A clean sequential control program for a chemical mixing tank in CODESYS 3.5 is right in my lane, since my background is chemical engineering and I think in terms of process steps, dosing, mixing, and the logic that ties them together. I will build a simple, well structured step-chain program for the dissolver, with a clearly laid out input and output structure and a control sequence that is easy to follow from one step to the next. It will be clean enough to use as a small demonstration project, where anyone reading it can see exactly how the logic moves through fill, dose, mix, and discharge without getting lost. My chemical engineering grounding means I understand the actual process behind the program, not just the code, so the step logic reflects how a real mixing and dissolving sequence behaves. Tell me a bit about your tank setup, the inputs and outputs you have in mind, and how detailed you want the demo to be, and I will map out the step chain and structure for you.

Hi, As a Master’s graduate in Automatics and Systems, I specialize in building clean, industrial-grade state machines and step-chain logic using CODESYS 3.5.I will develop a highly structured, easy-to-understand sequential control program for your chemical mixing tank using Sequential Function Chart (SFC) or Structured Text (ST) based on your preference, making it perfect for a demonstration project. My Execution Plan (Under 1,500 characters): ✅ Architecture & I/O Structure: I will define a clean, modular I/O mapping structure (Inputs: Level Sensors, Temperature, Emergency Stop; Outputs: Fill Valves, Agitator Motor, Drain Valve). ✅ Step-Chain Logic: I will implement a robust state machine covering the complete sequence: Filling $\rightarrow$ Heating/Mixing $\rightarrow$ Draining $\rightarrow$ Standby, with explicit transition conditions. ✅ Safety & Interlocks: I will embed basic fault-handling logic (e.g., timeout faults if a valve sticks) to demonstrate industry-standard safety practices. I will deliver a fully functional CODESYS 3.5 project file (.project) with heavily commented code, ready to run in simulation mode or on actual hardware. Let's connect to finalize the step sequence and get this built for your demonstration. Best regards, Zakaria L.

@SkillCrafts

Your requirement for a clear, structured CODESYS 3.5 step-chain program for a chemical mixing system immediately brings to mind similar projects where I've implemented state machines for process automation, ensuring robust control and easy diagnostics. The emphasis on a clean, demonstrative solution aligns perfectly with my approach to developing maintainable and understandable PLC code. My technical approach will involve leveraging CODESYS's built-in Function Block Diagram (FBD) or Structured Text (ST) for the step-chain logic, ensuring clear visualization and execution flow. I'll meticulously define input/output mapping using standardized naming conventions, likely within a dedicated `GVL` for clarity. The core logic will be encapsulated in a reusable function block for the step-chain, with clear transitions and actions for each state (e.g., filling, mixing, discharging). Error handling and safety interlocks will be integrated as distinct states or sub-routines. To ensure we're perfectly aligned, could you clarify if there are specific safety SIL requirements for this system, and what level of detail is expected in the user documentation for this demonstration project? I'm confident I can deliver a high-quality, easy-to-understand CODESYS 3.5 step-chain solution. Let's schedule a brief call to discuss the specifics.

@lisap305

Hello, I am a control systems engineer with extensive experience in CODESYS 3.5 and chemical mixing applications. I will create a clean, understandable sequential control program for your dissolver system using Sequential Function Chart (SFC) or a well‑structured ladder/ST implementation. The program will include: (1) step‑chain logic (e.g., fill, mix, drain, rinse), (2) clear I/O mapping (sensors, valves, agitator), (3) interlocks and safety checks, (4) manual/auto modes, (5) simple HMI visualisation (web visualization or basic panel). I will deliver the project file (.project), commented source code, and a short documentation explaining the sequence and I/O. I have done similar chemical mixing PLC demos. Estimated timeline: 3–5 days. Best regards.

@nimran54

Hey , I am a US based Freelancer, I just finished reading the job description and I see you are looking for someone experienced in Mechanical Design, Electrical Engineering, Industrial Engineering. This is something I can do. I will build a clean CODESYS 3.5 PLC step chain for the chemical mixing tank / dissolver system with clear states, inputs, outputs, and a simple sequential control structure that is easy to follow in a demo project. I can organize the logic so each step is readable, commented, and suitable for showing the full control sequence from start to finish. To start, I need your process sequence, required sensors and actuators, any safety interlocks, and the preferred step order. Drop me a message before placing an order price can be discussed after discussion.

@DavidPLC1

I’ve been working with CODESYS 3.5 for a while now, and designing sequential controls batch is my space. For a batch/dissolver system like this, using SFC (Sequential Function Chart) structure is definitely the best approach. It makes the step-chain logic, transitions, and I/O mapping incredibly easy to follow and troubleshoot which is perfect for a clear demonstration project. Let’s have a quick chat to define the exact sequence of your tank (valves, mixing time, heating, etc.) and I can get started right away.
