IS210BPPBH2CAA 系统和控制器的配置要重点考虑可靠性和负荷率

1、系统和控制器的配置

系统和控制器的配置要重点考虑可靠性和负荷率（包括冗余度）指标。通讯负荷率必须控制在合理范围内，控制器的负荷率尽可能均衡，避免“高负荷”问题的发生。

2、系统控制逻辑分配

系统控制逻辑的分配，不宜过分集中在某个控制器上，主要控制器应采用冗余配置。

3、电源设计

电源设计必须合理可靠。注意电源设计的负荷率和电源的冗余配置方式，保证两路独立电源。

4、DCS系统接口

注重DCS系统接口的可靠性，注意重要接口的接口方式和冗余度。

1. Configuration of system and controller

Systems and controllers are configured with a focus on reliability and load rate (including redundancy). The communication load rate must be controlled within a reasonable range, and the load rate of the controller should be balanced as far as possible to avoid the occurrence of “high load” problems.

2. System control logic distribution

The distribution of the system control logic should not be too concentrated on one controller, and the main controller should adopt redundant configuration.

3. Power supply design

The power supply design must be reasonable and reliable. Pay attention to the load rate of the power supply design and the redundancy mode of the power supply to ensure that the two power supplies are independent.

4, DCS system interface

Pay attention to the reliability of DCS system interfaces, and pay attention to the interface mode and redundancy of important interfaces.
