEC Variable (option set): - The connection settings used by the device are not read here from the dialog, but at runtime from the IEC variable specified here. - For this possibility, please see the Using a Dynamic Connection to an OPC UA Server (https://content.helpme-codesys.com/en/CODESYS%20Communication/_comm_use_dynamic_opc_ua_server_comm_settings.html) The settings for the communication of a Client-data source to an OPC UA Server can also be dynamically configured from the IEC code and can also be changed at runtime. For such a purpose, a structure is available in the DatasourceOpcUAServer library (For a description of the OPC UA Server, there is one included in the standard installation of CODESYS, https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_encrypt_communication_data_sources_opc_ua_client.html)

So far I did it with a Microcontroller and now I wanna upgrade my Projekt with Raspberry Pi and Codesys Software to be more flexible. I tried to adapt PiFace Function Block to just send or recive a 8 bit via SPI interface of the my Raspberry Pi. With following code (see attached screenshots) * PLC_PRG * PiFaceDigital * PiFaceDigital.write8 * PiFaceDigital.read8 I have a signal at SCK and MOSI pin of the PI, so far so good. But I really struggle with the unterstanding of the code. Is there some detailed description of each line of code? Or is there somebody in the community who can explain each line of code? Or is there a more simple way to send / recive 8 bit via SPI? Manuel

Some of the things I have tried; Username and passord; Credientials from the raspberry Administrator Administrator admin admin Admin Admin administrator administrator Usernames and passwords that I sometimes use (this was a longshot i know, but i was running out of ideas and energy). :) Epand filesystem, activating i2c, spi, 1-wire I can start the gateway and start the runtime. I cant install the edgearm64, arm64 runtime package eventhough I guess i should, i get code [ERROR] Error output: dpkg: error processing archive /tmp/codesysedge_edgearm64_4.8.0.0_arm64.deb (--install): [ERROR] Error output: package architecture (arm64) does not match system (armhf) [ERROR] Error output: Errors were encountered while processing: [ERROR] Error output: /tmp/codesysedge_edgearm64_4.8.0.0_arm64.deb code as a respons. I have tried to Reset Origin Device - no change. I have tried to remove the /etc/CODESYSControl_User.cfg [CmpUserMgr] but i could not find it and i was not sure if i should add it instead but i did not want to mess somthing up. I have tried to create a second gateway with the specific ip if the pi, that did not help. Could it be that i´m currently connected to the pi through WIFI? I can ping the pi and I can connect and control it through VNC. When i scan to select gateway target (scan edge gateway) i find 17-21 devices but can find the pi throug the mac adress. I started of trying to use the "CODESYS Control for Raspberry Pi SL" (I have a license sience earlier) as i read somewhere that this could be used on a Pi4 as well but now i´m trying with the MC SL, no changes, same problem. Right now - gateway version 4.8.0.0 (edgearmHF, armhf), Runtime Package 4.5.0.0 (raspberry, armhf). Any sugestions are very welcome! As mentioned above, theese are some of the things that i have tried/done - but i have been going at this for a while. Best, Martin

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.

Update: This initial issue was when using a Linux target PLC. Since then I have created a Win10 target PC and the Codesys software reported an issue associated with the device version (see attached). I am assuming this is an incompatibility with the xml file from the manufacturer and the firmware version on the module and I am chasing this up with Beckhoff. Question is, why would this not report with a Linux target?
