IS200VROCH1BBR模块卡件,脉冲输入卡件
在接收到配置数据后，如果来自的数据正常，则板OK D打开；如果存在配置错误，则关闭。当与一个或多个扩展器建立通信并且扩展总线正常运行时，较低的D标记端口OK（正常）打开。一旦sysm启动并运行，当任何配置的扩展响应时，此D将打开。当一个配置的扩展响应时，PORT OK D关闭扩展器。扩展器上有一个D。当基本转换器等待扩展器配置数据时，此D闪烁。当配置扩展器时，D打开。当检测到板故障时，D关闭。报警输入诊断包括报警参数功能和故障报告在内的报警输入诊断如下所述报警参数功能报警参数功能在输入超出指定操作范围时提供均值初始化特殊处理。报警阈值可以设置在信号动态范围内的任何位置。通常，它们被设置为超出输入不应工作的速度或超出需要处理的速度。它们也可以设置在信号的动态范围之外，以确保它们永远不会被激活。期望的操作范围由用户可配置的高阈值和低阈值定义。报警不会影响SCADA输入值的操作或改变其范围。报警参数功能仅在基本转换器上可用。报警触点当scad输入值超出任一配置阈值时，相应的高[HIALR]或低[LOALR]报警触点通电。每次超过报警阈值时都会产生一个报警。IC支持每个Base Converter的一个[HIALR]和一个[LOALR]触点。报警中断此外，如果配置中有ebd，则任一报警也将生成触发的梯形图中断。IC支持用于ea输入的separa触发中断块。当发生报警中断时，更新为激活中断块之前的数据。在中断块内，逻辑可以通过检查输入数据来确定何时发生报警。Alog Input Sysm High level s F Alog s August Controlr数据表F警告：中断可能会中断任何程序块（包括_in块）的执行。因此，如果中断块和程序块访问相同的数据，可能会出现未预期的结果。当程序块和中断块需要访问相同的数据时，可以使用SVCREQ#临时阻止在访问共享数据时执行中断。由中断触发的块的执行取代rl程序序列的执行。rl程序的执行被暂停，仅在中断块ps后恢复。报警配置Ea Base Converter可配置为具有高阈值值和低阈值值。蓝色是。高阈值必须大于低阈值。阈值限制基于缩放。如果缩放被更改，则检查并重新调整报警阈值（如有必要）。报警阈值禁用相应的报警，因此可能只有高报警或低报警。默认情况下，高报警阈值和低报警阈值分别设置为+和。可以使用本数据表中其他地方描述的诊断配置数据动态更改报警阈值。使用报警触点时，需要按照适用的控制器参考中的描述将点故障记录在中。故障报告IC警报输入支持在中激活故障[FULT][FL T]梯形触点时进行故障检测。此外，如果配置中禁用了故障报告，则故障选项卡中会记录相应的故障信息。如果配置中的故障报告是ebd，则故障状况会报告一次，并且不会再次报告，直到故障状况被消除，然后再次发生。故障触点上的任何以下故障都将导致相应的故障触点通电。IC支持Base Converter和Expander上每个输入一个[FULT]和[FL T]触点。
Afr receiving configuration data the Board OK D is turned on if the data from the is OK; it is turned off if there is a configuration error. The lower D labed PORT OK turns on when munication is established with one or more Expander s and the expansion bus is operating properly. Once the sysm is up and operating this D is turned on when any of the configured expansion s are responding. When ne of the configured expansion s are responding the PORT OK D is turned off Expander s There is one D on an Expander . This D flashes when the Base Converr is waiting for Expander configuration data. The D is turned on when the Expander is configured The D is turned off when a board failure has been decd. Alog Input Diagstics Alog input diagstics including the Alarm parar Function and fault reporting are described below Alarm parar Function The Alarm parar Function provides a meanism initia special processing when an input goes outside a specified operating range. Alarm Thresholds can be set anywhere over the dymic range of the sigl. Typically they are set at vels beyond whi the input should t opera or vels beyond whi alr processing is required. They can also be set beyond the dymic range of the sigl ensuring that they will never be actid. The desired operating range is defined by user configurab high and low thresholds. The alarms do t affect operation of the or ange the scad input lue. The Alarm parar function is ailab only on the Base Converr . Alarm Contacts When the scad input lue goes outside either of the configured thresholds the appropria high [HIALR] or low [LOALR] alarm contact for the is energized. One alarm is generad ea time an alarm threshold is crossed. The IC supports one [HIALR] and one [LOALR] contact per of the Base Converr . Alarm Inrrupts In addition either alarm will also genera a triggered ladder inrrupt if ebd in the configuration. The IC supports a separa triggered inrrupt block for ea input . When an alarm inrrupt occurs the updas the data for that before actiting the inrrupt block. Within the inrrupt block the logic can dermine whi alarm occurred by examining the input data. Alog Input Sysm High vel s F Alog s August Controlr Data Sheet F Caution An inrrupt can inrrupt execution of any program block including the _in block. Therefore unexpecd results can occur if the inrrupt block and the program block access the same data. When it is necessary for a program block and an inrrupt block access the same data a SVCREQ # can be used mporarily block the inrrupt from executing when the shared data is being accessed. The execution of a block triggered from an inrrupt supersedes the execution of the rl program sequence. Execution of the rl program is suspended and only resumed afr the inrrupt block ps. Alarm Configuration Ea Base Converr can be configured have a high and a low threshold lue. lues are . The high threshold must be grear than the low threshold. Threshold limits are based on scaling. If scaling is anged review and readjust the Alarm Thresholds if necessary. that an alarm threshold of disabs the corresponding alarm thus it is possib have only a high or low alarm. By default the high and low alarm thresholds are set + and respectively. The alarm thresholds can be anged dymically using the Diagstic Config Data nd described elsewhere in this data sheet. Use of alarm contacts requires that Point Faults be ebd in the as described in the applicab Controlr Reference . Fault Reporting The IC Alog Input s support fault dection whi is used acti fault [FAULT] [FL T] ladder contacts in the . In addition a corresponding fault message is logged in the Fault Tab unss fault reporting has been disabd in the configuration. If fault reporting is ebd in the configuration ea fault condition is repord once and is t repord again until the fault condition is removed and then occurs again. Fault Contacts Any bition of the following faults on a will cause the corresponding fault contact be energized. The IC supports one [FAULT] and [FL T] contact per input on both Base Converr and Expander s.
