Module - Host Agent

Use-cases

Advanced Identity & Operator Security

The modern plant floor requires frictionless, rigid authentication without relying on manual password entry.

Use Case

The Challenge

The Host-Agent Solution

Business Value / ROI

Sessionless RFID / NFC Login

Browsers require an active, focused text field to read RFID badges, leading to failed scans and frustrated operators.

Agent captures raw badge data from local COM/USB readers in the background—even if Perspective isn't running or focused.

Frictionless Security: Lightning-fast operator switching, eliminating lost time and bypassed security protocols.

21 CFR Part 11 Biometrics

Pharmaceutical and F&B industries require rigid e-signatures (fingerprint/palm) that browsers cannot natively process.

Natively interfaces with biometric device drivers on the client OS, sending encrypted authentication tokens to the Gateway.

Compliance: Ensures audit-proof compliance for regulated industries without clunky third-party apps.


File System Automation & Legacy Machine Bridging

Connecting "unconnectable" legacy equipment that relies on local file generation.

Use Case

The Challenge

The Host-Agent Solution

Business Value / ROI

Legacy LIMS & Certificate Retrieval

Older machines (e.g., LIMS, CNCs) dump PDF certificates or CSVs to a local folder. IT blocks SMB network shares due to security risks.

Agent "watches" specific local directories, instantly picking up new files, parsing them, and transmitting them securely to the Ignition Gateway.

IT-Friendly Integration: Eliminates ransomware risks associated with network shares while digitizing legacy machine data.

Automated Recipe Distribution

Older PLCs/HMIs can only read recipe files from a local C: drive.

Gateway pushes recipe files through the Agent directly to the target machine's local folder.

Centralized Control: Allows unified recipe management in Ignition, even for antiquated production lines.


Bidirectional Peripheral Integration

Industrial environments rely on raw hardware that requires continuous, two-way communication.

Use Case

The Challenge

The Host-Agent Solution

Business Value / ROI

Smart RS232/USB Scanners

Standard browser barcode scanning only acts as a keyboard. It cannot handle ACK/NACK signals or bidirectional handshakes.

Establishes persistent serial connections. Agent handles bidirectional logic, confirming successful reads directly with the scanner hardware.

Zero-Defect Scanning: Prevents mis-scans and data loss, crucial for strict traceability environments.

Live Measurement Tools & Scales

Operators manually type in weights from bench scales or dimensions from digital calipers, causing typos.

Streams live COM-port data directly from scales/calipers into Ignition tags in real-time.

Data Integrity: Eliminates human error in Quality Assurance data entry.

Direct-to-Device Printing

Managing network print servers for hundreds of Zebra/EPL label printers is an IT nightmare.

Sends raw ZPL strings via USB/Serial directly to the locally attached printer.

High-Reliability Printing: Prints instantly without network latency or complex OS driver setups.

OS-Level Control & Edge Telemetry

Unifying the operator experience and proactively managing client hardware.

The Host-Agent Solution

Business Value / ROI

3rd-Party App Orchestration

Operators have to juggle Perspective and native OS apps (like a proprietary camera viewer or 3D CAD software).

Ignition triggers the Agent to launch, maximize, or close local applications based on Gateway events.

Unified Workspace: Operators stay focused on the Ignition screen; external apps only appear when strictly needed.

Client Health & Kiosk Management

Terminals crash or run out of disk space silently, causing unexpected downtime.

Agent publishes client CPU, RAM, disk space, and network status to the Gateway. Allows remote reboot/sleep commands.

Proactive Maintenance: IT/OT can predict and resolve terminal failures before they stop production.

Dual-NIC Edge Bridging

A terminal is connected to both the corporate network (Gateway access) and an isolated machine network (PLCs/Cameras).

Agent polls local devices on the isolated network and passes the data up to the central Gateway.

Network Architecture: Avoids expensive network routing redesigns while securely bridging data gaps.

Technical Advantages

  • Bypasses the Browser Sandbox securely: Extends Perspective's reach without compromising the security model of modern web browsers.

  • No SMB/Shared Folders Required: Eliminates a major vector for ransomware on the plant floor. All communication is routed securely over the Ignition Gateway connection (HTTP/HTTPS/WSS).

  • Tag-Based Architecture: The host-agent communicates seamlessly with Ignition tags. To the Perspective developer, interacting with a local RS232 scanner or the local C: drive feels exactly like reading/writing standard OPC tags.

  • Resilience & Offline Buffering: If the connection to the Gateway drops, the agent can buffer local file events and hardware scans, pushing them to the Gateway once the connection is restored.
