GE Fanuc 90-70系列PLC设计指南(中文)
系列90-70可编程控制器系列为客户的应用提供了非常灵活的系统组成方式,利用这些系统组成可以满足现场不同控制对象的要求。当你用这个系列的产品组成控制系统时,所面临的最主要的问题就是系统的组态和配置。一个合适的系统组态会发挥系统中各个组成部分的功能及特点。减少后续工作并大大减少系统所需的投资。但如果选择了一个不合适或不正确的系统组成时,系统的有效性和可靠性会大大降低,甚至于不能正常进行工作,因此在本设计指导手册的第一章中,我们给出了一些典型的系统组成和组态的例子,通过这些构成和组态的例子和图表,你可以了解到GE Fanuc的90-70的各种组成形式。在此基础上可根据实际目的具体情况来选择系统的组态并稍加修改即可。
在本章中所涉及到的内容包括:
·系列90-70基本系统
·系统输出模板
·中断功能
·专用模板
·编程
·协处理器和槽式计算机
·通讯和网络
·人机接口
·系统的冗余容错
can be closed without a permanent connection to the system.
Freelance 800F Process Control Stage
At the process control level, the Freelance 800F system can be controlled by
It consists of a number of process control stations connected to I/O units. you can choose this
Some process stations are in redundant mode (CPU redundancy, fieldbus module redundancy
redundant) or non-redundant mode. Modular pluggable input/output modules
Blocks are freely selected and used according to the type and number of system process signals.
AC800F controller connects remote I/O or field device via fieldbus
ready.
system communication
Communication between operator level and process control level using TCP/IP
Protocol system bus (based on Ethernet), you can choose different
transmission medium such as AUI, twisted pair, fiber optic or coaxial cable.
Freelance OPC server for connecting to higher-level operators
station (800xA) or other OPC client. Freelance Control System
Real-time process values ??and alarms in the system can be accessed via OPC.
We also provide a C language programming interface
