配置

This section provides information on the AC 900F controller configuration forsingle and redundant operation.

本章節提供AC900F控制器單站和冗餘配置的資訊

The AC 900F controller features a modular design. The basic components are aPM CPU module, communication interfaces CI/CM for PROFIBUS and CAN Busand S700 I/O modules. The communication interface CM 772F is not supported byPM 904F.

AC900F採用模組化設計。基本元件為PM CPU模組、為profibus和CAN匯流排以及S700 IO模組通訊使用的CI/CM介面。PM904F不再支援CM 772F通訊介面。

The external 24 VDC voltage required to operate the controller can be provided byan ABB power supply unit such as SD or CP, for example

操作控制器所需的外部 24 VDC 電壓可由 ABB 電源單元（如 SD 或 CP）提供。

2.1 Configuration levels

配置等級

The AC 900 F controller in basic configuration comprises the PM CPU module andTA dummy couplers designed to protect the unused communication slots. The onboardEthernet interfaces and serial interfaces of the CPU module are available for
field communication

AC 900F控制器基本配置包括PM CPU模板和TA虛擬耦合器，旨在保護未使用的通訊插槽。CPU模板上的乙太網介面和串列埠用於現場通訊。

The controller of the medium configuration level is composed of a PM CPU moduleand up to four CI(CM) modules for PROFIBUS communication. Alternatively, aCAN Bus module can be plugged into one of the two slots C1/C2.

中等配置級別的控制器由 PM CPU 模組和最多四個用於 PROFIBUS 通訊的 CI （CM） 模組組成。或者，CAN 匯流排模組可以插入兩個插槽之一 C1/C2

The high configuration level controller is composed of a PM CPU module and up tofour CI(CM) modules for PROFIBUS communication. Alternatively, a CAN Busmodule can be plugged into one of thee two slots C1/C2. S700 I/O modules are usedas “direct I/O”.

高等配置的控制器由PM CPU模組和最多4個用於PROFIBUS 通訊的 CI （CM） 模組組成。或者，CAN 匯流排模組可以插入兩個插槽之一 C1/C2。S700 IO作為直接IO

The S700 I/O modules are connected on the right side of the I/O bus, i.e. they aresimply plugged to the TU terminal blocks that were previously added to the CPUmodules. Up to ten I/O modules can be connected to the I/O bus of the CPU module

S700 IO模組放在IO匯流排右邊連線。也即是說，它們只需要插入之前新增到CPU模板的TU插槽上即可。CPU模板上最多可以插入10個S7 IO模組。

The configuration in the Freelance Engineering hardware structure shouldcorrespond to the actual controller configuration (local DIN rail). Make sure thatthere are no blank TU terminal blocks between the individual I/O modules. I/Omodules connected on the right side of a gap (i.e. of a blank terminal block) are notcontrolled by the CPU module.

freelance工程硬體結構中的配置應與實際控制器配置相對應（本地DIN導軌）。確認單個IO模板之間沒有空的TU插槽。連線在縫隙右側（即空白終端塊）的 I/O 模組不受 CPU 模組控制。
