Technical Features & Benefits
At the core of the IC698CRE020-FF is a 700 MHz Pentium III class processor, selected for its balance of computational throughput and deterministic control performance. While raw clock speed is only one metric, what matters in industrial control is the ability to execute logic, scan I/O, and handle runtime data consistently. This CPU module delivers that, even when configured in a hot standby pair.
Redundancy is the defining feature. In a redundant configuration, two identical IC698CRE020-FF CPUs operate in parallel: one as the active controller and the other as the standby. Both modules share I/O status, system time, and internal state information via a redundancy link (often facilitated by a redundancy exchange module like IC698RMX016). Should the active CPU detect an internal fault or lose health confidence, the redundancy system enables the standby CPU to assume control within milliseconds — greatly reducing downtime compared to traditional single-CPU setups.
Memory architecture on the module is also industrial grade. With battery-backed RAM, programs and runtime data survive short power disturbances without loss. Additionally, flash memory stores firmware, configuration files, and system logs, allowing for firmware updates and rollback mechanisms without exposing the system to data corruption.
Communications are another strength. Dual embedded Ethernet ports provide redundancy at the network layer, too — enabling seamless connections to SCADA systems, HMIs, historians, or other controllers. Multiple serial interfaces remain available for legacy devices, bridging older field equipment into a modern control topology. Support for protocols such as Modbus TCP/RTU and SNP allows integrators to design flexible, interoperable networks with fewer protocol conversions or gateways.
From a reliability standpoint, the IC698CRE020-FF module includes safeguards against common industrial threats: thermal de-rating for high ambient operating temperatures, memory error detection, and ongoing CPU self-monitoring. When used in conjunction with proper field wiring practices and environmental enclosures, this redundancy CPU contributes to a system that’s both resilient and maintainable.
