Industrial Communication Protocols
Modern manufacturing lines require torque tools to be fully integrated into the plant automation architecture. The torque controller must receive start and program-select signals from the PLC, return OK/NG results to halt the line on a non-conforming fastening, and simultaneously push torque data to the MES for traceability and quality analysis. TMG designs and implements these integrations using the industrial protocols your plant infrastructure already supports.
Integration Capabilities
- OPC-UA server/client implementation: fully compliant OPC-UA communication for torque data exchange with Allen-Bradley, Siemens and other PLC platforms — the preferred protocol for industrial fastening systems
- EtherNet/IP and Profinet adapter: native adapter cards and configured communication profiles for seamless integration with existing plant PLC infrastructure
- Real-time torque data to MES: cycle-by-cycle torque, angle, timestamp and VIN data pushed to your manufacturing execution system immediately upon cycle completion
- PLC signal outputs (OK/NG, start, stop): discrete I/O and fieldbus signals for line interlock — prevent the line from advancing on a non-conforming fastening result
- Multi-station network topology: design and implementation of scalable network architecture connecting multiple assembly stations with centralized data collection
- Custom integration for existing systems: interface development for proprietary MES and quality management systems already deployed in your plant
