RockPlus GEMLink

SECS/GEM Equipment Integration Platform

Unified equipment communication: turn one-off device integration into a reusable capability

RockPlus GEMLink is an equipment communication and automation foundation platform built by Hegong Software for the semiconductor, electronics and photovoltaic industries. Through standardized SECS/GEM communication it connects production equipment with EAP / MES / Host systems, uniformly handling key interactions such as equipment status, events, alarms, remote commands, recipes and communication logs, reducing the complexity of integrating multi-brand equipment and scaling over time.

BUSINESS CHALLENGES

Equipment integration is more than just reading data out

What really limits production line automation is the long-term complexity of multi-brand equipment integration, business closed loops and replicating to new lines.

01

Divergent Equipment Interfaces

Vendors differ in communication methods, data variables, event definitions and control capabilities, forcing upper-layer systems to adapt repeatedly.

02

Hard to Replicate Integration

When new equipment or new production lines are added, developing each device from scratch keeps increasing project cycles and maintenance costs.

03

Automation Closed Loops

Production requires more than data collection: complete business interactions such as Event, Alarm, Remote Command and Recipe must be closed-loop.

04

High On-Site Integration Cost

Real-equipment testing windows are limited; resolving interface issues on site lengthens go-live schedules and raises implementation risk.

Unified Equipment Communication Layer

Converging multi-brand equipment differences into one standard platform

RockPlus GEMLink sits between production equipment and EAP / MES / Host systems. Downward it standardizes the communication interfaces, data variables, events and control capabilities of different equipment; upward it provides a unified communication foundation, so business systems no longer need to adapt to every device individually.

Core goals: unified connection, unified messaging, unified events and unified control — building a reusable foundation for equipment automation and new production line replication.

FAQ

What is SECS/GEM? How do SECS-II, GEM and HSMS relate?

SECS/GEM is the standard communication framework commonly used between semiconductor equipment and upper-level systems such as Host and EAP. SEMI E5 (SECS-II) defines messages and data structures, SEMI E30 (GEM) defines the equipment behavior model, and SEMI E37 (HSMS) provides TCP/IP-based high-speed message transport; together they form the common foundation of equipment automation communication.

How does SECS/GEM software connect equipment with EAP, MES or Host systems?

SECS/GEM software sits between production equipment and EAP, MES and Host systems, handling equipment connection, message exchange, state, events, alarms, remote commands and recipes. RockPlus GEMLink hides the differences between equipment brands through a unified SECS/GEM communication layer, letting upper-level systems connect to many kinds of production equipment in a standard way.

Can equipment without a native SECS/GEM interface be connected through a gateway?

It can be assessed based on what the equipment already exposes. For equipment without a native SECS/GEM interface, capabilities can be obtained through OPC DA, OPC UA, Web Service, API or RESTful interfaces and then standardized by RockPlus GEMLink, presenting a unified SECS/GEM communication capability upward; the specific solution depends on the equipment's actual interfaces.

What equipment data can SECS/GEM software collect and what functions can it control?

Beyond equipment data collection, SECS/GEM also handles equipment state, variables, events, alarms, remote commands and recipe management. RockPlus GEMLink keeps communication and exception logs in one place, enabling EAP, MES or Host systems to build data collection, monitoring and automatic control processes around equipment.

What is the difference between SECS/GEM software, a SECS/GEM communication platform and an EAP system?

SECS/GEM software or a communication platform mainly solves equipment communication and standardized connectivity; EAP focuses more on equipment automation workflows, equipment coordination and production control. RockPlus GEMLink is positioned as the SECS/GEM communication foundation layer between equipment and EAP, MES or Host, so upper-level business systems do not have to adapt to each equipment brand's communication interface separately.

When adding new brands of semiconductor equipment, how can the SECS/GEM integration effort be reduced?

If every new equipment type requires its own SECS/GEM interface development, maintenance costs grow with the number of machines. RockPlus GEMLink reuses verified communication capabilities, equipment drivers and configuration logic, and only adapts the variables, events and interface differences of the new equipment, gradually turning equipment connection from one-off projects into repeatable platform capability.
