PLC & SCADA Jobs

I'm seeking a skilled PLC programmer to develop a control system for an ammonia refrigeration setup. The system will manage: - Compressor start/stop and capacity control - Condenser fan and pump control - Evaporator cooling and defrost control Requirements: - Control of the complete system (compressors, fans, pumps, evaporators) - Integration with existing setup (basic schematics provided) - Only 120 volt control of starters and related equipment is needed Ideal skills and experience: - Proficiency in PLC programming (Siemens, Allen-Bradley, or Schneider Electric) - Experience with refrigeration control systems - Ability to read and interpret basic schematics - Electrical engineering background is a plus Please provide relevant experience and approach to the project in your bids.

I need an experienced PLC programmer to troubleshoot and maintain a Mitsubishi PLC system in Pune. You will work with full documentation and codes. Key requirements: - Expertise in Mitsubishi PLC, preferably FX, Q, or iQ-R series - Strong troubleshooting skills - Familiarity with reading and interpreting PLC documentation and codes - Ability to work on-site in Pune

We are from SYNOD BIOSCIENCE and doing a project with an MNC for which we required an electrical engineer for a biogas-based plant project. We are looking for a freelance electrical engineer to develop complete electrical and instrumentation design based on the provided P&ID and vendor documents. The scope includes electrical load calculation and cable sizing, preparation of SLDs (PCC, MCC, and overall plant), GA drawings for MCC and synchronization panels, cable schedule and routing layout, MCC and control panel design, and synchronization system for the biogas genset. The role also involves PLC-based automation design including IO list, control philosophy, and interlocks, along with instrumentation integration as per the P&ID. Additionally, earthing, lighting, and cable tray desi...

I have a new industrial control system under development and now need the core PLC program written from scratch. The hardware has already been selected; I can share the full I/O list, functional specification and any wiring drawings you require once we start. Your role will be to translate those documents into a clean, well-structured PLC application, fully commented and ready for download to the controller. I’ll also count on you to: • model or simulate the logic so we can prove operation before installation • make reasonable tag-naming and memory-usage choices to keep future maintenance simple • supply the compiled program, the editable source file and a quick hand-off guide that explains each routine If you can stay available for remote support during first...

The project revolves around a Kinco PLC linked to its HMI, all developed in the D-Tool suite. I need the controller to handle three core jobs simultaneously: log key process data to non-volatile memory or an external database, push that data to a remote dashboard for live monitoring over TCP/IP, and execute closed-loop automated control of the machine. Connectivity is critical. The program must speak standard TCP/IP for the plant network and support both CANopen and raw CANbus frames so it can exchange data with existing field devices and a supervisory gateway. On the I/O side, the PLC will gather readings from temperature, pressure and proximity sensors, plus capture motor-RPM feedback for speed regulation. The logic should scale, so clean tag structures, well-commented code and clear H...

I’m setting up an Eaton 93 E 40 kVA UPS paired with Ritar 80 Ah, 12 V batteries to keep our data-server room running smoothly when the grid fails. The goal is simple: dependable backup power for critical systems, with 1–2 hours of autonomy, no less. Here’s what I need from you: • A clear calculation of how many Ritar 80 Ah batteries (and how many strings) are required to reach the target runtime, taking internal losses and realistic load profiles into account. • A single-line wiring diagram that shows series/parallel connections, breaker sizes, and recommended cable gauges. • Step-by-step commissioning notes—everything from initial battery charging, through Eaton 93 E parameter settings, to a final acceptance test plan. • A brief maintenan...
