Go in Windows to this location. Right click on this file and go to properties. Is it in Read-only state? Then CODESYS cannot open in Write mode.

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...

ok now it is clear - this is a single core Pi Zero W. For this device there is no edge device available. But just for working with CODESYS it is not really needed and yes plc runs only for 2h unlicensed.

Do not filter on Phoenix devices. First add an Ethernet device (from CODESYS). Then add a Profinet Controller (from CODESYS). Then add your Phoenix devices to this CODESYS Profinet Controller.

Hi there, I am having a similar problem like you. I have 3 screens connected to one PLC. I have set 3 different URLs for them. But 3 of them are still dependent to each other. How can I make them independently ? Kind regards, Jin.

Post by oi18ct on ARM SL Development Board Recommendation ^{CODESYS Forge talk (Post)}
Hello codesys forum, My company is looking at developing a solution with Codesys ARM SL. The requirements will not tax the capabilities of Codesys. I would like to buy an AMR 7 or 8 Dev Board for experimenting. I am looking for a recommendation as I have minimal experience with Linux. Any input from the forum would be most appreciated as the hardware requirements as provided by Codesys for ARM SL seem pretty minimal (basically a arm7 or 8 with Debian is all). Our needs are small in scale- something like 8 digital inputs, 6 digital outputs, 2 analog inputs and 1 analog output. A small gui will be published via web visualization for external display (no local display). Communications with ModbusTCP and uart/RS485. It may be necessary to access i2c and make c or python calls to some existing code that is pretty small. Something like the EMCraft STM32MP1 SOM Starter Kit or Octavo Systems OSD32MP1-RED development board? Ideally something that has a path to a SoM for production. Kontron appears to have some interesting options too. Just having a hard time deciding where to start. Thanks in advance... LC

Post by antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers ^{CODESYS Forge talk (Post)}
Looking for thoughts on creating libraries that can be used on both 32-bit and 64-bit controllers. We are currently writing software in CoDeSys for both target types and will continu to do so for the near future. Projects are always unique, no straight forward copy/paste, yet there is enough similarity between them to use libraries for recurring logic. I do not want to create and maintain twice for both platforms if this is not absolutely necessary. I am aware of useful datatypes like __XWORD, __XINT, __UXINT. Still looking for more information and/or sample code for portable pointer arithmetic. In addition to that: how should one go about when creating and working with compiled libraries? Would I need to compile the same lib twice, once for 32-bit targets once for 64-bit targets? I would end up with two different libs with the same namespace, which does not sound elegant to me. Note: I did not intentionally make the previous paragraph bold. The forge forum software seems to do this automatically upon insertion of a word which starts with two underscores, e.g. __XWORD (yeah, here we go again :) )
