The Emerson VersaMax CPUE05 (ordering code IC200CPUE05) is the top-tier CPU for the VersaMax modular PLC platform, adding 10BaseT Ethernet to the same 64-module/2048-point I/O capacity as the CPU001. With 128KB of configurable user memory (nearly 4× the CPU001), SRTP Server, EGD peer-to-peer data exchange, and 0.8ms/K boolean execution — less than half the CPU001's scan time — it targets networked machine control and SCADA-connected process skids.

What Ethernet capabilities does the CPUE05 add?

The embedded 10BaseT RJ-45 port supports SRTP Server (8 simultaneous connections) for HMI and SCADA communication, plus EGD (Ethernet Global Data) for controller-to-controller peer data exchange — up to 32 configuration-based exchanges with 100 data ranges per exchange. EGD selective consumption lets the CPUE05 subscribe only to the data it needs from each producer, conserving bandwidth. NTP client capability synchronizes the real-time clock to plant-wide time servers. For programming, the Ethernet port supports firmware downloads via WinLoader in addition to serial-port programming through VersaPro or Machine Edition.

How does the CPUE05 compare to the CPU001?

Beyond Ethernet, the CPUE05 doubles the memory footprint to 128KB — critical for applications with extensive recipe storage, data logging, or complex sequencing. Boolean execution speed improves from 1.8ms/K to 0.8ms/K, making it viable for machines with moderately fast cycle times. The CPUE05 is physically larger (126mm wide vs 66.8mm for the CPU001) and requires a PWRx02 power supply with expanded 3.3V rail. Both CPUs share the same VersaMax I/O and communication module ecosystem, the same programming toolchain, and the same 0–60°C operating range. The CPUE05 also adds a super-capacitor for 1-hour memory retention during battery changes.
