As can be seen from the above, the mode of pure hardware redundancy has more hardware input and greater cost. And software redundancy, only need to add a CPU module, the cost increase is very small, because generally like CPU this PLC heart, manufacturers will be equipped with spare parts, with spare parts to achieve redundancy control, not only improve the reliability and maintainability of the system (can do online maintenance, does not affect the operation of the production line), but also will not significantly increase the cost.

From the perspective of reliability analysis, pure hardware redundancy has no advantage over software redundancy. Because more components and modules are added, the failure of these components and modules may affect system reliability. For example, if the cable connecting two hot spare modules is faulty, the redundancy control will also fail. With software redundancy, only one CPU module is added, and the failure rate of two CPU modules at the same time is almost zero.

One of the advantages of pure hardware redundancy is that there is no need for specialized software programming. CPU status monitoring and control transfer are accomplished by two hot spare modules. In software redundancy, the status monitoring and control transfer of two CPU modules are solved by software programming. Therefore, software redundancy programming is relatively complicated and the workload is larger.
