PM876 3BDH000607R1 PLC模块控制器 PM-876
PM876 3BDH000607R1 PLC模块控制器 PM-876故障条件下的系统（过程）警报在控制器中以帧速率进行时间标记，并传输到HMI警报管理系统。系统事件以帧速率进行时间标记，接触输入的事件序列（SOE）在I/O包中以1ms进行时间标记。报警可以根据ID、资源、设备、时间和优先级进行排序。操作员可以在报警消息中添加注释，也可以将特定的报警消息链接到支持的图形。标准报警/事件日志存储30天的数据，可以按时间顺序或根据发生频率进行排序。此外，还提供了一个跳闸历史记录，用于存储最近30次跳闸的关键控制参数和警报/事件。
这包括跳闸前后最多200个警报、200个事件、200个SOE消息和模拟数据。数据以英制或公制工程单位显示，更新率为1秒，重新绘制典型显示图形的时间为1秒。可以发出操作员命令来增加/减少设置点，也可以输入新设置点的数值。HMI用户的安全性对于限制访问某些维护功能（如编辑器和调整功能）以及限制某些操作非常重要。提供了一个名为用户帐户的系统，以限制访问或使用特定的HMI功能。
Mark VIe是一个完全可编程的控制系统。应用程序软件由工厂软件自动化工具维护，这些工具选择经过验证的GE控制和保护算法，并将它们与每个应用程序的I/O、排序和显示集成。多个块库提供了通用块、数学块、宏（用户块）和特定于应用程序的块。可以使用多级密码保护对应用程序软件进行更改，并在系统运行时下载到控制器，而无需重新启动主处理器。在冗余控制系统中，每个控制器中的应用软件是相同的，并且对维护人员来说是一个单独的程序。更改的下载由控制系统自动分配到冗余控制器，并且通过诊断监测控制器之间的任何差异。所有应用软件都存储在控制器的非易失性存储器中。
应用软件按顺序运行，动态数据以功能块和梯形图格式显示。维护人员可以添加、删除或更改模拟回路、排序、I/O分配和调整常数。为了简化编辑，可以在屏幕上从一个块到另一个块选择、拖动和放置数据点。还可以将点从应用程序软件图表拖到趋势上。其他功能包括布尔（数字）强制、模拟强制和以应用软件运行的速率（帧速率）进行趋势分析。应用程序软件文档是直接从源代码创建的，可以在网站上编译和打印。这包括应用程序软件图、I/O分配、调整常数的设置等。软件维护工具可在HMI中使用，也可作为基于Windows的计算机上的单独软件包使用。
PM876 3BDH000607R1 PLC module controller PM-876
The system (process) alarm under the fault condition of PM-876 in the PM876 3BDH000607R1 PLC module controller is time tagged in the controller at frame rate and transmitted to the HMI alarm management system. The system events are time tagged at frame rate, and the sequence of events (SOEs) that come into contact with the input are time tagged at 1ms in the I/O package. Alarm can be sorted based on ID, resource, device, time, and priority. Operators can add comments to alarm messages or link specific alarm messages to supported graphics. Standard alarm/event logs store data for 30 days and can be sorted in chronological order or by frequency of occurrence. In addition, a trip history record is provided to store key control parameters and alarms/events for the last 30 trips.
This includes up to 200 alarms, 200 events, 200 SOE messages, and simulated data before and after the trip. The data is displayed in imperial or metric engineering units with an update rate of 1 second, and the time to redraw a typical display graph is 1 second. You can issue operator commands to increase/decrease the set point, or enter the value of a new set point. The security of HMI users is crucial for restricting access to certain maintenance functions (such as editors and adjustment functions) and limiting certain operations. A system called User Account is provided to restrict access or use of specific HMI functions.
Mark VIe is a fully programmable control system. The application software is maintained by factory software automation tools that select validated GE control and protection algorithms and integrate them with the I/O, sorting, and display of each application. Multiple block libraries provide universal blocks, mathematical blocks, macros (user blocks), and application specific blocks. You can use multi-level password protection to make changes to application software and download it to the controller during system operation without restarting the main processor. In a redundant control system, the application software in each controller is the same and is a separate program for maintenance personnel. The modified download is automatically assigned to redundant controllers by the control system and any differences between controllers are monitored through diagnosis. All application software is stored in the non-volatile memory of the controller.
The application software runs in sequence, and dynamic data is displayed in functional block and ladder format. Maintenance personnel can add, delete, or change analog circuits, sorting, I/O allocation, and adjust constants. To simplify editing, data points can be selected, dragged, and placed from one block to another on the screen. You can also drag points from application software charts onto trends. Other features include Boolean (number) forcing, analog forcing, and trend analysis at the rate (frame rate) at which the application software runs. Application software documentation is created directly from source code and can be compiled and printed on a website. This includes application software diagrams, I/O allocation, and setting adjustment constants. Software maintenance tools can be used in HMI or as separate software packages on Windows based computers.
