  对系统部分所做的更改可能会影响系统性能、故障检测时间，并违反工艺安全公差。此部分的条目直接输入SYSTEM section文本窗口。定义•NIO模块-本机输入或输出（I/O）模块。这是指驻留在受信任机箱中的所有I/O模块。它不是指驻留在其他机箱类型中并通过网桥接口模块通信的I/O模块。•双I/O-使用两个表决电路连接到现场设备的模块。•TMR I/O-使用三个表决电路连接到现场设备的模块。rim_interval该值以毫秒为单位指定。它指定了信任TMR接口模块轮询之间必须经过的短时间。对该值的更改将在系统之后立即由系统反映出来。INI文件已加载。格式：•rim_interval=xx•默认值为0.pim_inter瓦尔该值以毫秒为单位指定。它指定了Trusted Communication Interface Module轮询之间必须经过的短时间。对该值的更改将在系统之后立即由系统反映出来。INI文件已加载。格式：•pim_interval=xx•默认值为0.dispancy_val该值以毫秒为单位指定。它规定了TMR处理器报告通道不一致故障之前，TMR输入或输出通道必须不一致的时间。此处应用的值将影响所有TMR NIO模块（非双NIO模块）。Trusted TMR Processor 3.Application Rockwell Automation Publication PD_T8110B/T8110 Issue 22 13下载系统后重新启动TMR处理器之前，不会执行此值的更改。INI文件。格式：•discpancy_val=xx•默认值为2000。dual_discrepancy_val该值以毫秒为单位指定。它规定了在TMR处理器报告通道不一致故障之前，双输入或输出通道必须不一致的时间。此处应用的值将影响所有双NIO模块。在下载系统后重新启动TMR处理器之前，不会执行对该值的更改。INI文件。格式：•dual_discrepancy_val=xx•默认值为2000.ana_discrep_val该值指定为每伏512计数。它规定了TMR处理器指示通道不一致之前，模拟输入通道片的电压读数之间的允许差值。此处应用的值影响所有模拟输入模块（双重和TMR）。在下载系统后重新启动TMR处理器之前，不会执行对该值的更改。INI文件。格式：•ana_discrep_val=xx•默认值=40（40/512伏或78毫伏）。dig_discrep_val对于T8402和T8403，该值指定为每伏512个计数，对于T8423，该值为每伏128个计数。它指定了在TMR处理器指示通道差异之前，T8402、T8403和T8423数字输入通道片的电压读数之间的允许差值。在下载系统后重新启动TMR处理器之前，不会执行对该值的更改。INI文件。Changes made to the System section may affect System performance, Fault Detection times and violate the process safety tolerances. Entries to this section are typed directly into the SYSTEM Section text window. DEFINITIONS • NIO Module - Native Input or Output (I/O) Module. This refers to all I/O modules resident in a Trusted Chassis. It does not refer to I/O modules resident in other chassis types and communicating via a bridge interface module. • Dual I/O - Module using two voted circuits to connect to a field device. • TMR I/O - Module using three voted circuits to connect to a field device. rim_interval The value is specified in milliseconds. It specifies the minimum amount of time that must elapse between polls of Trusted TMR Interface Modules. Changes to this value are reflected by the system immediately after the System.INI file is loaded. Format: • rim_interval=xx • Default is 0. pim_interval The value is specified in milliseconds. It specifies the minimum amount of time that must elapse between polls of the Trusted Communication Interface Modules. Changes to this value are reflected by the system immediately after the System.INI file is loaded. Format: • pim_interval=xx • Default is 0. discrepancy_val The value is specified in milliseconds. It specifies the time that a TMR input or output channel must be discrepant before the TMR Processor reports the Channel Discrepancy fault. The value applied here will affect all TMR NIO Modules (not Dual NIO Modules). Trusted TMR Processor 3. Application Rockwell Automation Publication PD_T8110B/T8110 Issue 22 13 Changes to this value are not implemented until the TMR Processor is rebooted after the download of the System.INI file. Format: • discrepancy_val=xx • Default is 2000. dual_discrepancy_val The value is specified in milliseconds. It specifies the time that a Dual input or output channel must be discrepant before the TMR Processor reports the Channel Discrepancy fault. The value applied here will affect all Dual NIO Modules. Changes to this value are not implemented until the TMR Processor is rebooted after the download of the System.INI file. Format: • dual_discrepancy_val=xx • Default is 2000. ana_discrep_val The value is specified as 512 counts per volt. It specifies the allowed difference between voltage readings of Analogue Input channel slices before the TMR Processor indicates a Channel Discrepancy. The value applied here affects all Analogue Input Modules (Dual and TMR). Changes to this value are not implemented until the TMR Processor is rebooted after the download of the System.INI file. Format: • ana_discrep_val=xx • Default = 40 (40/512 volts or 78 mV). dig_discrep_val The value is specified as 512 counts per volt for T8402 and T8403 and 128 counts per volt for T8423. It specifies the allowed difference between voltage readings of T8402, T8403 and T8423 Digital Input channel slices before the TMR Processor indicates a Channel Discrepancy. Changes to this value are not implemented until the TMR Processor is rebooted after the download of the System.INI file.
