Enable seamless cross-controller automation logic — connect, synchronise, and orchestrate multiple PLCs across your plant floor without middleware overhead or vendor lock-in.
Alphatech's PLC to PLC Control System enables direct data exchange between programmable logic controllers from different vendors and across different production zones. By eliminating centralised middleware, you get lower latency, fewer single points of failure, and simpler commissioning — all while keeping full auditability through our cloud SCADA layer.
Everything you need to connect controllers reliably — pre-configured, tested, and ready to deploy.
Translate data between Modbus, Profinet, EtherNet/IP, OPC-UA, and RS485 without custom code.
Read and write registers, coils, and tags across PLCs in real time with configurable scan rates.
Primary and secondary communication paths with automatic switchover to prevent production stops.
Configure cross-controller interlocks and permissives — safety signals shared between zones instantly.
All P2P data streams are logged and visualised in the CloudSCADA dashboard for trend analysis.
Instant SMS and WhatsApp alerts if any PLC communication link degrades or drops.
Coordinate production sequences across multiple cells, lines, or buildings from one logical layer.
Encrypted communication between all controllers prevents unauthorised access or data injection.
Direct PLC-to-PLC communication removes the need for a dedicated data concentrator at every junction, cutting both hardware cost and latency.
Eliminate intermediate communication servers and OPC concentrators between production zones.
Sub-10 ms data exchange enables tight interlocking between high-speed machines and safety systems.
Mix and match Siemens, Rockwell, Mitsubishi, and Schneider controllers freely — no forced upgrades.
Add new PLCs to the mesh without redesigning existing communication topology or rewiring.
Wherever multiple controllers need to work in concert — across zones, buildings, or sites.
Our automation engineers will design a PLC-to-PLC topology tailored to your production layout and brand mix.
