型号8406-113屋于伍德沃德EGCP-3发动机发电机控制包,负载共享ls)型号系列。这种基于微处理器的装置可与其他LS装置一起使用。8406-113的额定输入电压为18-32 V dc,额定工作温度范围为-20至+70°c。该LS型号具有键盘和显示屏接口,包括两个背光LCD屏幕,使用户能够同时监控和调整相关参数。这些屏幕显示八行状态信息,可选择四行配置或报警日志信息。
使用前,8406-113必须通过首次启动菜单进行配置;当引擎运行时,不能编辑这些项目。
对于标准操作,8406-113配置点可通过前面板显示屏获得。可以通过ServLink通信串行链路从监视窗口软件访问附加配置点(以及标准配置点)。该控制单元有九个状态菜单,便于监控和故障排除。这些菜单是系统状态、发动机状态、发电机状态、同步器状态、KW负载状态PF/KVAR状态、/O状态、序列状态和ATS状态(请注意:LS型号没有任何转换开关功能。如果装置设置为本地系统总线连接到电源,并且MC装置需要执行ATS功能)。
The models 8406-113 are in the Woodward EGCP-3 engine generator control package, load sharing ls model series. This microprocessor based device can be used in conjunction with other LS devices. The rated input voltage of 8406-113 is 18-32 V dc, and the rated operating temperature range is -20 to+70 ° C. This LS model has a keyboard and display interface, including two backlit LCD screens, allowing users to simultaneously monitor and adjust related parameters. These screens display eight lines of status information, with options for four line configuration or alarm log information.Before use, the 8406-113 must be configured through the first boot menu; These items cannot be edited while the engine is running.
For standard operation, the 8406-113 configuration points can be obtained through the front panel display screen. Additional configuration points (as well as standard configuration points) can be accessed from the monitoring window software through the ServLink communication serial link. The control unit has nine status menus for easy monitoring and troubleshooting. These menus are system status, engine status, generator status, synchronizer status, KW load status PF/KVAR status,/O status, sequence status, and ATS status (please note that the LS model does not have any transfer switch function. If the device is set to be connected to the power supply on the local system bus and the MC device needs to perform ATS functions).
PLC控制器本身的硬件采用积木式结构,各厂家产品结构大同小异。以日本欧姆龙C200HE为例,为总线模板框式结构,基本框架(CPU母板)上装有CPU模板,其它槽位装有I/O模板;如果I/O模板多时,可由CPU母板经I/O扩展电缆连接I/O扩展母板,在其上装I/O模板;另一种方法是配备远程I/O从站等。这些都说明了PLC厂家将硬件各部件均向用户开发,便于用户选用,配置成规模不等的PLC,而且这种硬件配置的开放性,为制造商、分销商(代理商)、系统集成商、最终用户带来很多方便,为营销供应链带来很大便利,这是一大成功经验。
