70BA01C-S-HESG447260R2 通信模块卡

型号：70BA01C-S-HESG447260R2

70BA01C-S-HESG447260R2通信模块卡件是一种装有CPU的智能卡，它具有数据处理、接收和发送信息等功能，被广泛应用于程控交换机、路由器、光纤交换机、网卡、无线通信、卫星通信等通信领域 PLC按结构分有整体式和模块式两种，整体型PLC的全部I/O接口的均价格比模块型的低廉，体积小重量轻。因此通常应用在系统工艺生产较为严格的小型控制系统中；模块式PLC的配置灵活，功能扩展方便，提供多种I/O接口或插槽，所以用户能够准确地选择和配置控制系统的I/O接口量，维修时只要更换单元，排除故障的设计也很简单，所以模块型PLC通常应用在复杂系统和大中型控制系统。

    二、I/O模块的选择

    I/O单元的选择应满足与应用控制的匹配。

    对输入单元，应满足数据的电平、传输距离、隔离和供电方式等需求。

    对输出单元，应满足选择的输出单元类型。

    继电器输出单元：价格便宜，选择电压范围大，过载能力较强，因为是触点元件所以操作频率不高。

    晶闸管输出单元：操作频率高，但晶闸管输出仅可以完成交流负载。

    晶体管输出单元：操作频率高，仅可以完成直流控制，过载能力不强。

    此外还要满足系统是否有模拟量I/O等条件。

    四、通信功能的确定

    大中型PLC系统应支持多种现场总线和标准通信协议（如TCP/IP），需要时应能与工厂管理网（TCP/IP）相连接，通信协议应符合ISO/IEEE通信标准，应是开放的通信网络。

    PLC系统的通信接口应包括串行和并行通信接口（RS232C/422A/423/40）、RIO通信口、工业以太网、常用dcs接口等；大中型PLC通信总线（含接口设备和电缆）应1：1冗余配置，通信总线应符合国际标准，通信距离应满足装置实际要表

    PLC系统的通信网络中，上级的网络通信速率应大于IMbps，通信负荷不大于60%。PLC系统的通信网络主要形式有下列几种形式：

    （1）PC为主站，多台同型号PLC为从站。组成简易PLC网络。

    （2）1台PLC为主站，其他同型号PLC为从站，构成主从式PLC网络。

    （3）PLC网络通过特定网络接口连接到大型DCS中作为DCS的子网。

    （4）专用PLC网络(各厂商的专用PLC通信网络。

Model: 70BA01C-S-HESG447260R2

70BA01C-S-HESG447260R2 communication module card is a smart card equipped with CPU, it has data processing, receiving and sending information and other functions, is widely used in program-controlled switch, router, fiber channel switch, network card, wireless communication, satellite communication and other communication fields PLC according to structure divided into integral and modular two. The average price of all the I/O interfaces of the whole PLC is lower than that of the module type, and the volume is small and the weight is light. Therefore, it is usually used in small control systems with strict system process production; Modular PLC configuration flexible, convenient function expansion, to provide a variety of I/O interfaces or slots, so the user can accurately select and configure the control system I/O interface amount, maintenance as long as the replacement of the unit, troubleshooting design is also very simple, so modular PLC is usually used in complex systems and large and medium-sized control systems.

Second, I/O module selection

The I/O unit should be selected to match the application control.

The input unit should meet the requirements of data level, transmission distance, isolation and power supply mode.

For the output unit, the selected output unit type should be satisfied.

Relay output unit: cheap, large selection voltage range, strong overload capacity, because it is a contact element so the operating frequency is not high.

Thyristor output unit: High operating frequency, but thyristor output can only complete AC load.

Transistor output unit: high operating frequency, can only complete DC control, overload capacity is not strong.

In addition, it is necessary to meet whether the system has analog I/O and other conditions.

4. Determination of communication function

Large and medium-sized PLC systems should support a variety of fieldbuses and standard communication protocols (such as TCP/IP), should be able to connect with the factory management network (TCP/IP) when needed, the communication protocol should comply with ISO/IEEE communication standards, should be an open communication network.

The communication interface of PLC system should include serial and parallel communication interface (RS232C/422A/423/40), RIO communication interface, industrial Ethernet, common dcs interface, etc. Large and medium-sized PLC communication bus (including interface equipment and cables) should be 1:1 redundant configuration, the communication bus should meet international standards, and the communication distance should meet the actual requirements of the device

In the communication network of PLC system, the superior network communication rate should be greater than IMbps, and the communication load should not be more than 60%. The main forms of communication network of PLC system are as follows:

(1) PC is the main station, and multiple PLCS of the same model are the secondary station. A simple PLC network is formed.

(2) One PLC is the main station, and other PLC of the same model is the slave station, which constitutes the master-slave PLC network.

(3) The PLC network is connected to a large DCS as a DCS subnet through a specific network interface.

(4) Dedicated PLC network (dedicated PLC communication network of various manufacturers.
