Application

The switches of the SCALANCE XC-100 product line support the inexpensive construction of Industrial Ethernet line or star topologies with switching functions for machine level applications. They are designed for installation in the control cabinet. The devices are approved for ATEX Zone 2 and IECEx, which allow them to be used in hazardous areas. The SCALANCE XC108 also has E1 approval, making the products especially suitable for use in public transportation vehicles. Furthermore, the SCALANCE XC-100 product line features various approvals for shipbuilding applications.

Design

The SCALANCE Industrial Ethernet switches with enclosure rear sections of metal are optimized for mounting on a standard DIN rail and an S7-1500 DIN rail. Direct wall mounting in various positions is also possible. Thanks to the enclosure dimensions that correspond to those of the SIMATIC S7-1500, the devices are ideally suited for integration into automation solutions and mounting on the SIMATIC S7-1500 DIN rail. Mounting on a SIMATIC S7-300 DIN rail is also possible.

The SCALANCE XC-100 switches feature:

  • A 4-pin terminal block for connecting the redundant supply voltage (2 x 24 V DC)

  • A raised row of LEDs for displaying status information (power, link status, data communication, signaling contact)

  • A 2-pin terminal block for connecting the floating signaling contact

  • A SET button for on-site configuration of the signaling contact

The following port types are available:

  • 10/100BaseTX, RJ45 port;
    automatic detection of the data rate (10 or 100 Mbps), with autosensing and autocrossover function for connecting IE FC cables via IE FC RJ45 Plug 180 over distances up to 100 m

  • 100BaseFX, ST/BFOC port;
    for direct connection to the Industrial Ethernet glass FOC up to 5 km

  • 100BaseFX, SC port;
    for direct connection to the Industrial Ethernet glass FOC up to 5 km

    Function

    • Construction of electrical and optical Industrial Ethernet line or star topologies

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

    • Load disconnection through integral switch functionality

    • Easy network configuration and network expansion
      No limitation of the expansion of the network when switches of the SCALANCE XC-100 product line are cascaded

    Network topology and network configuration

    The SCALANCE XC-100 switches are typically installed with the stations to be connected in a control cabinet. They can be mixed electrically and optically in star and line topologies.

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

    • Length of the twisted pair line between two SCALANCE XC switches:

      • Max. 100 m with Industrial Ethernet FastConnect products

    • Length of the optical cables:西门子一级代理商PLC模块代理

      • Max. 5 km with Industrial Ethernet glass fiber-optic cables

    Star-shaped network topology with SCALANCE XC124

    Electrical and optical line topology with SCALANCE XC106-2 and XB004-2 as well as connection and supply of data terminal devices with Power over Ethernet (PoE) by SCALANCE X108PoE

    Diagnostics

    The following information is displayed on site by LEDs:

    • Power

    • Port status

    • Data traffic西门子一级代理商PLC模块代理

    The Industrial Ethernet switches of the SCALANCE XC-100 line can also be monitored using the floating signaling contact.

    1.和S7-200 PLC相比,S7-200 SMART PLC信号板配置是特有的,在功能扩展的同时,也兼顾了安装方式,配置灵活,且不占控制柜空间。
    2.读者在应用PLC及数字量扩展模块时,一定要注意针脚载流量,继电器输出型载流量为2A;晶体管输出型载流量为0.7**。在应用时,不要*过上限值;如果*限,则需要用继电器过渡,这是工程中常用的手段。
    (4)模拟量扩展模块
    模拟量扩展模块为主机提供了模拟量输入输出功能,适用于复杂控制场合。它通过自带连接器与主机相连,并且可以直接连接变送器和执行器。模拟量扩展模块通常可以分为3类,分别为模拟量输入模块、模拟量输出模块和模拟量输入/输出混合模块。
    模拟量输入模块有2种,分别为2路输入和4路输入,SM421对应型号为EM AE04和EM AE08,量程有4种,分别为±10V、±5V、±2.5V和0~20mA,其中电压型的分辨率为12位+符号位,满量程输入对应的数字量范围为-27648~27648,输入阻抗≥9MΩ;电流型的分辨率为12位,满量程输入对应的数字量范围为0~27648,输入阻抗为250Ω。相关设备是为了充分和方便地利用系统硬件和软件资源而开发和使用的一些设备,主要有编程设备、人机操作界面等。
    ① 编程设备主要用来进行用户程序的编制、存储和管理等,并将用户程序送入PLC中,在调试过程中,进行监控和故障检测。S7-200 SMART PLC 的编程软件为STEP 7-Micro/WIN SMART。
    ② 人机操作界面主要指*操作员界面。常见的如触摸面板、文本显示器等,用户可以通过该设备地完成各种调整和控制任务。1.2 S7-200 SMART PLC的CPU模块外部结构及外部接线 CPU模块的外部结构
