Tyre manufacturing runs on precision, repeatable machine cycles — building drums, curing presses, and conveyor transfer lines that must hit the same sequence, thousands of times a shift, without drift. That is why tyre plants specify industrial-grade controllers rather than relay panels. Below is the full list of Siemens PLCs, VFDs, HMI panels, and SCADA software that tyre plants specify, along with why each product fits its station on the line.
Applications in Tyre Industry
- Tyre building machine control — drum indexing, ply and belt splicing, and stitching sequences that must repeat exactly for every tyre in a batch.
- Curing press temperature & pressure — closed-loop control of mold temperature, steam/nitrogen pressure, and cure time across banks of presses running different tyre sizes in parallel.
- Mixing mill & downstream conveyors — speed-synchronized conveyors moving rubber compound from the Banbury mixer through calendering and extrusion.
- Barcode tracking & reject logic — scanning green tyres and cured tyres at each station to track batch data and automatically divert rejects.
- Warehouse conveyor systems — finished-goods sortation and transfer conveyors linking curing to the warehouse or dispatch bay.
- Recipe management — storing and recalling machine parameters per tyre size/SKU so changeover between products does not require manual re-entry.
- Field level: proximity sensors, encoders, pressure and temperature transducers on drums, presses, and conveyors feed real-time data to the controller.
- Control level: a SIMATIC S7-1200 G2 or S7-1200 PLC runs the drum indexing, curing sequence, and recipe logic for each machine; larger plants standardize on the S7-1500 where a single controller supervises multiple stations.
- Drive level: SINAMICS G120X VFDs run main conveyors and mixers, while SINAMICS V20 drives handle smaller rollers and auxiliary motors.
- Local HMI: a KTP1200 Basic Panel or compact KTP700 Basic Panel sits at each machine station for recipe selection, fault display, and batch counting; a TP1200 Comfort Panel is used where trending or multi-recipe screens are needed.
- Supervisory level: WinCC RT 512 SCADA aggregates data from building machines and curing presses for shift-wise production tracking, downtime analysis, and batch traceability.
- Engineering layer: TIA Portal is used to program the PLC, configure HMI screens, and commission VFD parameters from one engineering environment, which shortens changeover engineering when a new tyre size is added to the line.

PLC VFD HMI SCADA
Per machine (single building machine or curing press): S7-1200 G2 + G120X/V20 + KTP1200.
Plant-wide with MES/traceability (multiple building machines, curing bank, warehouse conveyors): S7-1500 + WinCC SCADA tying all stations together.
Why These Products in Tyre Industry?
Tyre building and curing rely on exact timing rather than raw processing power, which is why the S7-1200 G2 and S7-1200 PLCs are the standard choice for drum indexing, ply-splicing sequences, and curing press temperature/pressure loops — they hold tight scan-cycle repeatability and store multiple recipes for fast size changeover. Where one controller needs to coordinate several stations or a high I/O count across a curing bank, the S7-1500 gives the extra processing headroom and memory.
On the drive side, the SINAMICS G120X runs main conveyors and mixing-mill drives where speed needs to track line rate smoothly, while the compact SINAMICS V20 is a cost-effective fit for small rollers, feeders, and auxiliary motors that do not need advanced process functions.
Each machine station typically gets its own local HMI — the KTP1200 Basic Panel or the smaller KTP700 Basic Panel — for operators to select recipes, view faults, and track batch counts without walking to a control room. Where a station needs on-screen trending or multi-page recipe navigation, plants step up to the TP1200 Comfort Panel.
Once a plant runs multiple building machines and curing presses together, WinCC RT 512 SCADA ties them into one view for shift production counts, downtime reasons, and reject tracking — most single-line or single-plant tyre operations fit comfortably within its tag limit. TIA Portal is the common engineering software across all of this, since PLC logic, HMI screens, and VFD parameters can be configured and diagnosed from a single project.
Common Mistakes to Avoid
- Under-speccing the PLC memory for recipes: tyre plants running many SKUs need enough recipe/data block storage in the PLC — check this before finalizing the controller, not after commissioning.
- Using fixed-speed motors on mixing mill conveyors: without a VFD, speed cannot be matched to upstream mixer output, which causes compound buildup or gaps on the line.
- Skipping local HMI for "cost saving": operators need machine-level fault and recipe display even where a central SCADA exists — relying on the control room alone slows down changeovers and troubleshooting.
- Mixing HMI families across stations: standardizing on one HMI family (e.g. all KTP1200) simplifies spares stocking and operator training compared to mixing multiple panel types across the plant.
Frequently Asked Questions
Which PLC for tyre conveyor lines?
S7-1200 G2 or S7-1200 — most common on tyre building and transfer conveyors.
Which VFD for tyre curing and conveyors?
G120X for main lines. V20 for small rollers and auxiliary drives.
Which HMI on tyre machines?
KTP1200 Basic — recipe, fault display, batch counter at each station.
Why do tyre building machines need a PLC instead of relay logic?
A PLC handles drum indexing, ply-splicing timing, and recipe changeover in software, which relay logic cannot do reliably at the speed and repeatability tyre building requires, and it allows fast recipe changes between tyre sizes without rewiring.
Why use a VFD on tyre plant conveyors instead of fixed-speed motors?
A VFD lets conveyor and mixer speed be matched to line rate, reduces mechanical shock on gearboxes during start/stop, and cuts energy consumption compared to running motors at fixed speed with a soft starter or DOL contactor.
Do tyre plants need SCADA on every line?
Not always. Individual machines can run standalone on a local HMI, but most tyre plants add WinCC RT 512 SCADA once they need production tracking, downtime reporting, or batch traceability across curing presses and building machines.
