Working Principle: The HE700GEN200 operates as a coprocessor on the Series 90-70 VME backplane. It continuously scans the PLC memory map through dual-port RAM, updating network data buffers with the latest I/O and register values. Simultaneously, it processes incoming network requests from HMI stations, SCADA servers, or other PLCs, writing the received data to the appropriate backplane memory addresses. The module’s internal processor manages all protocol stack processing, TCP/IP socket management, and data conversion, ensuring the main PLC CPU remains dedicated to control logic execution.
