Proficy SafetyNet是GE智能平台目前提供的主要技术之一，是一种经济、高效的功能安全系统，能够满足当今紧急停车、火气和锅炉管理等方面的安全要求。
坚固的Proficy SafetyNet开放式控制平台结合了Modbus TCP技术，内置容错以太网(FTE)，并支持冗余通信，能够轻松、可靠地连接多种标准的软件和硬件。因此，用户可以进行灵活移植，可以连接传统的控制系统、也可以连接最新的设备和软件，还能够连接新开发的产品。E Fanuc 嵌入式系统是由世界上几个优秀的嵌入式生产厂家发展而成的。被 GE 选择的公司都具有令人尊敬的名字，这些公司都具有引以为豪的业务发展历史，都能够深刻理解用户需求，并且它们都在 GE Fanuc 的发展方向和策略上，起着至关重要的作用。
GE Fanuc 嵌入式系统产品线主要基于开放技术标准，遵循基于 Compact PCI R 、 PCI、PMC、 PC/104-Plus 和 VME标准总线技术体系进行设计，GE Fanuc 也为其它接口形式或按照用户需要定制设计并提供提供相应的服务。GE Fanuc 技术能力包括从CPU 结构、基础构造连贯性到软件集成的广大领域。
an also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The system also supports IEC870-5 over-control protocol.
discussion.
The Flash EPROM inside the PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic ones specified in the IEC 61131 3 standard
In addition to this content, many powerful and rigorously tested function blocks from actual engineering applications have been expanded. any complex control
The scheme can be realized by the combination of these function blocks.
The function blocks provided by the system mainly include the following categories:
o
Analog processing
o
digital processing
loop regulation
Logical sequence control
c
logic operation
Monitoring function
Collection function.
c
arithmetic operations
c
TCP/IP protocol communication interface
Modbus protocol communication interface
1EC870-5 protocol communication interface (Telecontrol)
