Extract data from any
SECS/GEM equipment.
Without touching a thing.
SmartPassThrough (SPT) taps the SECS/HSMS line between your Host and your equipment — intercepting, analyzing and routing data to any destination, with zero impact on your automation or MES.
No software modification
Your equipment runs exactly as before. SPT is invisible to it.
No Host disruption
SECS/HSMS communication is 100% transparent and uninterrupted.
Any output destination
Route data to FDC, SPC, E84, custom automation via REST/TCP/MQTT.
A passive tap on your SECS/GEM line.
SmartPassThrough is placed between a SECS/GEM device and its Host. It intercepts every SECS message flowing in both directions — analyzes it, understands it, reacts to it — then forwards it unchanged to the other side.
The Host and the equipment see each other exactly as before. SPT is completely invisible to both. But SPT now has full visibility into all the data exchanged — events, alarms, process parameters, loadport status — and can route it to any downstream system.
It can also insert custom SECS messages into the line without interfering with the main communication channel — enabling automation extensions, synchronized reactions to equipment events, or custom equipment-to-equipment communication.
Important: SmartPassThrough requires engineering work per tool type to map the relevant SECS messages. It is not a plug-and-play product — Focussia engineers assess your tool’s SECS vocabulary and configure the tap accordingly. Contact us to evaluate your use case →
How the tap works
Every SECS message flowing between HOST and TOOL passes through SPT. Both directions, in real time.
SPT decodes the SECS/HSMS messages — understands message type, stream, function, and payload content.
The message is forwarded as-is to the intended recipient. The communication channel is 100% preserved.
Events, alarms, parameters — extracted and sent to FDC, SPC, E84, REST APIs, custom automation.
What SmartPassThrough enables
From real-time data collection to automation extension — SPT unlocks new capabilities from equipment you already have.
Data Collection
Real-Time SPC / FDC Data Extraction
Capture process parameters, recipe data and equipment events in real time from any SECS/GEM tool — without modifying MES integration or equipment software. Feed directly into your SPC or FDC systems.
Process Control
Run2Run Control
Intercept end-of-lot events and trigger immediate recipe adjustments on the next run. SPT acts as the synchronization layer between equipment outputs and process control decisions — no Host reprogramming.
Automation
Automation Extension
React to equipment events (alarms, state changes, lot completion) to trigger external actions — robot moves, E84 loadport signals, HMI alerts — without touching the existing automation stack.
Data Collection
Sensors & Peripheral Integration
Correlate SECS equipment events with external sensor readings (temperature, vibration, gas flow). SPT provides the synchronization layer between tool events and peripheral data streams.
E84 / AMHS
E84 Loadport Status from SECS
For FABs upgrading legacy tools: SPT extracts the loadport status signals from SECS messages and feeds them into SmartBoxE84 — enabling AMHS E84 compliance without any tool controller modification.
Synchronization
Equipment-to-Equipment Synchronization
React to events on one tool and trigger actions on another — across tool types and vendors. SPT can inject custom SECS messages or REST calls to build multi-tool synchronized workflows.
From installation to live data extraction.
SPT deployment follows a structured 4-step process. Focussia engineers lead the SECS message mapping — the most critical and tool-specific step. Once done, deployment to additional tools of the same type is fast.
SECS Message Mapping
Focussia engineers analyze the target equipment’s SECS/GEM vocabulary — identifying the exact messages, streams and functions that carry the data you need. This is done per tool type, not per unit.
SPT Configuration & Installation
SPT is installed on a Linux platform (dedicated device or VM) and positioned between the Host and the tool on the network. The tap is configured with the message map from step 1.
Live Capture & Data Validation
SPT goes live on the SECS line. We validate that all targeted messages are correctly intercepted, decoded and routed — while confirming zero impact on Host/Tool communication.
Rollout to Additional Tools
With a validated per-tool-type playbook, deployment to the next unit of the same tool family takes hours. One configuration, replicated across your fleet — with Focussia support throughout.
SPT Output Destinations
FDC / SPC Systems
REST API, TCP socket or MQTT — push extracted data directly to your Fault Detection or Statistical Process Control system.
Automation / Robots
Trigger PLC signals, robot actions or MES events from SECS messages — without modifying the main automation.
SmartBoxE84 / AMHS
Feed loadport status directly into SmartBoxE84 from SECS signals — enabling E84 on legacy tools with no controller change.
Databases / Data Lakes
Log all extracted SECS events into SQL, time-series or cloud databases for post-process analysis and traceability.
Technical Specifications
SmartPassThrough & SmartGem — stronger together.
SmartPassThrough is often deployed alongside SmartGem, Focussia’s SECS/GEM platform. While SmartGem manages the full SECS/GEM Host interface for an equipment, SPT adds a non-intrusive data layer on top — enabling data extraction without changing the main SmartGem configuration.
They can also be used independently: SPT on legacy tools with existing Host automation, SmartGem for new OEM equipment without any Host connection.
SmartPassThrough
Passive tap on existing SECS line. No Host, no equipment change. Data extraction only.
Non-intrusive
SmartGem
Full SECS/GEM Host interface. New equipment connection. Active GEM communication.
Active integration
Combined: SPT + SmartGem
Full Host communication managed by SmartGem + additional non-intrusive data channel via SPT. Best of both worlds.
Is SmartPassThrough right for your use case?
SPT requires a use-case assessment: tell us your tool type, the data you want to extract and your target output. Our engineers will evaluate feasibility and propose a configuration. No commitment.
