    • A process control and simulator system, such as for use in the manufacture of pharmaceutical products, includes a process control computer which commands and responds to the operation of the process input/output hardware. A simulator computer commands the operation of simulator input/output hardware. The process hardware and simulator hardware are connected by field lines which transfer signals that correspond to the signals that would be produced in actual production operations. The software in the simulator computer not only produces the simulation functions but in addition monitors the outputs from the simulator input/output hardware and records these outputs during the simulation process. The commands produced by the simulator computer, in response to the simulator input/output hardware outputs, are likewise monitored and recorded in a documentation file within a disk drive of the simulator computer. This documentation file serves to document the operation of the process control computer, process hardware, simulator computer and simulator input/output hardware for the purposes of providing validation of the system operation.
    • 过程控制和模拟器系统,例如用于制造药物产品的过程控制和模拟器系统包括控制和响应过程输入/输出硬件的操作的过程控制计算机。 模拟器计算机命令模拟器输入/输出硬件的操作。 过程硬件和仿真器硬件通过现场线路连接,该线路传输与在实际生产操作中将产生的信号相对应的信号。 模拟器计算机中的软件不仅产生模拟功能,而且还监视模拟器输入/输出硬件的输出,并在仿真过程中记录这些输出。 模拟器计算机产生的响应于模拟器输入/输出硬件输出的命令同样被监视并记录在模拟器计算机的磁盘驱动器内的文档文件中。 此文档文件用于记录过程控制计算机,过程硬件,模拟器计算机和模拟器输入/输出硬件的操作,以提供对系统操作的验证。
