211 040 ✅ 4MB 128KB ✅ ❌ 2 4MB + Floating Point + SCSI (rare)

212 LC040 ❌ 4MB 128KB ❌ ✅ 2 4MB + Network Port

213 LC040 ❌ 4MB 128KB ✅ ✅ 2 4MB + Network + SCSI (mainstream)

216 LC040 ❌ 8MB 512KB ✅ ✅ 2 8MB + Network + SCSI (high-end)

Four, Key Features of 216

Unique 8MB Large Memory in 200 Series: 8MB DRAM + 512KB SRAM, double the memory compared to 213, suitable for VxWorks multi-tasking, large data caching, and complex control logic

Top-End Interface Combination: Ethernet + SCSI, balancing networking and local storage, no trade-offs

Preferred for High Load Upgrade: Old 213 memory is insufficient or requires a larger cache. Simply replace with 216, software compatibility guaranteed

Five, Typical Applications

High-load VME Control: VxWorks system, multi-tasking, large data caching, complex algorithms, 8MB memory is crucial

213 Memory Expansion Upgrade: The original 213 (4MB) is insufficient, need to retain the network port + SCSI, directly replace with 216

Data Acquisition + Storage + Networking Integration: 4 serial ports + 2 IP slots + SCSI hard drive + Ethernet, one-stop complex control
