HollySys FM301 Controller, must have good versatility in hardware design. A standard bus structure should be adopted, and all design indicators should leave a certain margin to allow for expansion when needed. Standard modular structures should be used to minimize secondary development. When equipment or control objects change, or when designing another control system, only minor modifications or expansions are needed for adaptation. Economic efficiency should be high: the performance-to-price ratio of the system design should be as high as possible. Under design requirements, cost-effective components should be used whenever possible; the input-output ratio should be as low as possible, and comprehensive evaluations should be made based on product quality and output, energy consumption reduction, pollution, and labor conditions. System design steps for control systems can generally be divided into three stages: the planning stage, design stage, and debugging stage.
The module reports diagnostic information only when a fault occurs and during the fault. Each channel can be individually configured as channel enabled, meaning the channel is active and diagnostic (default); channel disabled, meaning the channel is inactive, reporting a data value of 0 with no diagnostic information; for unused module channels, it is recommended to configure them in "channel disabled" mode. When an internal module fault or channel fault occurs, the module reports diagnostic information and illuminates the relevant LED indicator. After the fault, the fault light turns off, and fault information is reported. A welcome screen or the main system screen of the controlled system can be used as the main screen, which can navigate to various sub-screens. Each sub-screen should allow one-step return to the main screen. If the controlled main system screen is used as the main screen, it should display some key parameters of the controlled system to provide an overview of the entire controlled system on this screen.
Design of control screens: These screens are primarily used to control the start and stop of controlled equipment and display internal parameters of frequency converters. Parameter settings for frequency converters can also be included in these screens. This type of screen constitutes the majority of touch screen interfaces, with the specific number determined by the actual controlled equipment.
Design of parameter setting pages
This screen is mainly used to set internal parameters of frequency converters and should also display the status of parameter setting completion. Encryption issues should also be considered during actual implementation.
