Network Communication & Firmware Flash Compatibility
The IC693CPU374-GV incorporates dual-processor architecture to maintain stable logic cycle times alongside concurrent network operations. The module relies on precise firmware flash compatibility between its main control runtime and the embedded Ethernet subsystem to avoid data packet drops during periodic data exchange.
The integrated switch supporting daisy-chain network topologies routes incoming Profinet or EtherNet/IP deterministic networks directly through the communications processor, segregating industrial Ethernet traffic from the core backplane bus. Ensuring matching firmware baselines prevents communication velocity latency degradation and allows full execution of PLC programming, configuration, and diagnostics services without interrupting active control loops.
Frequently Asked Questions
Q: Does the IC693CPU374-GV support hot-swapping or run-time removal?
A: No. The Series 90-30 backplane architecture requires full electrical isolation prior to module insertion or removal. Attempting to swap the CPU module while power is applied will cause memory corruption, bus faults, and potential hardware damage.
Q: How is the volatile memory protected during a complete loss of main rack power?
A: Program storage and user logic variables are maintained via a replaceable lithium battery pack connected to the module front face. If the battery voltage drops below the critical threshold, the diagnostic LEDs will trigger an I/O fault, indicating memory retention is at risk during the next power cycle.
Q: What is the technical function of the dual RJ45 ports if the module only uses one IP address?
A: The two ports connect to an internal embedded Ethernet switch. This layout allows for linear or daisy-chained network topologies between adjacent PLC nodes without requiring an external standalone network switch component.
Field Installation Guidelines
- Chassis Attachment: Ensure the rack power supply is locked out. Slide the module into the designated slot of the Series 90-30 baseplate, ensuring the rear pivoting hook engages the chassis notch properly before securing the bottom latch.
- Shielding Ground Base: Terminate the copper Ethernet cable shields to the outer metal casing of the RJ45 connectors to ground transient electrical noise via the backplane frame.
- Serial Comm Separations: Route the RS-232/RS-485 serial communication cables through physical wire paths away from three-phase AC power cables or motor drive outputs to prevent induction interference.
- Thermal Convection: Maintain the manufacturer's recommended vertical spacing clearances around the PLC rack assembly to permit ambient airflow across the passive cooling vents.
