Cooking Oil Dispenser – Control System D

Project: Cooking Oil Dispenser – Control System Design & Integration I have a project that requires assistance with the design, programming, and integration of a control system for an oil dispensing truck. Project Overview The system consists of a 24V DC Allan Bradley 8100 PLC and panelview HMI that will control and monitor the oil dispensing process. The truck dispenses multiple types of cooking oils and collects used oil. The control system will interface with multiple sensors and actuators, as described below: Hardware & I/O Requirements Flow Meters (4) – For dispensing new oil (4-20 mA signals). Load Cell (1) – For final weight measurement before dispatch (4-20 mA). Incoming Flow Meter (1) – For used oil collection (4-20 mA). Solenoid Valves (2) – 24V DC operation. Pumps (4) – 0.5 kW, 240V AC, driven by 24V coil contactors. Existing Control Panel – Already built, the current PLC needs to be replaced. Required PLC I/O: 12 DI (digital inputs) 12 DO (digital outputs) 8 AI (analog inputs) 2 AO (analog outputs) Communication The PLC will communicate via Modbus protocol. HMI A new 7" Panelview HMI will be mounted on the panel, providing basic flow process graphics and control screens. Surface Pro Integration A Microsoft Surface Pro 7 will be installed in the truck. It will run ModbusScope (or equivalent software) for data monitoring and logging. At the end of each oil delivery: A CSV file will be generated from the logged data. The CSV file will include: Dispatch quantities from each flow meter. The final load cell weight. The file will be automatically emailed to both the client and the supplier. Optional: Ability to print the dispatch summary on-site. Remote Access The system must allow secure remote access for: Program updates Troubleshooting Data retrieval The PLC and HMI will be connected to the Surface Pro via an Ethernet switch. Remote access can be implemented using VPN, TeamViewer, or equivalent solution. Scope of Work PLC Programming Develop ladder logic using Rockwell workbench. Control sequences for: Oil dispensing from 4 flow meters. Used oil collection. Pump and valve control. Load cell weight confirmation. Safety interlocks and alarms. HMI Development Design and program using Factory Talk View. Create graphical process pages, including: Tank levels Flow meter readings Pump/valve status Start/stop controls Alarm display Data Logging & Email Automation Integrate ModbusScope (or alternative solution) on Surface Pro. Configure automatic CSV generation after each delivery. Develop an email sending function (with CSV attached) to: Client Supplier Remote Access Setup Implement a reliable remote connection for PLC and HMI (via Surface Pro). Provide a secure method for program updates and troubleshooting. Deliverables Complete PLC program with documentation. Complete HMI project file with all graphics and tags. Email and CSV automation script or configuration. Remote access configuration guide. Proposal Requirements Quote as: Lump sum for the entire project, OR Hourly rate, OR Breakdown by task (PLC, HMI, Remote Access, Email Automation). Provide: Estimated timeline for each deliverable. Any additional hardware/software recommendations. Optional Experience with AB PLCs and HMIs is preferred. Experience with Modbus communication and automation reporting systems. Ability to support remotely during commissioning phase. High-Level Scope of Work for Inovance PLC & HMI Project Control System Supply & Setup Provide an Inovance AB PLC and HMI-based control panel designed for [application: oil filtration/truck system]. (All hardware will be available by the client, setup and ready to remote program using team viewer) Configure communication using Modbus RTU for data exchange between devices. Integrate touchscreen functionality to display real-time data (e.g., pressures, temperatures, flow rates) and allow operator interaction. Automation Logic & Control Develop and implement PLC logic to: Start/stop pumps and filtration units. Manage operational sequences. Include oil line blowout routine for cleaning and system safety. Include safety interlocks, alarms, and emergency stop conditions. Remote Access & Monitoring Configure the HMI and PLC for remote access using TeamViewer or other secure remote access software on a Microsoft Surface Pro 7 (Windows-based). Allow remote diagnostics, programming, and updates. Data Logging & Reporting Configure the system to log operational data (e.g., run hours, oil volume each batch, time) to CSV files. Implement an automated process to email at the command of a easy to use interface on the PC, reports in text or CSV format. A email account will be provided for all mails to be CCd to. Commissioning & Local Support All equipment will be provided, preconfigured, and shipped ready for integration. Commissioning will be carried out remotely using remote access tools. A local licensed electrician will be assigned to perform on-site electrical work and follow remote instructions during commissioning. Documentation & Training Redline markup of electrical drawings and PDF of ladder logic program . Provide remote training for operators and maintenance staff.
