HITACHI LPA210A自动化控制模块
1.产 品 详 情 资 料：
说明HITACHI LPA210A/TP851用于连接到远程I/O。通过PROFIBUS DP上的外部网关，现场仪表（PROFIBUS DP上）可以连接到AC 800M。TP851基板有一个内螺纹DB9连接器，用于连接PROFIBUS DP。底板有一个代码锁，见第75页表4，可防止在TP851底板上安装不正确类型的装置。HITACHI LPA210A扩展单元包含CEX总线逻辑、通信单元和DC/DC转换器，该转换器通过CEX总线从+24 V电源提供适当的电压。PROFIBUS DP必须始终端接在两个外部节点。ABB建议使用带有内置端接的连接器，因为即使现场总线与装置完全断开，也会始终端接。功能框图图69。方框图–HITACHI LPA210A HITACHI LPA210A已被CI854通信接口所取代。HITACHI LPA210A仅因遗留原因而被描述。检测到F（故障）/红色单元错误。由控制软件控制。在控制器重置期间由硬件设置并清除。R（un）/绿色运行。由控制软件控制。在控制器重置过程中被硬件清除。Rx/Tx/黄色传输到装置或从装置传输。RTS/黄色请求从装置发送。
escription HITACHI LPA210A / TP851 is used for connecting to remote I/O. Via an external gateway on PROFIBUS DP, field instruments (on PROFIBUS DP) can be connected to AC 800M. The TP851 Baseplate has one female DB9 connector for connecting PROFIBUS DP. The baseplate has a code lock, see Table 4 on page 75, that prevents the installation of an incorrect type of unit onto the TP851 Baseplate. The CHITACHI LPA210Aexpansion unit contains the CEX-Bus logic, a communication unit and a DC/DC converter that supplies appropriate voltages from the +24 V supply, via the CEX-Bus. The PROFIBUS DP must always be terminated at the two outer nodes.ABB recommends the use of connectors with built-in termination since the fieldbus will always be terminated even if fully disconnected from the unit.
