Post by latassan on RaspberryPi 5 gateway problem ^{CODESYS Forge talk (Post)}
Hello, I'm trying to use a raspberryPi 5 as a PLC. I fixed its IP address, I can ping it. I've also installed the CODESYS Control for Raspberry Pi 64 SL runtime on it. So I've created a gateway (IP address of the Raspberry, TCP port 1217). I see the green dot next to this gateway. When I do a network scan, I can see my raspberry (see photo). When I try to connect to it, I have to define an administrator profile, which I do. On validation, I see a message: No device is responding to the scan request. I've checked that port 1217 is listening on the raspberry, I've uninstalled the runtime then installed it again, but I can't connect. Also, when I try to configure the user groups before connecting, I see that Offline mode is not supported by the device, even though I'm connected to it in the Deploy Control SL tab. When I try to refresh, I see: Gateway not configured properly. How can I connect to my Raspberry? Have I defined my gateway incorrectly?

Post by pppn on Issue with Forward Open Connections in Ethernet/IP Protocol Stack in Codesys ^{CODESYS Forge talk (Post)}
Hello, I am facing an issue with my Ethernet-based project in Codesys. My product was functioning well until I modified the protocol stack and uploaded it to my device. Here are the details of my problem: Project Setup: I am working on an Ethernet-based project to test my product. The project was running without issues before modifying the protocol stack. Issue: After modifying the protocol stack and uploading it to my device, I am encountering an error in Codesys related to the forward open connections. Error status: connection failure, extended: connection in use or duplicate forward open. According to the Ethernet/IP protocol in codesys, there are three forward open connections that need to be established. The first two connections are opening without any issues. The third connection, which is an input-only connection, is causing problems. The error message indicates that the connection is already open. Debugging Attempts: I have extensively debugged the protocol stack and found no issues. The product works well when tested with EIP tools but not with Codesys. Exclusive owner connections are working correctly, and only the input-only connection is problematic. Wireshark Traces: Wireshark traces show that the third connection attempts to open but reports that it is already open. Steps to Reproduce: Modify the protocol stack and upload it to the device. Attempt to establish three forward open connections in Codesys. Observe the error on the third connection (input-only). Request: I would appreciate any suggestions or guidance on how to resolve this issue. If there are specific settings or configurations in Codesys that I need to check, please let me know. Additionally, if there are known issues or workarounds related to this problem, I would be grateful for the information.

Post by imdatatas on MC_CamIn did not work properly with SMC_FreeEncoder on SoftMotion 4.17.0.0 ^{CODESYS Forge talk (Post)}
Hello, I am facing a problem with the new Softmotion 4.17.0.0 version. Has anyone encountered a similar problem, what is the solution? I would be happy if you could share it. Problem description: -- "SMC_FreeEncoder" encoder axis is the master, -- The motor of the servo driver on the EtherCAT bus is the slave axis. -- When the MC_CamIn block executed, the InSync output is activated. However, although the master encoder axis position value changes, there is no movement in the slave servo axis! Test steps: 1-) EtherCAT servo axis installed, configured and motion test was performed with MC_Jog. No problem. 2-) Softmotion general axis pool > SMC_FreeEncoder was added and pulse amount configuration was performed. No problem. 3-) Incremental encoder actual count value was transferred to the "SMC_FreeEncoder.diEncoderPosition" variable as DINT under the ethercat task in every cycle and the encoder axis position value was observed. No problem. 4-) A simple CAM table with a 1:1 ratio was created under the project tree. (For example: Simply, when the encoder rotates 1 turn, the motor will rotate 1 turn.) 5-) The SMC_FreeEncoder axis enabled with MC_Power and brought to the StandStill state. 6-) The MC_CamTableSelect block was run with default input values ​​(all absolute) and only the Cam table name was specified. The Done output was seen successfully. No problem. 7-) The MC_CamIn block was activated with default input values ​​(absolute) and only the master encoder axis name, slave servo axis name, CamTableID input pins was specified and then "Execute" input set to TRUE. 8-) The InSync output information of the MC_CamIn block observed as TRUE. However, although the encoder axis value changed, the position value of the slave axis did not change at all, it did not move. It always remained at 0.0mm. 9-) When I repeated the same steps above, only changing the master axis to SM_Drive_Virtual instead of FreeEncoder and gave movement to the virtual axis, this time the slave axis moved successfully. However, when the same steps and operations are performed with the same IDE just downgrade SoftMotion version from 4.17.0.0 to 4.10.0.0, everything works normally and without problems as expected in MC_CamIn block with FreeEncoder master. (By the way, The used IDE version is Codesys V3.5 SP20patch3.) Best Regards Imdat

Post by jinlee on Multiple WebVisu ^{CODESYS Forge talk (Post)}
Hi, thank you for replying. Basically, I have a main visu with frame selection. So, under some condition the frame will switch to a specific frame. It used to be controlled by variable using "Switch frame variable". However, I realise it will change all the HMI screen at one time. So I removed the variable, and still looking for a solution to do that. Do you have any idea?

