A global flavours and fragrances manufacturer engaged Mobile Automation for a large automation and systems-integration project at its Dandenong South plant — bringing blenders, clean-in-place (CIP), an automated storage and retrieval system (ASRS) and scrubbers together under a single SCADA, in a hazardous-area environment.
One control-module standard across the plant
The software standard was settled with the engineering team before the bulk of the code was written.
- Siemens control-module libraries assessed side by side and one standard adopted
- A single Ignition faceplate concept designed and tested for reuse across the project
- UDT definitions for unit control and equipment-module control matched to the faceplates
- Modular embedded views, a navigation menu and version control in place from the start
Schematics tying four MCCs together
Design documentation covered the CIP, scrubber, blender and powders MCCs.
- Schematics and parts lists issued for approval and revised as specifications were confirmed
- Scrubber VSD options, HMI specifications and the powders MCC supply settled at drawing stage
- P&ID used to drive SCADA screen structure
- Recipe handling, gateway-to-Edge communications and Danfoss drive configurations decided before programming
Cabinets engineered for an outdoor installation
The MCCs live outside, so the enclosures were built for weather.
- Rainhoods designed for the CIP MCC and scrubber enclosures
- HMI sun shield drawn from site measurements, welding requirements specified to the fabricator
- Mounting and gland plates made in our workshop, earthing designed and PVC duct set out to suit
- Every panel wired, loomed, labelled and point-to-point tested before transport
The results
- Blenders, CIP, ASRS and scrubbers running under a single Ignition SCADA
- Code proven against test gear and Ignition faceplates on the bench, with PLC and SCADA UDTs verified against each other
- Purpose-built screens used to check CIP devices and instruments during commissioning
- AS-i testing completed in the field with cable tags reconciled against valve numbers
- Sacchi interface programmed and proven against its own test suite
- ANZEx/IECEx certification compiled for the hazardous-area equipment
