Building upon the previous focus on hot runner digital interface selection and adaptation verification, the linkage between hot runner sensor data and the MES system can be implemented through the following process:
Hardware Interface Layer: Utilizing Profinet/EtherNet/IP industrial Ethernet digital interfaces, real-time data from the hot runner temperature sensors is connected to the local PLC, completing signal standardization conversion.
Protocol Integration Layer: Using the OPC UA protocol as an intermediary, bidirectional data communication between the PLC and the MES system is achieved, ensuring stable data transmission without packet loss.
Function Implementation Layer: A data dashboard is configured in the MES system to synchronize real-time information such as temperature and over-temperature alarms at various points in the hot runner, linking it to injection molding work orders for process data traceability.
Stability Guarantee: An opto-isolation module is added to the communication link to avoid strong electromagnetic interference around the hot runner, ensuring long-term reliable data transmission.
This solution enables efficient linkage between hot runner sensor data and the MES system, adaptable to most injection molding workshop scenarios.
