Machine connectivity, edge gateways and edge-to-cloud, data acquisition, MES integration, IIoT security and brownfield retrofit: the data layer of Industrie 4.0, with the test and programming tools to prove every hop.
Underneath the dashboards, Industrie 4.0 is a connectivity and data problem. Each card lights the point in the plant where that work sits, from the machine on the floor to the MES and the cloud.
Getting data off the machine is the first problem of Industrie 4.0. GSAS implements the protocol layer so PLCs, drives, sensors and meters speak to the gateway reliably.
SEGGER emModbus · emNet · Arm
The edge is where raw machine data becomes useful. Gateway firmware filters, buffers and pre-processes at the edge and sends only what matters, cutting bandwidth and latency.
AutoPi · SEGGER emNet
You cannot optimise what you do not measure. GSAS captures machine and process data, time-stamps it and feeds live dashboards for OEE, energy and condition monitoring.
GW Instek DAQ-9600
On the factory floor, machine data has to reach the MES. GSAS wires production programmers and stations into it, so serialisation, traceability and pass/fail flow straight through.
ProMik FlashTask Pro · XTL-i
A connected machine is an attack surface. GSAS secures the data path and shifts security left into the firmware itself.
SEGGER emSSL · Perforce Klocwork
Many plants run machines that were never built to be connected. The value is in connecting machines that already run, without re-engineering the line.
Gateway and DAQ, sized to the machine
One reading’s path from the machine to the dashboard, hop by hop, and the three stages GSAS works through to build it. Hover a stage to see its hops.
01
Brownfield machines joined without replacing them
02
Security built into the firmware, not added at the network edge
03
One data layer from the sensor to the dashboard

01
Machines that already run
Non-intrusive data capture and protocol-bridging gateways on the machines you have, so older equipment joins the same Industrie 4.0 data layer as the new, without re-engineering the line.
02
Connectivity inside the product
The protocol stack and gateway firmware inside your controller: Modbus, OPC-UA, MQTT and CAN-FD on embedded targets, TLS on the uplink, and static analysis on the firmware before it ships.
03
Programming and test into the MES
Production programmers and test stations wired into the MES over OPC-UA and REST, so serialisation, traceability and pass/fail flow straight into your Industrie 4.0 data systems.
Tell us the machines, the protocols and where the data needs to go. GSAS scopes the connectivity, edge and security layers, validates them with real test and programming tools, and supports them across Bengaluru, Hyderabad, Chennai, Pune, Mumbai and Delhi NCR.
The data layer of Industrie 4.0: machine connectivity and protocols, edge gateway firmware, machine data acquisition, MES integration, IIoT security and brownfield retrofit, from the sensor on the machine to the dashboard, with the test and programming tools to validate every hop.
Modbus RTU, ASCII and TCP (SEGGER emModbus), OPC-UA, MQTT (over SEGGER emNet), and CAN and CAN-FD.
Yes. Brownfield retrofit is a core part of the work: non-intrusive data capture and protocol-bridging gateways bring legacy machines into the same data layer, and a multi-channel DAQ such as the GW Instek DAQ-9600 captures signals directly where a machine exposes no data at all.
TLS transport with SEGGER emSSL (TLS 1.3), integrated with emNet, secure boot and an IEC 62443-aligned architecture, with Klocwork static analysis in a DevSecOps pipeline so the gateway firmware itself is checked on every change.
Yes. GSAS integrates production programming into the MES over OPC-UA and REST. ProMik FlashTask Pro offers a REST API and built-in SQL traceability, and the XTL-i inline system connects over OPC-UA, REST and OPCON/ITAC.
Engineering is led from Bengaluru, with GSAS offices across India including Hyderabad, Chennai, Pune, Mumbai and Delhi NCR, so plant visits and support run in the same time zone as the line.

A fleet manager sees a row in a portal; an engineer sees parameter groups on a CAN bus. Between them sit a gateway that selects, samples, derives and timestamps, and a standard that governs only the last hop. How to validate the whole path against the bus.
How Indian industrial gateway OEMs use SEGGER emSSH, a commercial SSH-2 server library, for secure remote management, SCP log retrieval, and fleet automation of deployed Cortex-M products across Indian solar farms, factories, and transport networks.
