The IC695/IC693 system architecture utilizes the integrated 133 MHz processor on the IC693CPU372 to process application code and manage backplane bus communication velocity across local and expansion baseplates. Internal memory buffers directly interface with the dual RJ-45 Ethernet ports, enabling real-time Ethernet Global Data (EGD) transfers and Modbus TCP messaging without placing additional protocol overhead on the primary CPU logic scan loop.
Firmware flash compatibility ensures long-term operational adaptability across field updates. The dual Ethernet ports operate through an internal switch to allow daisy-chain topologies, while the CPU supports up to 2048 discrete and 32,640 analog I/O points across seven expansion and seven remote baseplate configurations to optimize total I/O density scaling.
Q: How is program memory retained on the IC693CPU372 during system power outages?
A: Program and register memory reside in internal RAM maintained by a backplane battery backup, with optional non-volatile flash memory available for battery-independent retention.
Q: Do the dual Ethernet ports on the IC693CPU372 require separate IP address configurations?
A: No. The two RJ-45 Ethernet ports share the same IP address and function via an integrated internal switch, allowing daisy-chain network wiring.
Q: What software package is used to program the logic and Ethernet interfaces of this CPU?
A: Programming and configuration are performed using Proficy Machine Edition (PLC Logic Developer) or via the built-in web server interface for basic diagnostics.
