SECS/GEM Compliance for PLC-based Equipment
NxSphere® GEMBridge (formerly known as SecsToPLC.NET) is a no-code SECS/GEM gateway that connects PLC, Modbus, or SCADA-based machines (via OPC UA) to a factory host without changing any PLC program.
It lets you map equipment tags directly to GEM variables, events, alarms, and commands through a visual configuration interface, then deploys everything as managed Windows services for stable operation.
With built-in OPC tag import, intelligent tag-to-GEM mapping, custom handlers, and one-click SECS/GEM manual generation, GEMBridge gives engineering teams a fast, reliable way to achieve GEM compliance on PLC-controlled tools without custom development. It ensures clean host communication while letting your PLC logic stay exactly as it is.

FAQ
What is NxSphere® GEMBridge and who is it for?
NxSphere® GEMBridge is a no-code SECS/GEM gateway designed for equipment that uses PLCs, Modbus, or SCADA controllers. It enables OEMs and integrators to achieve SECS/GEM host compliance on PLC-controlled tools without writing SECS/GEM driver code or modifying existing PLC programs.
Do I need to change my PLC code to use GEMBridge?
No. GEMBridge connects to your equipment via OPC UA and maps PLC tags to GEM services through a visual configuration interface. Your existing PLC logic stays exactly as it is.
What protocols does NxSphere® GEMBridge support?
GEMBridge connects to equipment via OPC UA, Modbus, and SCADA protocols. On the host side, it communicates using standard SECS/GEM over HSMS (TCP/IP).
How is GEMBridge deployed on the equipment?
GEMBridge deploys as managed Windows Services. The built-in Admin Panel lets you configure, deploy, and monitor all GEMBridge instances from a single dashboard.
Can GEMBridge handle custom fab-specific requirements?
Yes. GEMBridge supports extensible custom handlers that let you implement bespoke messaging workflows beyond standard GEM services, adapting to specific factory host requirements.
Is a free evaluation of NxSphere® GEMBridge available?
Yes. NxSphere® GEMBridge offers a free 30-day evaluation with full functionality, so you can test the complete gateway in your own environment before committing.
