HITACHI LPA220A端子模块
1.产 品 详 情 资 料：
确保SM链路电缆TK852V010在热插拔和OLU之前已连接。如果需要，可以更换SM链路电缆TK852V010，热插拔和OLU期间除外。卸下电缆会导致诊断错误，必须修理或更换电缆。非SIL和SIL1-2应用程序不受SM811同步的影响。它们在整个同步过程中继续正常执行，而不会被中断。SM811的热插拔要求两个安全模块通过同步链路连接，用于传输应用程序状态。在热插拔期间，无法从Control Builder下载新配置，因为控制器是保留的。控制生成器用户会收到一个信息对话框的通知。当热插入结束或中止时，保留将被释放。如果正在进行配置下载，则在下载完成后开始热插拔。关键功能•提供一个PROFIBUS DP端口（位于TP851基板上的DB9母连接器）。•简单的DIN导轨安装•CI851处理PROFIBUS DP上从设备的循环读写消息。然而，最小循环时间可以是1ms，但这将取决于所使用的波特率和连接的从设备的数量。•通过使用中继器，可以将最多124个节点连接到一个PROFIBUS DP（一个网段上允许32个节点）。•安装在机组底座中的预设两个字母的阿尔法代码锁定装置可防止安装不兼容的组件。
Make sure that SM Link Cable TK852V010 is connected before hot-insert and OLU. The SM Link Cable TK852V010 can be replaced if needed, except during hot-insert and OLU. Removing the cable results in a diagnostic error and the cable must be repaired or replaced. Non-SIL and SIL1-2 applications are not affected by synchronization of SM811. They continue to execute as normal throughout the entire synchronization without being interrupted. A Hot Swap of SM811 requires the two safety modules to be connected with a synchronization link, used to transfer the application state. During a hot swap it is not possible to download a new configuration from Control Builder, the controller is reserved. The Control Builder user is notified with an information dialog. The reservation is released when the hot insert is concluded or aborted. If a configuration download is ongoing, then the hot insert starts after the download is completed.Key Features • Provides one PROFIBUS DP port, (a DB9 female connector located on the TP851 Baseplate). • Simple DIN-rail mounting • The CI851 handles cyclic read and write messages to the slaves on the PROFIBUS DP. The minimum cycle time can be 1 ms, however, but this will depend on the baud rate used and the number of attached slaves. • By using repeaters it is possible to connect a maximum of 124 nodes to one PROFIBUS DP (32 nodes are permitted on one segment). • Pre-set, two-letter Alpha code locking device installed in unit base prevents mounting of incompatible components.
