• One 2-pole M12 interface (D-coded) as console access

The SCALANCE XP-200 switches are available with the following port types:

• 10/100 Mbps, M12 connection (D-coded);
  automatic detection of the data rate (10 or 100 Mbps), with autosensing and autocrossover function for connection of IE FC cables via IE FC M12 plug PRO 2x2 up to 100 m.

• 10/100/10 000 Mbps, M12 connection (X-coded);
  automatic detection of the data rate (10 or 100 or 1 000 Mbps), with autosensing and autocrossover function for connection of IE FC cables via IE FC M12 plug PRO 4x2 up to 100 m.

Function西门子PLC模块代理商上海一级代理

• Configuration of electrical Industrial Ethernet line, star and ring topologies

• Fast redundancy in the ring with:

• High Speed Redundancy Protocol (HRP); up to 0.3 seconds for reconfiguration of the ring with 50 switches in the ring

• PROFINET MRP (Media Redundancy Protocol); up to 0.2 seconds for reconfiguration of the ring with 50 switches in the ring

• The functioning of the ring is continuously monitored by the integrated redundancy manager. It recognizes failure of a transmission link in the ring or failure of a SCALANCE XP-200 and activates the substitute path within 0.3 seconds with HRP or 0.2 seconds with MRP

• Use in ring topologies together with SCALANCE X-200, X-300, XM-400 and XR-500

Redundant connection of rings via HRP standby master/slave function

• Uncrossed connecting cables can be used due to autocrossover function integrated in the ports

• Easy diagnostics using signaling contact, SNMP and web browser

• Easy copper cable diagnostics via web browser for localizing cable breaks

• Incorporation in the integrated system diagnostics of the TIA Portal with PROFINET diagnostics of data traffic using a configurable mirror port and a commercially available network analyzer (e.g. via BUSANALYZER AGENT XM-400)

• Optimized support of PROFINET real-time communication (RT) through prioritizing

• Fast device replacement in the event of a fault by using the optional C-plug removable data storage medium (not included in scope of delivery)

Network topology 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 degree of protection are typically mounted outside the control cabinet. They can be installed in line, star and ring electrical system topologies.

When configuring the network, the following boundary conditions must be observed:

• Length of the twisted pair line between two SCALANCE X Industrial Ethernet switches:

• Max. 100 m with IE FC cable and IE 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 Host Configuration Protocol). If there is no corresponding server in the network, the IP address can be assigned using the supplied software tool PST (Primary Setup Tool) or STEP 7/TIA Portal.

Commissioning and diagnostics

PROFINET diagnostic interrupts from SCALANCE XP-200 switches can be displayed with the appropriate SIMATIC engineering tools and processed in the PLC with the enhanced diagnostic function. The engineering outlay for the PLC and HMI has been drastically reduced due to the complete integration in the SIMATIC concept for system error messages.

SCALANCE XP-200 Industrial Ethernet switches can also be integrated in a network management system (e.g. SINEC NMS) using the standardized Simple Network Management Protocol (SNMP). In the event of faults in the device, error messages (SNMP traps) can be sent to a network management system (e.g. SINEC NMS) or as an email to a specified network administrator.

The integrated web server enables configuration and diagnostics settings to be made using a standard web browser (e.g. port configuration). Statistical information can also be read out over the web server (e.g. port capacity utilization).

The following information is displayed on site by LEDs:

• Power

• Port status

• Data traffic

• Signaling contact

• Redundancy manager function

The Industrial Ethernet switches of the SCALANCE XP-200 line can also be monitored using the floating signaling contact.

因为这些都是作为PLC的接口设备接到PLC端口上去的，它们的状态与PLC程序是息息相关的。但是，从程序要求来看，没有必要去专门先学习这方面的课程，而是应该是用到就学、边学边用。待到一定程度后，再系统地学习一下，效果会*好。辑代数是从数学的角度来研究客观事物“真”与“假”之间的逻辑推理关系。在继电控制和PLC多学员都有这样的感觉，当从事某一项新的工作时，总感到自己缺乏系统的理论知识和丰富的实践知识。那么怎么办？一个字：学。理论知识可以系统地学，学习之前，应向周围的同行、同事去问一下，应学习哪些知识，有哪些书可以阅读，有没有系统的培训等。这样可以少走弯路，*学要还是靠自己。PLC的输入／输出系统功能完善，性能可靠，能够适应各种形式和性质的开关量和模拟量的输入／输出。PLC的功能单元能方便地实现D/A、A/D转换以及PID运算，实现过程控制、数字控制等功能。它还可以和其他计算机系统、控制设备共同组成分布式或分散式控制系统，能够很好地满足各种控制的需要。
5．设计、施工、调试的，维护方便西门子PLC模块代理商上海一级代理
继电器接触器控制系统中的中间继电器、时间继电器、计数器等电器元件，在PLC控制系统中是以“软元件”形式出现的，并且又用程序代替了硬接线，因此安装接线工作量少；工作人员也可提前根据具体的控制要求在PLC到货之前进行编程，大大地缩短了施工工期。
PLC体积小、重量轻，便于安装。PLC具有完善的自诊断及监视等功能，对于其内部的工作状态、通信状态、I/O点状态、异常状态和电源状态都有显示。工作人员通过它可以查出故障原因，便于迅速处理。
