One Flow, Handled Easily

On the plant floor, indicators, PLC, and SCADA run each stage reliably — OMAC ERP connects the same flow for the office and management team.

Inward material — no guesswork on quantity

Weighment indicators capture first and second vehicle weights so net received material is automatic. The same station supports invoice checks against purchase orders before warehouse unload — less manual calculation and fewer entry errors.

Formulation — office to floor, one recipe

When the office sets the production ration for a sales order, that formula lives on SCADA/HMI. Production loads hoppers to match, and the supervisor starts the batch from the same data — no retyping ratios on the plant floor.

Automated line — PLC dose, grind, mix

On fully automated plants, PLC runs each batch: ingredients hit target weight on in-line weighment, then motor drivers run the grinder and mixer before discharge to the feed hopper. Operators supervise; the sequence does not depend on paper slips.

Dispatch — confirmed load weight

Outward vehicles use the same weighment setup — in-weight and out-weight give the customer delivery quantity without a separate manual tally.

Batch limits — full orders without overload

Each machine has a capacity (for example 1 ton per batch). SCADA and PLC scale the formula to that size and repeat batches until the sales order is complete — safe for equipment and easy for supervisors to track progress.

Automated & Manual Plants

Feedmills often run both styles — OMAC supplies full PLC automation where the line is automatic, and semi-automation where labour still loads, grinds, and mixes by hand.

Automated production

Material loading, in-line weighment dosing, grinder, and mixer run under PLC and motor drivers. The supervisor enters the formula on SCADA/HMI and starts the batch; the machine sequence handles the rest.

PLC SCADA VFD
Manual production

Labour loads each ingredient onto the machine by weight using a visual weighment indicator. Grinding and mixing are also done by labour — there is no automatic transfer between machines.

Guided Weighing for Manual Lines

Manual plants still load, grind, and mix by hand — but dosing no longer depends on paper slips. An SBC production display beside the scale walks labour through each ingredient with live weight from the indicator.

Before
  • A4 formula sheets from the office
  • Cumulative weights tallied by hand
  • Wrong ingredient or short load caught late
  • Batch data re-entered in the office
With OMAC semi-auto
  • Formula selected on the floor display
  • SBC calculates target from live indicator
  • Image + audio prompt per material step
  • Actual weights logged for ERP traceability
  • Step-by-step guidance — current material, target weight, and progress bar update as labour loads
  • No retyping recipes — office formulation syncs to the production HMI; supervisor picks the batch and starts
  • Grind and mix stay manual — semi-automation covers dosing accuracy; existing labour workflow for downstream steps is unchanged

Built for Feedmill Management

OMAC developed an ERP for feedmills so purchase, weighment, warehouse, formulation, production batches, and dispatch stay in one system — not scattered across registers, spreadsheets, and phone calls.

  • Purchase & inward — raise POs in ERP; weighment net weights post against the order so management sees what was actually received
  • Stock & warehouse — inventory updates from inward and batch consumption; owners know what is in silos without walking the plant
  • Sales & formulation — customer orders and production rations created once; production and SCADA use the same formula
  • Batch tracking — automated PLC batches and manual semi-auto batches both link to sales orders; repeat until the order is complete
  • Manual line data — semi-automation logs what labour actually weighed and produced; ERP picks it up without re-entry in the office
  • Dispatch & billing — outward in/out weights recorded against the delivery; fewer disputes on quantity shipped
  • Reports for management — material usage, production output, pending orders, and dispatch history for daily decisions and month-end review
