Logic Operation & Control Output: The high-speed processor executes preset logic programs and main control commands, performs linkage operation according to collected signal status, and outputs switch control signals through 16 DO channels to realize on-site equipment start-stop, status switching and interlock protection.
4. Multi-protocol Bus Data Interaction: It uploads I/O status, equipment working conditions and fault information to upper DCS, PLC and SCADA systems via Ethernet and bus interfaces in real time, and receives remote control commands, parameter configuration and logic modification instructions to complete bidirectional system data interaction.
5. Real-time Monitoring & Fault Protection: It continuously monitors power supply status, channel signals, communication links and hardware working conditions. Once abnormal signals, communication interruption, channel faults or voltage anomalies are detected, it locks faults, triggers local alarms, uploads fault codes and shields abnormal outputs to prevent equipment misoperation.
6. Stable Operation & Online Maintenance: It supports long-term uninterrupted stable operation and online parameter modification, protocol switching and fault reset without shutdown, adapting to operation and maintenance requirements of continuous industrial production.
