8 Service

维护

This section provides information on maintenance and service operations. As far as the display unit is required for this purpose, its operation is also described.

本章介绍维修保养操作的相关信息。至于为此目的所需的显示单元，也介绍了其操作（方法）。

8.1 Module replacement

模板更换

Unless otherwise specified, the modules must be de-energized prior to connection or disconnection. Make sure to switch off the DC-IN operating voltage, the UP process voltage and additional voltage supply sources, if any.

除非另作说明，否则模块的连接和断开必须断电。确保切断输入的直流电压，如果有UP过程电压和附加电源电压（一并切断）。

8.1.1 CI communication interfaces

CI通讯接口

There are several possibilities to connect or disconnect a communication interface to/from a C1 to C4 slot without disturbing the CPU module

有几种可能在不影响CPU的情况下连接或者断开C1到C4插槽的通讯接口。

AC 900F in de-energized state

AC 900F没有送电状态

After having de-energized the controller, press on the lock at the top of the CI/CM communication interface and disconnect the module from the slot.

在控制器断电后，按下CI/CM接口顶部的锁扣，断开模块与插槽的连接。

AC 900F in energized state

AC 900F 送电状态

The CI 930F, CI 910F and CI 773F communication interfaces are designed for hot plug (connection/disconnection when energized). This does not apply for CM 772F. Make sure that the communication interface concerned is deactivated prior to connection/disconnection. There are two different methods available for this purpose:

CI 910F和CI773F通讯接口热插拔设计（送电状态可连接/断开）。不适用CM 772F（不支持热插拔）。在连接/断开模块之前，请确认通讯接口属于断开状态。为此目的有两种方法：

• using the TD 951 display unit. For more detailed information on the menu operation, please refer to F1 - Module exchange on page 113
• 使用TD 951显示单元。关于菜单操作的更多细节，请参考F1-模板替换，第113页。
• using a PC (terminal program) via the DIAG diagnostic interface。
• 通过诊断接口连接计算机（终端程序）
