2 Configuration

配置

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

本章節(jié)提供AC900F控制器單站和冗余配置的信息

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

AC900F采用模塊化設(shè)計?；窘M件為PM CPU模塊、為profibus和CAN總線以及S700 IO模塊通訊使用的CI/CM接口。PM904F不再支持CM 772F通訊接口。

The external 24 VDC voltage required to operate the controller can be provided by an 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 and TA dummy couplers designed to protect the unused communication slots. The onboard Ethernet 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信插槽。CPU模板上的以太網(wǎng)接口和串口用于現(xiàn)場通訊。

     The controller of the medium configuration level is composed of a PM CPU module and up to four CI(CM) modules for PROFIBUS communication. Alternatively, a CAN 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 模塊和最多四個用于 PROFIBUS 通信的 CI （CM） 模塊組成?；蛘?，CAN 總線模塊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 to four CI(CM) modules for PROFIBUS communication. Alternatively, a CAN Bus module can be plugged into one of thee two slots C1/C2. S700 I/O modules are used as “direct I/O”.

高等配置的控制器由PM CPU模塊和最多4個用于PROFIBUS 通信的 CI （CM） 模塊組成。或者，CAN 總線模塊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 are simply plugged to the TU terminal blocks that were previously added to the CPU modules. Up to ten I/O modules can be connected to the I/O bus of the CPU module

S700 IO模塊放在IO總線右邊連接。也即是說，它們只需要插入之前添加到CPU模板的TU插槽上即可。CPU模板上最多可以插入10個S7 IO模塊。

     The configuration in the Freelance Engineering hardware structure should correspond to the actual controller configuration (local DIN rail). Make sure that there are no blank TU terminal blocks between the individual I/O modules. I/O modules connected on the right side of a gap (i.e. of a blank terminal block) are not controlled by the CPU module.

freelance工程硬件結(jié)構(gòu)中的配置應(yīng)與實際控制器配置相對應(yīng)（本地DIN導軌）。確認單個IO模板之間沒有空的TU插槽。連接在縫隙右側(cè)（即空白終端塊）的 I/O 模塊不受 CPU 模塊控制。
