The price of Yueyang Tongtu is reasonable. If you need it, please feel free to come and purchase at any time. The Prosoft MVI71-ADM is specially designed for SLC 500 processors, providing an independent operating space, allowing you to run your own written C language programs, perform calculations, and then directly deliver the results to the SLC (System Level Controller). This will not slow down the operation speed of the main CPU, and can achieve functions that were previously considered impossible. If it malfunctions, all your complex algorithmic logic will be paralyzed, so it is a key component for enhancing the intelligence level of outdated systems.
