Ethernet/Industrial Protocol Or Ethernet/IP (EIP) Specifies How CIP Communication Packets Can be Transported Over Standard Ethernet and TCP/IP Technology.

• CIP: Control traffic (a.k.a. Implicit traffic)

I/O control, drive control, Produced/Consumed tags

Uses UDP protocol (multi-cast and uni-cast)

• CIP: Information traffic (a.k.a. Explicit traffic)

HMI, MSG’s, Program upload/download

Uses TCP protocol

• Other common traffic

HTTP, Email, SNMP, etc.

Ethernet/IP Traffic Types in a

Control Environment

Advantages of EtherNet/IP

Based upon standard Ethernet and IP Protocol suite

Established—150+ registered vendors

Future proof—Runs on unmodified standard Ethernet

Supported—All EIP products require conformance testing

Standard to integrate I/O control, device configuration and data collection in automation and control systems

Supports three network protocols. EtherNet/IP is based on Ethernet, IP and TCP/UDP

Supported by the Open Device Vendor Association(ODVA)

Key communication includes:

Implicit messaging—Real-time I/O data, functional safety data, motion control data, often UDP multicast

Explicit messaging—Configuration, diagnostics, data collection, based on TCP unicast messaging

ODVA: www.odva.org

OSPF

• 通过UDP 协议传送I/O控制数据,将UDP报文映射到IP组播传送,实现高效I/O交换,有力支持了CIP的生产者/消费者模式。

Port Types and Status Description

REP port A port that is configured to run the REP protocol.

Edge port A port that terminates the segment

Alternate Port A port in the segment that blocks VLANs to prevent loops. The Alternate Port may be any port in the segment. There are two alternate ports per segment if VLAN load balancing is configured.

Open port A port in the segment forwarding on all VLANs

•REP guarantees there is no connectivity between two edge ports on a segment.

•A REP segment is a chain of ports connected to each other and configured with a segment ID.

•When all interfaces in the segment are UP, the alternate port is blocking

• When a link or switch failure occurs on the segment, then blocked port goes forwarding

• Compare test with same topologies with fiber vs. copper uplinks

Multimode LC fiber cables

Cat 5e and Cat 6 copper cables

• All fiber topologies converged faster than copper topologies, approx. 500ms faster

• Ethernet standards allow for higher range of link-down notification for copper-based links

Fiber Media for Uplinks Significantly

Improves Network Convergence

双环骨干网

注意:思科IE系列交换机,都只有2个千兆光纤接口

我们的应对:

1. 实际光缆布线作业,受环境和成本限制,设计的2条光纤通路往往是同一根光

缆中的2芯或4芯,通常都是共用唯一的布线管道,因此难以避免物理损坏。

2. 环网结构本身就提供了2个不同方向的链路冗余,单点故障对通信无影响。

3. 对于特别重要的工艺环节,建议采用双机双线路的完全双网冗余方案,确保通

信绝对安全。

当前,思科IE系列交换机 不能 支持双环骨干网的组网方式

IP65防护等级含义:完全防尘、向外壳各个方向喷水无有害影响

IP66防护等级含义:完全防尘、向外壳各个方向强烈喷水无有害影

2955防护等级是IP00,全都不防

IE3000防护等级是IP20,防灰(防护12.5mm直径和更大的外来物体),不防水

IP防护等级系统-(INTERNATIONAL PROTECTION)

是由IEC(INTERNATIONAL ELECTRO-TECHNICAL COMMISSION)所起草,将电器依其防尘、防湿气之特性加以分级。

IP防护等级是由两个数字所组成:

• 第1个数字表示电器离尘、防止外物侵入的等级,

• 第2个数字表示电器防湿气、防水侵入的密闭程度,

• 数字越大表示其防护等级越高

超高安全防护等级

超高安全防护等级

• 实际上在工厂环境下,会将自控设备(变频器,PLC)都放在有防护的控制箱内,大部分的自控设备的防护等级也很低,箱体不仅提供防尘防水的保护,而且提供对直流电的裸露接线柱的保护,这样可以将思科工业交换机放在同样的箱子中。

• 相对而言IE3000可在上述环境中直接使用。

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 58

超高安全防护等级

• 需要防尘的环境如炼钢,煤炭,常见问题是由于这些环境中空气中有带电腐蚀颗粒,会腐蚀电路板或造成电路板短路。

防护等级可达到IP43~IP65

• 首钢集团过去一直采用某欧洲厂商的工业交换机解决方案,思科一直与客户多个部门沟通交流,但由于工业客户的使用传统难以改变,替换难度很大。

• 但是2010年在某分厂新型高炉投产时,高炉工业网络出现大面积故障,该欧洲厂商支持不力,使客户设计和技术部门压力巨大。客户决定引入思科作为竞争厂商,避免单一来源技术风险。

• 思科帮助客户分析其网络故障原因是:该欧洲厂商工业交换机仅采用1-2台交换机来管理整个网络,网络收敛速度慢,同时交换机对网络连接状态误判,造成网络始终处于循环震荡状态,造成网络通信中断。客户综合各种故障现象后,非常认同思科对故障的分析判断,也坚定了客户在后续项目中选择思科的信心。

其中高炉网络负责管理高炉炼铁的生产,涉及高温、高压、高金属粉尘的恶劣作业环境,因此技术上要求:

1. 交换机产品质量可靠

2. 网络收敛速度快

3. 组网拓扑灵活,支持复杂的多环嵌套结构

4. 物理端口数量配置灵活

(详细网络拓扑设计参见后页)

客户另一新厂扩建项目中,设计单位选择思科作为工业网络设备提供商,在高炉和水处理2个工艺流程的工业网络采用思科的产品和设计。
