PST过程安全时间。受控设备的过程安全时间(表示为PSTEUC)是指在没有安全系统作为保护的情况下,危险事件发生之前可能存在的危险状态。R实数一类以浮点、单精度32位格式存储的模拟变量。冗余使用两个或多个设备,每个设备执行相同的功能,以提高可靠性或可用性。分辨率仪器可测量的小间隔;可以表示的细节级别。例如,12位可以区分4096个值。电子工业联盟引入的RS-232-C、RS-422、RS-485标准接口涵盖了数据通信设备之间的电气连接。RS-232-C是常用的接口;RS-422和RS-485允许在增加的距离上实现更高的传输速率。RTC实时时钟。RTU远程终端装置。AADvance控制器支持的MODBUS协议,用于通过串行链路进行MODBUS通信,能够多点连接到多个从设备。
PST Process Safety Time. The process safety time for the equipment under control (denoted PSTEUC) is the period a dangerous condition can exist before a hazardous event occurs without a safety system as a protection. R real A class of analogue variable stored in a floating, single-precision 32-bit format. redundancy The use of two or more devices, each carrying out the same function, to improve reliability or availability. resolution The smallest interval measurable by an instrument; the level of detail which may be represented. For example, 12 bits can distinguish between 4096 values. RS-232-C, RS-422, RS-485 Standard interfaces introduced by the Electronic Industries Alliance covering the electrical connection between data communication equipment. RS-232-C is the most commonly used interface; RS-422 and RS-485 allow for higher transmission rates over increased distances. RTC Real-time clock. RTU Remote terminal unit. The MODBUS protocol supported by the AADvance controller for MODBUS communications over serial links, with the ability to multi-drop to multiple slave devices.
