Wide compatibility with a broad range of PLCs and intelligent controllers that have communication ports, enabling easy integration and improved control efficiency. Realtime monitoring and control: view and modify values and states of the PLC internal registers or relays using text display or indicator lights, allowing operators to manage equipment directly and confidently. Easy data transfer to the display: the communication protocol and screen data can be downloaded to the display without the need to write a PLC communication program. Durable and reliable construction: made of ABS material with an original imported chip, providing good antishock performance and stable operation. Practical and dependable performance: designed for stable operation in industrial environments, emphasizing reliability and longterm use. Use scenarios Scenario 1: Manufacturing line integration. Connects to various PLCs and intelligent controllers to monitor and adjust register values and relay states from a central display, improving control accuracy and throughput. Scenario 2: Maintenance and debugging. Technicians download protocol and screen data to verify PLC operation without writing communication programs, speeding up diagnostics. Scenario 3: Packaging or processing lines requiring quick human oversight. Operators use text readouts and indicator lights to respond promptly to PLC state changes and maintain smooth production flow.
