ABB  07KT98 H2 GJR5253100R0278  可编程处理器单元 一般不需要扩展，当系统较大时，就要扩展。不同公司的产品，对系统总点数及扩展模块的数量都有限制，当扩展仍不能满足要求时，可采用网络结构。有些厂家产品的个别指令不支持扩展模块，因此，在进行软件编制时要注意当采用温度等模拟模块时，各厂家也有一些规定，请看相关的技术手册。各公司的扩展模块种类很多，如单输入模块、单输出模块输入输出模块、温度模块、高速输入模块等。

ABB  07KT98 H2 GJR5253100R0278  可编程处理器单元 当用PLC进行网络设计时，其难度比PLC单机控制大得多 首先你应选用自己较熟悉的机型，对其基本指令和功能指令有较深入的了解，并且指令的执行速度和用户程序存储容量也应仔细了解。否则，不能适应你的实时要求，造成系统崩溃。另外，对通信接口、通信协议数据传送速度等也要考虑。最后，还要向PLC的商家寻求网络设计和软件技术支持及详细的技术资料，至于选用几层工作站，依你的系统大小而定。

The ABB 07KT98 H2 GJR5253100R0278 programmable processor unit generally does not need to be expanded, and must be expanded when the system is larger. The products of different companies have limitations on the total number of system points and the number of expansion modules, and when the expansion still cannot meet the requirements, the network structure can be used. Some manufacturers of individual instructions do not support the expansion module, therefore, in the software development should pay attention to when the use of temperature and other simulation modules, the manufacturers also have some provisions, please see the relevant technical manual. There are many types of expansion modules, such as single input module, single output module, temperature module, high-speed input module and so on.

ABB 07KT98 H2 GJR5253100R0278 Programmable processor unit When using PLC network design, its difficulty is much greater than PLC single machine control First of all, you should choose your own more familiar model, have a deeper understanding of its basic instructions and functional instructions, And instruction execution speed and user program storage capacity should also be carefully understood. Otherwise, it can not adapt to your real-time requirements, resulting in a system crash. In addition, the communication interface, communication protocol data transmission speed should also be considered. Finally, but also to the PLC business to seek network design and software technical support and detailed technical information, as for the choice of several layers of workstation, depending on the size of your system.
