Serial Communication in Industrial Automation
Despite the growth of Ethernet-based industrial networks, RS-232 communication is still widely used for connecting specialised instruments and legacy industrial equipment. Devices such as barcode scanners, weighing systems, diagnostic tools and laboratory analysers frequently use serial interfaces for reliable data exchange.
The WAGO 750-650/000-001 allows these devices to be integrated directly into PLC automation systems. By transferring serial data through the fieldbus controller, engineers can connect serial equipment to modern control platforms and centralise monitoring within industrial automation networks.
Typical Applications
- Connecting barcode scanners and printers.
- Integrating weighing systems and measurement instruments.
- Communication with legacy RS-232 industrial equipment.
- Factory data acquisition systems.
- Industrial diagnostics and monitoring systems.
