III. Ultimate Comparison of 210/211/212/213 (At a Glance) Table

Model CPU FPU DRAM SCSI Ethernet IP Slot Position / Commonality

210 LC040 ❌ 4MB ✅ ❌ 2 Local storage, mainstream

211 040 ✅ 4MB ✅ ❌ 2 Floating point + storage, rare

212 LC040 ❌ 4MB ❌ ✅ 2 Network control, mainstream

213 LC040 ❌ 4MB ✅ ✅ 2 Top configuration: Network + SCSI, best performance, most commonly used

Four. Core features of 213

Full interface top configuration: Equipped with both Ethernet + SCSI, balancing networking communication and local hard disk storage without trade-offs

Industrial control standard configuration: 4MB memory + 2 IP slots + 4 serial ports, maximum expansion capability, suitable for most VME systems

High compatibility: Can be directly replaced with 210/212, software does not require major modifications, is the preferred choice for upgrading old equipment

Five. Typical applications

Top configuration control for VME systems: VxWorks system, network interface for networking, SCSI for hard drives, data storage + networking both achieved

Upgrading old 210/212: Need to retain both network interface and SCSI functions, directly replace with 213

Multi-device integrated control: 4 serial ports + 2 IP slots, connecting serial devices and fieldbus modules, achieving complex control
