Serial Communication in Industrial Automation
Serial communication remains widely used in industrial environments for connecting measurement devices, legacy controllers and specialised instrumentation. Interfaces such as RS-232 provide simple, reliable communication between automation equipment and peripheral devices.
Modules like the WAGO 750-650 allow these serial devices to be integrated directly into distributed control systems. By transferring serial data through the fieldbus controller, engineers can incorporate barcode scanners, weighing systems, laboratory instruments and diagnostic tools into PLC-based automation networks.
Typical Applications
- Integration of serial instruments and sensors.
- Communication with barcode scanners and printers.
- Connecting weighing systems and measurement devices.
- Data exchange with legacy RS-232 industrial equipment.
- Industrial monitoring and diagnostic systems.
