PLC Jobs

I need one experienced PLC engineer to join our commissioning crew on-site for roughly 15 consecutive nights (16:00–24:00). The equipment mix is a backlight-assembly machine paired with a roller-conveyor line, all driven by Keyence PLCs. What you’ll actually do • Take the partially written specifications we supply, fill the gaps, and build fully functional programs for both the backlight machine and the conveyor line. • Load, test and fine-tune those programs on the factory floor until the machines run to target cycle time and quality without alarms. • Work side-by-side with our existing commissioning team, but operate independently when required; I’m counting on your proven project experience to keep nightly progress on track. Key expectations &b...

I need a complete design—and, if you can, a prototype plan—for an automated potato sorter that separates crop primarily by size but can also flag colour blemishes, shape inconsistencies and any bruising or damage. Target throughput is about 10 tonnes per hour, so the system has to run fast and stay reliable in a dusty, damp pack-house environment. The core assignment is the engineering: conveyor layout, singulation, sizing mechanism (rollers, screen, optical gates—whatever you know will achieve clean size grades), plus a vision or sensor module that triggers reject lanes for defective tubers. I’m flexible on whether you prefer PLCs, Arduino-class micro-controllers or an industrial PC, so long as replacement parts are easy to source and software is clearly documente...

I need a TIA Portal project that handles all PLC programming for an S7-1500 controlling a robotic cell. The mechanical side is already in place; what is missing is structured, well-documented ladder or structured text logic that manages motion coordination, I/O handling, safety interlocks, and fault diagnostics. I will supply the tag list, network layout, and the robot controller’s handshake requirements. Your task is to build the PLC program in TIA Portal (current V18) and return the complete project archive along with a short commissioning guide. Please keep the code modular so later changes—such as adding stations or extra safety zones—are straightforward. Acceptance will be based on: • Program opens without errors in TIA Portal V18 • All handshakes pass...

I need an experienced cybersecurity engineer who knows how to secure manufacturing OT environments from the ground up. Our plant floor runs a mix of SCADA, PLC and DCS systems on VMware / ESXi virtual infrastructure, and I’m kicking off a project that tightens every layer—from the hypervisor to the operator workstation—while staying fully aligned with ISA/IEC 62443 and NIST guidelines. Scope of work • Assess the present security posture, map risks to ISA/IEC 62443 zones & conduits, and deliver a concise risk report. • Recommend and implement security improvements that will not disrupt production or existing integrations. • Verify every change through functional testing and validation before sign-off. Core technical tasks • Deploy and tune...

I need a clean, well-commented ladder program built in Connected Components Workbench for an Allen-Bradley Micro 850. The code will control a short conveyor section that feeds a product flipper and then sends the item out the opposite end. The hardware is already defined: we’ll be using photoelectric sensors for all product detection, and the PLC must honour both an Emergency Stop line and the required safety interlocks. I’ll supply the full I/O list, sequence of operations, and any timing details the moment we start. What I expect from you • A CCW project file containing the ladder logic, organised and labelled so future fault-finding is straightforward • Comments on every rung that explain the intent, tied back to the step numbers in my functional description ...
