CT11T7F10PN1 PMC676RCTX V2.3 01 16 C1145 CR11 V2.x可以是分布式的或集中式的，主控制和辅助控制可以共存于同一网络上，同时保持功能独立。此外，主控制器可以在不受干扰的情况下监听安全输入，从而降低了复制现场仪器。该系统的核心是一个单板控制器。控制器包含主CPU以及用于与网络I/O通信的冗余以太网驱动程序，以及用于控制网络的附加以太网驱动程序。对于主处理器和I/O模块，采用了实时多任务操作系统。控制软件以非易失性存储器提供，并以灵活的控制块语言编写。它类似于IEEE®854 32位浮点格式，还提供用于复杂的顺序函数图（SFC）。Mark VIe I/O模块由三个基本组件组成：接线板、接线板和I/O包。屏障或箱式接线板放置在接线板上，接线板安装在DIN导轨或底座上的控制柜中。I/O块有两个以太网端口、一个电源、一个本地处理器和一个数据采集板。随着I/O包添加到控制系统中，I/O功能不断增强，允许在单工、双冗余或三冗余配置中使用。由于某些进程子系统需要更高的吞吐量，因此每个I/O包中的本地处理器都会根据应用程序的需要以更高的速率运行算法。在仅输出模块和具有离散输入和输出的组合模块上，可以访问离散输出。具有干式“C”触点的机械继电器是常用的，因为它们可以用于具有不同额定电压的交流和直流电路，提供常开和/或闭合触点，没有泄漏电流，并在仅输出模块和具有离散输入和输出的组合模块上，可以访问离散输出。具有干式“C”触点的机械继电器是常用的，因为它们可以用于具有不同额定电压的交流和直流电路，提供常开和/或闭合触点，没有泄漏电流，并且具有熔断、诊断和电磁阀抑制所需的多功能性。有几种类型的内置螺线管接口可用于节省外部定制熔断和抑制的资金。

CT11T7F10PN1 PMC676RCTX V2.301 16 C1145 CR11V2.x can be distributed or centralized, and primary and secondary controls can coexist on the same network while maintaining functional independence. In addition, the master controller can listen for security inputs without interference, which reduces the replication of field instruments. The core of the system is a single board controller. The controller contains the main CPU and redundant Ethernet drivers for communicating with network I/O, as well as additional Ethernet drivers for controlling the network. For the main processor and I/O module, a real-time multi-task operating system is adopted. The control software is provided in non-volatile memory and written in a flexible control block language. It is similar to IEEE®854 32-bit floating-point format and also provides for complex sequential function graphs (SFC). The Mark VIe I/O module consists of three basic components: a patch board, a patch board, and an I/O package. The barrier or box-type patch board is placed on the patch board, which is mounted in the control cabinet on the DIN rail or base. The I/O block has two Ethernet ports, a power supply, a local processor, and a data acquisition board. As I/O packages are added to the control system, I/O capabilities continue to be enhanced, allowing for use in simplex, dual-redundancy, or triple-redundancy configurations. Because some process subsystems require higher throughput, the local processor in each I/O packet runs the algorithm at a higher rate depending on the needs of the application. Discrete outputs are accessible on output-only modules and combined modules with discrete inputs and outputs. Mechanical relays with dry "C" contacts are commonly used because they can be used on AC and DC circuits with different voltage ratings, provide normally open and/or closed contacts, have no leakage current, and have access to discrete outputs on output only modules and combined modules with discrete inputs and outputs. Mechanical relays with dry "C" contacts are commonly used because they can be used in AC and DC circuits with different voltage ratings, provide normally open and/or closed contacts, have no leakage current, and have the versatility required for fusing, diagnostics, and solenoid valve suppression. There are several types of built-in solenoid interfaces that can be used to save money on external custom fuses and suppression.
