Post by eoahe on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hey Guys :) I have the following Problem using Modbus via Codesys: I'm trying to implement a Modbus Device into my codesys project. The device is a Router from Teltonika (RUT956) and it can communicate via Modbus. Currently I'm trying to implement it into my codesys prject as a slave and I'm using my windows computer as master. As it is not a codesys device (the codesys application is not uploaded to device as it has its own software) I'm having problems requesting and reading registers from the router. I've set up my windows computer as Master and implemented the router as slave. When I go online on my master device it sais that it has established a connection to the slave (router)(So I'm thinking this could work as there is a connection?). The goal is to read the GPS (latitude and longitude) data and on the homepage of teltonika you can find the register address and number of registers (adress 143 for latitude and 145 for longitude; both have a number of two registers). I've found tutorials how to read specific registers via their register address with other modbus programs (like modbus-cli), but as my entire project is established in codesys I was hoping to read these specific registers via codesys so that I can show the GPS data on my dashboard. I've tried establishing slave channels but that hasn't been working. I tried read input register channels of the length 4 but it's not possible to define specific register addresses to read via codesys so that didn't work (I jsut get a slaves device failure) and I've also tried establishing 516 (total number of registers the router sends I think?) read inputregister channels but that has the samle failure... So i guess the problem I'm having is establishing slave channels to read these specific registers. Does anyone know how to tackle this problem and has maybe had the same problem? Or maybe someone knows a workaround? I'm quite new to codesys so maybe I'm also lacking expertise...

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. Attachments: Wireshark traces showing the connection attempts and errors Screenshots of the error messages in Codesys codesys version: CODESYS V3.5 SP16 Patch 3 + 64 bit
