Engineering notes

CIP is one of the largest controllable cost centres in a food or beverage plant. This article covers the four areas where CIP automation investment pays back: cycle optimisation for trade waste and chemical cost, digital audit records, queueing for equipment availability, and coverage verification to prevent silent failures.

A practical Ignition SCADA guide for Australian food and beverage manufacturers, written from an integrator's delivery experience: when Ignition is and is not the right fit, Perspective vs Vision, architecture, CIP and batch, OT security, and buying and supporting Ignition in Australia.

How to plan a legacy PLC migration on a live Australian plant without losing production: when to start, how to scope the outage window, and how to stage the cutover.

OEE is useful but routinely over-trusted. This guide covers what OEE leaves out by design, where it distorts on multi-SKU Australian food and beverage lines, why cross-line comparisons fail, and the one limitation that is actually fixable: the signal layer between the machine and the dashboard.

How a controls engineer reads a P&ID and its ISA-5.1 symbology, then derives equipment modules, sequences, interlocks and control loops from the drawing plus a short conversation about how the plant runs.

How to tune PID loops on food and dairy plant: why most flow, pressure and level loops run PI, why slow thermal loops justify full PID with anti-windup, and a structured lambda method over trial and error.

Water hammer cracks seals, fatigues instruments and damages hygienic lines. This article covers the control-system levers that prevent it: VFD ramps, valve-closure profiling, pump-valve sequencing and pump-type protection.
