Comparison with Other MVME – 147 Models (e.g., MVME – 147SC – 2)
Processor Differences: The MVME – 147SC – 2 offers more advanced processor options, such as the 32 MHz MC68040 enhanced 32 – bit microprocessor with cache, MMU, and FPU. In contrast, the MVME – 147 – 011A features the 25 MHz MC68030 enhanced 32 – bit microprocessor. While the MC68030 is a capable processor, the MC68040 in the MVME – 147SC – 2 generally provides higher – performance processing capabilities, especially for applications that demand complex numerical calculations and advanced memory management.
Memory Variations: The MVME – 147SC – 2 offers more flexibility in memory configuration, with options of 4, 8, or 16 MB of shared DRAM. In comparison, the MVME – 147 – 011A has a fixed 4 MB of DRAM. This makes the MVME – 147SC – 2 more adaptable to applications with diverse memory needs, whether they are cost – sensitive or require more memory for data – intensive operations.
Unique Feature in MVME – 147 – 011A: The MVME – 147 – 011A has four EIA – 232 – D serial communications ports, which is a higher number compared to the two serial ports in the MVME – 147SC – 2. This can be an advantage in applications where a large number of serial – based devices need to be interfaced, such as in some industrial control systems with a high density of legacy sensors and actuators.
Typical Application Scenarios
Industrial Automation in Manufacturing Plants: In a manufacturing plant, the MVME – 147 – 011A can be used as a central control unit for various automated processes.
