Post by janber0206 on RPI is license server down ^{CODESYS Forge talk (Post)}
I had the same problem. Problem solved: all licences purchased before October 2022 must be updated by Codesys. To do so, simply contact the support in the Codesys Store.

I'm now circumventing the problem by creating a separate TCP client for all Write actions. Upon registering a changed variable, I enable this client, until the change is processed.

Post by hanpekel on Reading request counter value from modbus server in application ^{CODESYS Forge talk (Post)}
Any way I can read the value of the 'request counter' (see screenshot) in my application. Amount of client connections is easily found using ModbusTCP_Slave_Device.uiClientConnections; But for request counter it does not seem to be that simple.

means not licensed demo mode.. use the Licenserver on the host and apply a license and add the Ip of the license server then it will be green.

Yes, this is possible with the Toolkit. We only server customers in the Benelux that do this, so contact your local CODESYS distributor, or contact the sales team of CODESYS Germany.

Post by rjwkerkhof on IIot Libraries SL --> Web Socket Client SL Pong issue ^{CODESYS Forge talk (Post)}
Dear all, I am developing a Web Socket Client in Codesys 3.5 using the Web Socket Client SL library to retrieve data from a third party. Connecting and reading works fine however after 40 seconds the connection gets interrupted by the server due to keepalive ping timeout. After discussion with third party it seems that the Web Socket Client SL library replys to the Ping request of the Web Socket server BUT does not add the "Application data" = 4 bytes in the body of the Pingframe to the Pongframe. Therefor the server does not recognize the Pongframe send by the Web Socket Client SL library and automatically disconnects. Is this a known issue with the libary or am I doing something wrong? Is there a workaround to add the 4 bytes manually to the Pongframe before replying it to the server? Thanks in advance, Roy

Are you sure you need to read holding registers? Have you tried reading input registers?

Post by fleaplc on Modbus TCP Server connection is ESTABLISHED but all holding registers are value 0? ^{CODESYS Forge talk (Post)}
Did you check the communication with a sniffer ? (ex. Wireshark) to check if the holding get to zero by a wrong writing (client initialization?) o something else?

Post by pra83 on CODESYS SoftRedundancy — Both PLCs stay standalone after network interruption — Auto recovery not working ^{CODESYS Forge talk (Post)}
Hello, We are facing a critical issue with CODESYS SoftRedundancy that we have been unable to resolve despite extensive troubleshooting. HARDWARE: 2× HP EliteDesk 800 G9 SFF Intel Core i7-14700 (20 cores) 16GB RAM, 512GB NVMe SSD Windows 11 IoT Enterprise LTSC 2024 NIC1: Built-in Intel GbE NIC2: Intel I210-T1 PCIe (NIC team) SOFTWARE: CODESYS Control Win V3 - x64 Version 3.5.22.10 CODESYS SoftRedundancy SL Server 1 IP: 172.10.10.101 (PLC1 — Active) Server 2 IP: 172.10.10.102 (PLC2 — Standby) CURRENT CODESYSControl.cfg: [CmpRedundancy] BootupWaitTime=120000 StandbyWaitTime=12100 SynchronousTimeout=12100 [CmpSchedule] ProcessorLoad.Maximum=80 WatchdogTime=12000 WatchdogTimeoutAction=0 CONFIRMED WORKING: PLC1/PLC2 identification configured via IDE Connection IP configured via IDE AutoSync enabled and written via IDE Normal Active/Standby operation working Server 2 auto-promotes when Server 1 completely fails PROBLEM DESCRIPTION: When NIC1 cable is removed from Server 1 — both servers go to standalone mode. When NIC1 cable is reconnected — both servers remain in standalone indefinitely. Neither server auto-recovers to Active/Standby without manual CODESYS service restart. AutoSync fires (!!! Autosync !!! visible in log) but recovery does not complete. Tested with direct cable (no NIC team) — same result. Confirmed not a hardware or NIC teaming issue. KEY LOG MESSAGES: "Timeout: No sync message RMSG_StartCycle (5) from master: Standalone" "Socket on other side closed gracefully 0" "Standby PLC: Open acyclic work socket failed" "Connection broke after 11806ms. Check BootupWaitTime." Autosync(fires but does not complete recovery) PCAP ANALYSIS (Wireshark): CODESYS sync stops completely at T+3s Server 1 sends TCP FIN on ports 1206 and 1208 at T+5s No CODESYS redundancy traffic for remaining 24 seconds Both servers stay standalone indefinitely WHAT WE HAVE TRIED: StandbyWaitTime = 12100ms SynchronousTimeout = 12100ms WatchdogTime = 12000ms (less than StandbyWaitTime) AutoSync enabled NIC2 set as Standby adapter Disabled Windows Network Discovery Direct cable test — rules out NIC hardware QUESTION: Per official CODESYS documentation: "No automatic Reconnect is included in the functional scope of the redundancy components. You can program the triggering of a reconnect." Is RDCY.Synchronize() the correct function to add to our application for automatic recovery after both PLCs go standalone? What is preventing auto-recovery when AutoSync is enabled and PlcIdent is correctly set? Thank you for your support.

