Electrical drawings, PLC automation, ABB drives and SICK safety for grain handling, hay presses, pellet mills and batching plants — designed by hands-on electricians, for electricians.
Control system drawings — by electricians, for electricians
Our drawings are made by hands-on electricians who build, wire and commission these plants themselves. They're laid out the way work is done on site, so your electrical team can quote, build and fault-find from them with confidence.

Why electricians like them
Drawn by people who've pulled the cable
Wire numbers and I/O match the PLC program
Drawings, program and HMI all line up, so faults are found fast
Extensive experience designing control rooms for agricultural sites, where dust, heat and long cable runs are part of the job.
Cable routing & cooling
Segregated power, control and network cabling, planned from the start, with room and panel cooling sized for drives and hot-climate summers.
Dust prevention
Sealing and filtration to keep grain and feed dust out of electronics.
Machine Safety
SICK Flexi Soft — safety designed in, not bolted on
Flexi Soft is SICK's software-programmable, modular safety controller. Every E-stop, guard switch and safety device on the plant is wired into one safety CPU, with the safety logic configured, tested and documented in SICK's Flexi Soft Designer software.

What it gives your plant
One safety system for the whole machine. E-stops, guard interlocks, light curtains and drive STO all handled by one safety CPU.
Grows with the plant. Modular, expandable from 12 to 144 safety inputs and outputs.
Fast replacement. The whole configuration is held in a removable system plug, so a replacement CPU is back running quickly.
Visible to the operators. Ethernet gateways (EtherNet/IP, Modbus TCP) send status and diagnostics to the BRX PLC and HMI, so operators see exactly which E-stop or gate tripped.
Documented and verifiable. Logic is configured and reported from Flexi Soft Designer for validation records.

Built around AS/NZS 4024.1 — Safety of Machinery
The AS/NZS 4024.1 series is Australia's framework for designing and operating safe machinery. Its 26 parts adopt the international ISO and IEC machinery safety standards, with changes to suit Australian practice. Our safety designs follow three of its key parts:
AS/NZS 4024.1201
Risk assessment and risk reduction (ISO 12100) — identify hazards first.
AS/NZS 4024.1503
Safety-related parts of control systems (ISO 13849-1) — the required Performance Level for each function.
AS/NZS 4024.1602
Interlocking devices on guards — selection and design of gate switches.
Ratings shown are for the Flexi Soft controller. The level each safety function achieves depends on the complete design, devices and validation.
ABB Preferred Partner
ABB ACS drives — control, efficiency & safety
We standardise on ABB's ACS variable speed drive range: the ACS580 general purpose drive (0.75–500 kW) for pumps, fans, conveyors and mills, and the ACS880 industrial drive where advanced drive-based safety is needed.
Motor Control
Accurate speed and torque control, even as load changes
Soft, controlled starts and stops reduce mechanical wear
Runs induction and high-efficiency permanent magnet motors
Built-in EMC filter and choke for cleaner supply
ABB Drive Composer PC tool for set-up, monitoring and process tuning
Power Saving
≈ 50% lessPower drawn by a fan or pump run 20% slower (affinity laws)
Energy optimiser gives maximum torque per amp, cutting energy drawn from the supply
Built-in energy efficiency information shows energy used and saved
Run to demand instead of full speed
Advanced Safety
Safe Torque Off (STO) built in, rated SIL 3 / PL e (TÜV certified)
STO wired to SICK Flexi Soft for a high standard of emergency stop
On ACS880, the plug-in safety module adds Safe Stop 1, Safely-Limited Speed, Safe Maximum Speed, Safe Brake Control and Prevention of Unexpected Start-up
Safe speed monitoring without an encoder
Fieldbus control from the PLC
Our drives are controlled over a network, not dozens of control wires. Modbus RTU is built in, and plug-in adapters add Modbus TCP, EtherNet/IP or PROFINET.
Start/stop and speed set from the BRX PLC
Current, power, faults and energy sent back to the HMI
Less wiring, faster fault finding
ABB drive panel, networked to the PLC
PLC Automation
BRX PLC — advanced programming, open communication
The AutomationDirect BRX, running Do-more technology, is a compact PLC built for both simple and demanding applications. We program it in-house and pair it with Weintek touchscreen HMIs that operators find easy to use.
Advanced programming
Do-more Designer ladder with strong maths, string and data handling for complex sequences and recipes.
100+ PID loops
Process control for temperature, pressure, flow and level, with built-in PID tuning views.
Tested before site
The built-in simulator lets us test the program in the office before it reaches your plant.
Data logging
Production and event data logged to the on-board microSD card, plus trend views for troubleshooting.
Open Ethernet
Modbus TCP, EtherNet/IP, a built-in web server, REST API and email alerts on the same port.
Scales with the plant
Expansion and Ethernet remote I/O take a system past 4,000 discrete I/O points.
