Hello, were I have find varaible of SYNC "Cycle Period" , or variable that informs about the start of a new cycle SYNC. I want to use this variable in program code. I need to for communication beetween Mster and slave, and send PDO informations.

Turns out Modbus was working despite the pre-compiler errors; I was reading the wrong addresses of the slave device, which was why I was seeing all 0s. Thanks for ignoring me.

Post by arundara on Variable Sync Issue In Soft Plc Redundancy
CODESYS Forge

(Post)
Hello, I was trying to create a redundancy POC for our application where we read data from few modbus tcp devices. As there is a limitaion that modbus tcp device support only for single master device, we wanted to test how the variable sync happens in redundancy mode. For that i have used the redundancy sample code added a variable "b" under a condition. What i observed was while active controller is running, if passive controller is powerup, passive controller is able to sync all the data configured for redundacny. But after that the variable data which resided under a condition is not synching from active to passive controller. I have attached the image where i have highlighter the variable. Can some help me to understand how redundacny work in codesys soft plc and if there is a solution to sync variable which are under condition, please explain the same or suggestion to achieve the same. Hardware - Raspberry Pi (2 qty) Redundancy licence used - yes in both controllers. Codesys runtime - 4.9.0.0 Codesys software version - V3.5 SP19 if i have posted this question in wrong section, please do let me know in whcih section i have to post this question.

Hi Artur, as mentioned by imdatatas, homing when not enabled is not supported in SoftMotion. If enabling before homing is not an option, an alternative might be controller based homing using MC_SetPosition. Best regards, Georg

Hi all, for a new project I'm looking for a redundant controller with EtherCAT fieldbus I/O. Actually I'm using Beckhoff and it works great! but there's not a solid redundancy yet... Does someone get experience for industrial application (not raspberry) for a redundant Codesys system? If yes please share some info (CPU / OS type, bus, number of managed I/O,... and especially feeling feedback (stability, bugs, performance)... Every suggestion is kindly appreciated!! Fabrizio

1) Based on your first screenshot. Do NOT filter on "Phoenix". Then first select the Ethernet adapter (of CODESYS) and add this to your device. 2) Then to this Ethernet adapter add a Profinet Controller of CODESYS. 3) Then to this Profinet Controller, add your Phoenix Profinet coupler/adapter.

CODESYS Forge

(Post)
Hello everyone, I am currently working on reading data from energy analyzers using Modbus TCP and RTU (RS-485). In my previous software, I used the following method to add slave devices (i have attached the image) and configure registers: Add the Modbus slave device. Configure the communication parameters (baud rate, parity, etc.). Define the registers and their addresses for data retrieval. Now, I am trying to achieve the same in CODESYS 3.5, but I am not sure how to configure the Modbus master, add slave devices, and set up the registers properly. If anyone has experience with Modbus TCP/RTU setup in CODESYS 3.5, I would really appreciate your guidance! A step-by-step explanation or any references/tutorials would be extremely helpful.

If you have a Windows system (RTE), then why not run the CODESYS HMI as separate controller. This could easily be moved to another PC if required. In the HMI you could also still use the Symbolic Var access as part of the Data Source Manager, although maybe OPC is the preferred way to make it more future proof. Or what about the Remote Target Visu. Then you can reduce the load of the main controller, while still only having to create one application including Visualization. This is now also supported for Linux systems. See: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_target_visu_for_linux.html https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_execute_remote_target_visu.html

Iv been working with a Deep Sea Electronics DSE840 for about 6 months. I have a development version of my program working with a state machine and a basic gui interface. I went to implement CAN and suddenly the text on the gui on the controller is much larger than before. I could flash old versions of my project and the text was the correct size, but if i renamed the project file, the text displayed would be large. The visualization in CODESYS always shows the expected size, but not the controller. I did a fresh install of CODESYS and even a new project with only one text box, I cant get the text size on the controller to match what is displayed in codesys to match. Any advice?
