8.1.2 I/O modules

IO模板

The I/O bus of the CPU module is not designed for the connection anddisconnection of I/O modules during operation.

CPU模組的IO匯流排設計為不能再IO模板操作時連線和斷開。

If an I/O module is connected or disconnected while the system is operating, anunintentional reset or lock up of the controller may be caused.

如果一個IO模板在系統操作時連結或者斷開，可能導致控制器的復位或者鎖定。

8.2 Replacement of accessories

附件的替換

8.2.1 TD 951F

TD 951F顯示單元

If only one display unit is provided, for instance, this unit can be removed from acontroller and connected to another controller during operation. A previousdeactivation of the TD 951F is not required for this purpose. Press the upper andlower snap-in noses simultaneously to remove or install the TD 951F

如果只提供一個顯示單元，例如，這個單元可以從一個控制器移到另一個控制器，為此目的，就不需要停用TD 951F。同時按下上部和下部的卡鼻，取下或者安裝TD 951F。

8.2.2 Battery change

電磁更換

Replace the battery with the controller supply voltage ON in order to avoid any dataloss.

在控制器有電的情況下更換電池可以避免資料丟失。

Remove the detachable front panel of the CPU module or the display unit installedin this position. For electrical disconnection, carefully unplug the small connectorfrom the battery socket. The used battery can then be removed from the batterycompartment or the battery holder by carefully pulling the battery cable. Insert thenew battery as described under Insertion of the TA 951F battery on page 89.

將該位置（電池位置）的CPU模板的可拆卸前面板或者顯示單元拆掉。因為沒有斷電，小心的拔出電池插座上的小的聯結器，用過的電池可以通過小心的拉動電池線從電池箱中或者電池支架中取出。按照第89頁ta951f電池的插入說明插入新電池。
