Engineering Advantages

High-Integrity Redundancy (TMR): The IC697CPM790 supports Triple Modular Redundancy (TMR) through Genius Modular Redundancy (GMR) configurations. In redundant mode, the system votes on 2,048 discrete I/O points, ensuring continuous operation even if a hardware fault occurs. This makes it ideal for emergency shutdown (ESD) and fire and gas (F&G) systems.
Deterministic Math Execution: The integrated Intel 80486DX processor includes a dedicated floating-point unit. This hardware-level math support allows the CPU to execute advanced process control algorithms and complex PID loops without degrading the scan time of the main ladder logic.
Extensive I/O Scalability: One IC697CPM790 manages up to 12,000 discrete I/O points in simplex mode. This massive addressing capability allows engineers to centralize control for entire plant sections—such as turbine control or water treatment facilities—within a single Series 90-70 rack.
Reliable Data Retention: The 1 MB battery-backed RAM secures your ladder logic programs and critical process variables against power loss. Specialized versions of this CPU support up to 8 MB of RAM, providing ample space for data logging and large-scale user programs.
Single-Slot Efficiency: Despite its high-performance 32-bit architecture, the CPU occupies only one slot in the IC697 rack. This compact design maximizes backplane real estate for specialized communication or high-density I/O modules.

FAQs

Can I upgrade an existing Series 90-70 system to use the IC697CPM790?

Yes. The IC697CPM790 fits standard Series 90-70 racks and replaces lower-tier CPUs. However, you must verify that your software (typically Proficy Machine Edition or Logicmaster 90) supports the Intel 486DX 64MHz hardware configuration.
What is the difference between Simplex and Redundant I/O capacity?

In Simplex mode, the CPU addresses the full range of 12,000 I/O points for standard automation. In Redundant (GMR) mode, the system focuses on 2,048 "voted" I/O points to ensure that two or three CPUs agree on the state of a critical safety device before taking action.
How do I manage the memory allocation for ladder logic?

The system reserves up to 512 KB of the base 1 MB RAM specifically for ladder logic programs. You can configure the remaining space for register data, timed interrupts, and system fault tables via the configuration software.
Why is "Brand New" condition mandatory for these CPUs?

The Series 90-70 is a legacy yet vital platform. Used or refurbished CPUs often suffer from dried-out electrolytic capacitors or degraded memory batteries which can lead to "parity errors" and system crashes. A 100% Brand New IC697CPM790 ensures you receive a zero-hour unit with maximum dielectric integrity and a full operational lifespan.