Post by mariapaola on Port instantiation of serial interface in WAGO PLC using Modb_L05.lib in CoDeSys v2.3 ^{CODESYS Forge talk (Post)}
Hi, Would really appreciate your insights in this issue I have. I am currently using a WAGO 750-881 with multiple IO devices. For one of them I already occupied the MODBUS Master configuration tool so I cannot overwrite it for my other devices. I have a total of two serial interfaces WAGO 750-652. The first one is instantiated in COM2 and doesn't need any protocol since the information comes in an specific formatting that need little code to differentiate between needed info. This one is working just fine. The second one is where I have an issue. I have tried to instantiate the port using MODBUS library modb_L05.lib to properly receive the data from an ARDUINO and I am absolutely unable to open the port: Signal DEVICE2.fbModbus.MODBUS_EXT_MASTER.Interface.Com_Port_Ist_Offen is never TRUE, among with all other signals from that interface, while signal DEVICE1.COM2.Com_Port_Ist_Offen is TRUE, and the other signals also read as TRUE or FALSE. I have tried instantiating the second one as the first one, changing COM3 to COM4, I've tried a lot of things but it wont ever open the channel. I don't know if you have any recommendations for me. For both physical modules, both witness LEDs A and E are on. First one is instantiated like this: PROGRAM DEVICE1 VAR wBaudRate : WORD := BAUD_9600; bDataBits : BYTE := 8; bParity : BYTE := 0; bFlowControl : BYTE := 3; (RS422 FullDuplex with continous send) i : INT; COM2 : SERIAL_INTERFACE; xOpenPort2 : BOOL := TRUE; ( Flag to open the Port ) xInitPort2 : BOOL; ( Flag to initiallize the Port ) ReceiveBuffer2 : typRing_Buffer; END_VAR COM2( bCOM_PORT_NR := 2, cbBAUDRATE := wBaudRate, cbsBYTESIZE := bDataBits, cpPARITY := bParity, csSTOPBITS := STOPBITS_1, cfFLOW_CONTROL := bFlowControl, utRECEIVE_BUFFER := ReceiveBuffer2, ptSEND_BUFFER := ADR(SendString2), xINIT := xInitPort2, xOPEN_COM_PORT := xOpenPort2, iBYTES_TO_SEND := LEN(SendString2)+1, xSTART_SEND := xSendActive2 ); Second one like this: PROGRAM DEVICE2 VAR COM4 : SERIAL_INTERFACE; xInitPort4 : BOOL := TRUE; xOpenPort4 : BOOL := TRUE; ReceiveBuffer4 : typRing_Buffer; fbModbus : MODBUS_EXTENDED_MASTER_RTU; fbError : enumMB_ERROR; stQuery : typModbusExtendedQuery; stResponse : typModbusResponse; au16Data : ARRAY[0..14] OF WORD; i : INT; tPoll : TON; END_VAR COM4( bCOM_PORT_NR := 4, cbBAUDRATE := BAUD_9600, cbsBYTESIZE := 8, cpPARITY := 0, csSTOPBITS := STOPBITS_1, cfFLOW_CONTROL := 2, ( RS-485 half-duplex ) utRECEIVE_BUFFER := ReceiveBuffer4, xINIT := xInitPort4, xOPEN_COM_PORT := xOpenPort4, xSTART_SEND := xSendActive4, ); stQuery.SlaveAddress := 1; stQuery.FunctionCode := 3; stQuery.Read_StartAddress := 0; stQuery.Read_Quantity := 15; (Poll code) fbModbus( ENABLE := TRUE, bCOM_PORT := 4, ( COM4=> 750-652 port ) cbCOM_BAUDRATE := BAUD_9600, cpCOM_PARITY := 0, csCOM_STOPBITS := 1, cbsCOM_BYTESIZE := 8, cfCOM_FLOW_CONTROL := 2, TimeOut := T#500ms, StartFunction := xStart, ExtQuery := stQuery, Response := stResponse, MB_Error => fbError ); FOR i := 0 TO 14 DO au16Data[i] := stResponse.Data[i]; END_FOR;
