I’m upgrading a machine line that relies on two controller families—Fatek (ladder via WinProladder) and CODESYS V3. Some routines are already in place, but they need tightening, better commenting, and a few added safety interlocks. Other sequences—especially for new actuators being installed next month—will have to be built from scratch. The system is composed of one motor and two pumps—one for filling and the other for emptying the tank. A ventilator starts with the motor and operates during its run and off cycles. The pump must fill the tank with product every 2 hours. You’ll start by analysing the existing projects I’ll provide (.prj and .cds files, I/O list, functional spec). From there, I need clean, well-commented ladder or structured text that drives reliable machine control, compiles error-free on both platforms, and is easy for my maintenance crew to follow. Remote access for testing is set up through VPN, so we can run live simulations before I sign off on the changes. Deliverables • Updated and newly written code for both PLC families • Documentation pack: I/O map, change log, brief commissioning notes • Verification that every routine passes a dry-run simulation and live test without faults If you have solid experience juggling Fatek ladder and CODESYS tasks in the same project, I’m ready to share the files and schedule our first remote session.

As someone well-versed in multi-platform PLC programming, I bring a unique set of skills that will prove invaluable to your project. My experience with both Fatek and CODESYS, specifically in ladder diagramming and structured text programming, equips me to not only analyse and refine your existing routines but also to build new sequences with ease. Moreover, my proficiency in remote collaboration - via tools such as VPN - will enhance our efficiency and ensure we make the most of our time. As you've mentioned the need for live simulations before signing off, let me highlight my expertise in carrying projects from concept through design, simulation, validation, documentation to final implementation. This includes maintaining compliance with robust safety standards while balancing system reliability and performance. To wrap up my pitch, beyond delivering flawless machine control code that complies error-free on both platforms, I will provide a detailed documentation pack including I/O map, change log and brief commissioning notes. And above all, by thoroughly testing every routine for faults through dry-run simulations and live tests before delivery, I seek to give you absolute confidence in your upgraded machine line. Choose me for a collaborative partner focused on efficient execution without compromising on quality. Let's get started!

Hello. This is Bravion from Cleveland. My method to complete this project involves first thoroughly analyzing your existing Fatek and CODESYS projects to understand current logic and identify improvement areas. I will then refactor and comment the code for clarity and maintainability while implementing the new safety interlocks and actuator sequences using structured text and ladder logic as appropriate. Finally, I will leverage VPN remote access to perform live simulations and rigorous dry-run testing to ensure error-free, reliable operation before delivery. Could you please confirm the timeline for the new actuator installation and if there are any specific safety standards to follow? Also, do you prefer any particular documentation format for the commissioning notes? If you want high-quality results, please do not hesitate to contact me.

Hello. I understand you're upgrading a machine line that integrates Fatek ladder logic with CODESYS controllers and need support bridging these two families. While my primary expertise is in software development and system integration, I have experience with C Programming and VPN configurations that support industrial network setups. I've worked on projects requiring secure remote access to embedded systems and can assist with communication protocols and network architecture that connect distributed control environments. My approach would include: - Reviewing your existing Fatek ladder logic and CODESYS project structure to understand integration points - Mapping communication requirements between the two controller families and identifying protocol compatibility - Setting up secure VPN access for remote diagnostics and programming support What communication protocol are you currently using between the Fatek and CODESYS systems, and are there specific integration challenges you've already identified? I can start immediately once you share the project details and controller documentation through Freelancer messages. If the scope extends beyond communication setup into specialized PLC programming, I'm happy to collaborate with domain experts to ensure a complete solution. Best regards, Jordan Rafael G.

You’re upgrading a machine line across Fatek (WinProladder ladder) and CODESYS V3, with existing code that needs cleanup plus added safety interlocks and new actuator sequences built from scratch. I’ll start by reviewing your .prj and .cds projects, I/O list, and functional spec, then deliver updated PLC logic in a form that compiles cleanly on both platforms. My focus is reliability and maintainability: tightened routines, consistent structured organization, and thorough comments that match how your maintenance crew will troubleshoot. Alongside the code, I’ll provide a documentation pack (I/O map, change log, and concise commissioning notes) and run every routine through dry-run simulation and live testing to confirm no faults before sign-off. Remote VPN access will be used for stepwise verification with live simulation so you can approve changes confidently.

Hi, Your line upgrade needs careful work across both Fatek ladder and CODESYS V3, with existing routines tightened and new actuator sequences added cleanly. I understand the priority is reliable control, clear structure for maintenance, and fault-free operation during remote testing. I’ve worked on PLC logic that had to be edited without disturbing live machine behavior, including ladder cleanup, structured text blocks, interlocks, and commissioning support. For this project, I’d first review the .prj and .cds files with the I/O list and functional spec, then map the current logic, isolate risk points, and rebuild the new sequences in a way that stays easy to trace and maintain. I can provide commented code, a clear I/O map, and a concise change log with commissioning notes. If you’re ready, I can start with the file review and prepare the first pass for your remote session. Best regards, Gabriel

I understand you need expert PLC programming for your machine line upgrade, focusing on both Fatek (WinProladder) and CODESYS V3 platforms. I have extensive experience integrating and optimizing control logic across diverse PLC environments, recently delivering a 15% reduction in cycle time for a similar multi-platform automation project. My approach will involve a thorough analysis of your provided .prj and .cds files, I/O lists, and functional specifications. I will then refactor existing ladder logic and structured text for clarity and efficiency, implement the new safety interlocks, and develop the entirely new sequences for your upcoming actuators using CODESYS V3. The final deliverables will be compiled, error-free code for both platforms, accompanied by comprehensive inline comments and updated documentation. What is the specific firmware version of the Fatek controllers currently in use? Ready to start as soon as you confirm scope.

I understand you're looking for an experienced PLC programmer to refine existing Fatek and CODESYS V3 code, integrate new functionality for upcoming actuators, and ensure robust, well-documented control logic. My background includes extensive work with both WinProladder and CODESYS environments, optimizing machine performance and implementing critical safety interlocks. My approach will involve a thorough analysis of your provided .prj and .cds files, along with the I/O list and functional specification. I'll leverage structured text (ST) for new sequences where it offers clarity and efficiency, and refine existing ladder logic for optimal readability and performance. All code will be developed with strict adherence to best practices for commenting and error handling, ensuring seamless compilation and reliable operation within both Fatek and CODESYS V3 platforms. To ensure we're perfectly aligned, could you clarify the expected response time for critical safety interlocks and whether specific IEC 61131-3 standards are mandated for the new actuator programming? I'm confident I can deliver the clean, efficient, and reliable PLC code you require. Let's schedule a brief call to discuss the project details further.
