1.1.3　plc的分类
plc是应现代化生产的需要而产生的，plc的分类也必然要符合现代化生产的需求。一般来说，可以从3个角度对plc进行分类，即控制规模、控制性能、结构特点

function西门子plc模块代理商上海一级代理

configuration of electrical industrial ethernet line, star andringtopologies

fast redundancy in the ring with:

high speed redundancy protocol (hrp); up to 0.3 secondsforreconfiguration of the ring with 50 switches in thering

profinet mrp (media redundancy protocol); up to 0.2 secondsforreconfiguration of the ring with 50 switches in thering

the functioning of the ring is continuously monitored bytheintegrated redundancy manager. it recognizes failure ofatransmission link in the ring or failure of a scalance xp-200andactivates the substitute path within 0.3 seconds with hrpor0.2 seconds with mrp

use in ring topologies together with scalance x-200, x-300,xm-400and xr-500

redundant connection of rings via hrp standbymaster/slavefunction

uncrossed connecting cables can be used due toautocrossoverfunction integrated in the ports

easy diagnostics using signaling contact, snmp and webbrowser

easy copper cable diagnostics via web browser for localizingcablebreaks

incorporation in the integrated system diagnostics of the tiaportalwith profinet diagnostics of data traffic using aconfigurablemirror port and a commercially available networkanalyzer (e.g. viabusanalyzer agent xm-400)

optimized support of profinet real-time communication (rt)throughprioritizing

fast device replacement in the event of a fault by usingtheoptional c-plug removable data storage medium (not includedinscope of delivery)

networktopology and network configuration西门子plc模块代理商上海一级代理

the scalance xp-200 industrial ethernet switches in ip65 degreeofprotection are typically mounted outside the control cabinet.theycan be installed in line, star and ring electricalsystemtopologies.

when configuring the network, the following boundary conditionsmustbe observed:

length of the twisted pair line between two scalance xindustrialethernet switches:

max. 100 m with ie fc cableandie fc m12 plug pro

ip address:西门子plc模块代理商上海一级代理
the ip address is assigned via the dhcp (dynamic hostconfigurationprotocol). if there is no corresponding server in thenetwork, theip address can be assigned using the supplied softwaretool pst(primary setup tool) or step 7/tia portal.