Post by thn-power on Codesys Communication Manger - Required information model version exists in the model repository but is not found ^{CODESYS Forge talk (Post)}
Hi. Thanks for the answer. I think I found your post on the Wago forum. I have tried installing all different nodeset versions of the opcfoundation.org/UA but neither work. Though I could not find the nodeset version called 15.09.2021 anywhere online. The opcfoundation repository only goes back to version 1.04.11 2022-03-29. Also wondering how I can generate a custom information model that only refrences the latest version of nodesets?

Post by manuknecht on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
I managed to find a solution that seems to work reliably. As the VU.Globals.CurrentClient-filter accesses the CURRENTCLIENTID or at least a similar, internal variable it can only be used if called from a certain client (e.g. from a button in a visualization). My solution works by implementing a new client filter that compares the client ID of all clients to the ID of the last client that was used. The variable containing the data of the last client is defined as: G_LastClient : VU.IVisualizationClient; // Copy of last client that detected click This last client is then updated every time a button is pressed using the Execute ST-Code input configuration of the button: G_LastClient := VU.PublicVariables.Clients.Current; Next, I created a function block that implements the client filter interface as so: FUNCTION_BLOCK FB_LastClientFilter IMPLEMENTS VU.IVisualizationClientFilter VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR END_VAR Then i added a method to the FB called IsAccepted which is used to filter out the client. When creating the method, it should automatically be filled with the according variable declaration, as it is defined in the interface: (* For every client can be desided, if it is accepted. ``TRUE``: Client is accepted*) METHOD IsAccepted : BOOL VAR_INPUT (* The client, to check*) itfClient : VU.IVisualizationClient; END_VAR Now the client can be compared to the last used client as such: // check if clientID corresponds to clientID of last recorderd client IF itfCLient.ClientId = G_LastClient.ClientId THEN IsAccepted := TRUE; ELSE IsAccepted := FALSE; END_IF To make use of this custom client filter, initialize a variable with the client filter: LastClient : FB_LastClientFilter; // Client filter to find last used client Then use this client filter when opening or closing a dialog from ST: fbOpenMyDialog(itfClientFilter:=LastClient,xExecute:=TRUE,sDialogName:='VIS_MyDialog_DLG');

Post by hwopereis on How to use Application Trigger in Modbus TCP Server ^{CODESYS Forge talk (Post)}
Hi, I'm currently reading and writing several registers with a Modbus TCP server as a subdevice of a Modbus TCP Client. If I read and write cyclically, there are no issues. The problem is this: I see there is also the option to write by "Application", which I would like to use. However, I don't know With the Modbus RTU client, I see there is a trigger variable, xTrigger, to trigger the writing tasks. However, I can't find any such trigger for the Modbus TCP Client. Does anybody know how to implement the trigger behavior for the Modbus TCP client? In particular, I struggle to find the exact "trigger" variable. I'm running Modbus Client version 4.4.0.0 Thanks in advance!

Post by yannickasselin on codesys VLAN tagging ^{CODESYS Forge talk (Post)}
Hi, I am looking for exactly the same thing. I would think that using a layer 2/3 managed switch should work but I am not convinced. I would like to test it in order to see if it would be possible to run many Codesys Docker instances on a server and run only 1 ethernet cable from the server to a managed switch closer to the machines beeing controlled instead of having to run multiple long ethernet cables. I was going to buy a managed switch in order to test it but I want to first make sure it is possible and I want to figure out exactly what kind of switch I would need. Is this even possible? I think this is a feature that would be very useful paired with "Codesys Virtual Control SL". Thank you

Post by timvh on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
According to the documentation: https://wiki.teltonika-networks.com/view/RUT956_Modbus You need to create a Channel to read 2 registers from address 143 to get the lattitude. It doesn't specify if you need to read it as a Holding Register or as an Input Register. You could try both. So in the Teltonika router, you need to enable it as being a Modbus Server. Then in CODESYS add an Ethernet Adapter, then a Modbus Client (Master) and to the Client (Master) add the Modbus Server (Slave). Set the IP address and add the Channel. The please consider that CODESYS doesn't update any variables when they are not used in the application. In the I/O mapping tab of your I/O configuration, you can set the "Always update" to enabled.

Post by rafa on MODBUS TCP SERVER DONT AUTO-STARTUP ^{CODESYS Forge talk (Post)}
Dear all, I have a project where I have two ModbusTCP communication drivers in the application. It's working normally until a power outage or the installation panel is restarted. As soon as the PLC CPU is restarted, the Ethernet port is OK, but the TCP Server displays an "UNDEFINED" error. I can't reset the error using the diagnostic confirmation or the "mbserver.xConfirmError" bit. I noticed that the error only appears in the "mbserver.byModbusError" memory and the description is "UNDEFINED." The "mbserver.xError" memory doesn't flag an error. When using the warm restart function and then START CPU, the devices return to normal operation. The following demonstration images; The main question is: How can I make devices boot automatically?
