System Integration

PLC, SCADA & DCS Integration

SentinelAI connects directly to your existing automation infrastructure. No proprietary controllers, no rip-and-replace. Plug into the safety circuit of any industrial control system.

Integration Methods

Four ways to connect

Universal — Recommended

Dry Contact Relay Output

Hardware relay — works with every PLC ever made

SentinelAI provides a normally-closed (NC) dry contact relay output. Wire it directly in series with your existing E-STOP circuit. When a human is detected, the relay opens — triggering an emergency stop exactly like a physical mushroom button. No software, no protocol, no compatibility issues.

Industrial Ethernet

Modbus TCP / EtherNet-IP

MODBUS TCP · EtherNet/IP

SentinelAI exposes a Modbus TCP server. The PLC reads detection status, zone states, and alarm codes as register values in real time. Full bidirectional communication — read zone status, write zone enable/disable from the PLC.

Siemens

PROFINET / PROFIBUS

PROFINET IO · PROFIBUS DP

SentinelAI supports PROFINET IO device mode for direct integration with Siemens SIMATIC S7-300/400/1200/1500 series PLCs. The system appears as a PROFINET IO device in TIA Portal. GSDML file provided.

SCADA / DCS

OPC-UA Server

OPC-UA · REST API

SentinelAI runs an embedded OPC-UA server. All zone states, detection events, and system health metrics are available as OPC-UA nodes — subscribable by any SCADA client (WinCC, Wonderware, Ignition). A REST API is also available for custom integrations.
