PM851AK01输入控制器
ICT模块有足够的内存它可以存储多达30000个点定义（取决于点类型）。ICT模块固件使主机能够发出数据采集、过程监控和控制以及系统功能（安全、时间和配置控制）的命令。ICT模块维护点表并解释来自主机的命令。因此，它指导主机和INFI-NET系统之间的所有交互。ICT模块从INFI 90模块接收数据，然后对数据进行分类、组织和存储在数据库中。NIS模块从INFI-NET系统接收帧，并将其传递给ICT模块进行处理。然后，信通技术模块对这些输入数据进行分类，存储异常报告和输入请求，直到主机准备好接收数据。此缓冲操作允许主机完全与INFI-NET循环异步操作。当主机准备好处理更多数据时，它向信通技术模块发出命令，将数据作为答复转发。MPI模块为ICT模块提供串行端口和SCSI接口。它包含SCSI和RS-232-C I/O端口。计算机传输模块从主机接收命令，执行所需操作，然后回复主机。计算机接口使用80多个命令进行数据采集、过程监控和系统功能（安全、时间、配置）。这些命令分为四种基本命令类型：数据采集、配置、过程控制和系统状态。
数据采集
主机使用ESTABLISH POINT和ESTABLIS REPORT命令在ICT模块中建立数据库。该数据库的容量为10000点（INICI01）或30000点（INCII03），具体取决于点类型。主机可通过数据采集命令访问信通技术模块数据库。可以通过trend DATA POLL命令读取系统中配置的任何趋势块。计算机接口可用于将控制策略配置下载到INFI 90模块。此外，TUNE BLOCK和READ BLOCK OUTPUT命令用于调谐和监控输出。进程控制命令列表为主机提供进程控制功能。主机能够处理模拟和数字过程要求，例如改变设定点和控制输出，将数据值作为异常报告提供给INFI 90模块块，控制和设置数字远程开关和常数。系统状态时间同步是计算机接口的关键功能，也是整体状态的一部分。它使主计算机能够设置和显示系统时间和日期，并提供了将时间戳与系统时间和数据关联的机制。主机能够监控各个模块的状态并提供密码保护。
The ICT module has enough memory
that it can store up to 30,000 point definitions (depending on point types). ICT module firmware enables the host computer to issue commands for data acquisition, process monitoring and control, and system functions (security, time and configuration control). The ICT module maintains the point table and interprets commands coming from the host computer. Thus, it directs all interaction between the host computer and the INFI-NET system. The ICT module receives data from INFI 90 modules and then sorts, organizes and stores the data in a database. The NIS module receives frames from the INFI-NET system and passes them on to the ICT module for processing. The ICT module then sorts this incoming data, storing exception reports and incoming requests until the host computer is ready for the data. This buffering action allows the host computer to operate completely asynchronously to the INFI-NET loop. When the host computer is ready to process more data, it issues a command to the ICT module that forwards the data as a reply. The MPI module provides the ICT module with serial ports and a SCSI interface. It contains SCSI and RS-232-C I/O ports.The computer transfer modules receive a command from a host computer, perform the desired action, and then reply to the host computer. The computer interface uses over 80 commands for data acquisition, process monitoring and control, and system functions (security, time, configuration). These commands fall into four basic command types: data acquisition, configuration, process control, and system status.
Data Acquisition
The host computer uses the ESTABLISH POINT and ESTABLISH REPORT commands to establish a database in the ICT modules. This database has the capacity for 10,000 points (INICI01) or 30,000 points (INICI03), depending on point types. The host computer has access to the ICT module database through data acquisition commands. Any trend block configured in the system can be read through the TREND DATA POLL command.The computer interfaces can be used to download control strategy configurations to INFI 90 modules. Also, the TUNE BLOCK and READ BLOCK OUTPUT commands are used to tune and monitor outputs. Process Control The command list provides process control abilities for the host computer. The host computer is able to handle analog and digital process requirements such as changing setpoints and control outputs, supplying data values to INFI 90 module blocks as exception reports, controlling and setting digital remote switches and constants. System Status Time synchronization is a critical function of the computer interfaces and part of overall status. It enables the host computer to set and display system time and date, and provides a mechanism for relating the time stamp to system time and date. The host computer is able to monitor individual module statuses and provide password protection.
