For more detailed information refer to the Mounting and Installation Instructions, I/O Modules for AC 700F / AC 900F.

详见《he Mounting and Installation Instructions, I/O Modules for AC 700F / AC 900F》

Power supply

     An external 24 V DC voltage supply of sufficient power is required for operating the CPU module, the modules on the C1-C4 slots and for the I/O bus. The DC-IN connection is used for power supply. The corresponding supply lines must be connected to the removable 5-pin terminal block.

     保证CPU、C1-C4槽位模块和I/O总线正常运行需要对其外界24VDC电源。直流DC-IN用于电源连接。相应的供电线路必须连接到可移动的5针端子排上.

L+ and M are provided twice, which allows also I/O modules or external sensors to be supplied using these terminals.

L+ 和 M 有两个，允许 I/O 模块或外部传感器使用这些终端供电。

 

The following instructions must be thoroughly read and observed to ensure safe operation

为确保安全，请仔细阅读并遵守以下声明进行操作

• Make sure that the maximum supply voltage (see Section 9, Technical Data) for modules, sensors and other devices is not exceeded. A module supply voltage of more than 32,5 V DC may lead to irreversible damage and destruction of the system.
• 确保给模块、传感器和其它设备的电压不超最大供电电压（参见第九章，技术数据）。模块供电电压超过32.5VDC可能会造成系统不可逆的损坏和破坏。

• Incorrect wiring (e.g. +/- of the power supply is connected to both L+/L+ or M/M) will cause a short circuit. This may trip the fuse of the power supply unit or damage the switch-mode power supply unit. For general information on safety and precautionary measures, please refer to the Safety Instructions for the AC 700F/AC 900F.

• 不正确的接线(例如电源的+/-连接到L+/L+或M/M)将导致短路。这可能会导致电源单元的保险丝断开或损坏开关电源单元。有关安全及预防措施的一般资料，请参阅AC 700F/AC 900F的安全指引。

 

Ethernet interfaces

以太网接口

The on-board Ethernet network interfaces of 100 Mbit/s can be used for communication between the controllers, gateways, control station and engineering stations as well as for Ethernet-based field devices to support Modbus TCP or Telecontrol protocol as per IEC-104

板载100Mbits/s以太网接口可用于控制器、网关和工程站之间的通讯，也可用于基于以太网的现场设备，以支持IEC-104的Modbus TCP或Telecontrol协议。

Serial interfaces

串口

        A removable 9-pin terminal block is used for the connection to both SER1 and SER2 serial interfaces of the CPU module. The SER1 and SER2 interfaces can be configured (and provided with termination resistors) for RS-232 or RS-485 and used for Modbus RTU and Telecontrol protocol as per IEC 60870-5-101 (depending on the terminals used). For more detailed information on the wiring of the series interfaces, please refer to Section 6, Wiring.

CPU模板的串口1和串口2使用可拆除9针端子块。串口1和串口2可以按照IEC 60870-5-101标准（依据段子使用方式）为MODBUS RTU和Telecontrol协议配置为RS-232或者RS-485接线方法（提供终端电阻）。有关系列接口布线的更多详细信息，请参阅第 6 节，接线。

Diagnostic interface 

诊断接口

The third DIAG interface is provided to connect a PC for diagnostics/setting purposes. In addition, a radio clock for time synchronization can be permanently connected to this interface。

提供第三个诊断接口，用于连接 PC 以进行诊断/设置。此外，可以永久连接到此接口的无线电时钟进行时间同步。

上图标注比较简单，不翻译了。

 

A TK 890F/891F diagnostic cable is required to connect the DIAG serial interface with the serial interfaces of the PC. The default transmission rate is 19.2 kBit/s but can be changed to 9.6 kBit/s (see Controller configuration via terminal program on page 91).

需要 TK 890F/891F 诊断电缆才能将 DIAG 串行接口与 PC 的串行接口连接起来。默认传输速率为 19.2 kBit/s，但可更改为 9.6 kBit/s（参见第 91 页的终端程序的控制器配置）.

 

 

Coupler bus 

耦合器总线

The PM CPU module features up to four coupler bus slots for the connection of additional communication interfaces, e.g. CI PROFIBUS modules 

PM CPU 模块具有最多四个耦合总线插槽，用于连接其他通信接口，例如 CI PROFIBUS 模块。

Unused slots must be covered with TA dummy couplers to comply with the ISA 74.01 G3 requirements.

未使用的插槽必须覆盖 TA 虚拟对联器，以符合 ISA 74.01 G3 要求。

 

I/O bus

IO总线

     The I/O bus on the right side of the PM CPU module is provided for communication with I/O modules that are directly connected to the CPU module. This bus serves for exchanging I/O data and diagnostic data between the CPU module and the I/O modules. 

    PM CPU 模块右侧的 I/O 总线提供通信与直接连接到 CPU 模块的 I/O 模块。总线服务在 CPU 模块和 I/O模块 之间交换 I/O 数据和诊断数据。

     Up to 10 TU I/O terminal blocks (one block per I/O module) can be added to the CPU module. For this purpose, the I/O terminal blocks are equipped with a male connector on the left and a female connector on the right side.

     CPU 模块中最多可添加 10 个 TU I/O 终端块（每个 I/O 模块对应一个TU终端块）。为此，I/O 终端块在左侧配备了公头连接器，在右侧配备了母头连接器。（左侧的公头连接器插入前一个IO模块的母头连接器）
