SEL1200/1400直流分路保护模块 与 SIMATIC系列PLC的DI通道连接建立通信,这里提供了通信必备的功能块和WinCC预制面板(博图库文件)

The selectivity modules SITOP SEL1200 and SEL1400 have a diagnostic interface "COM" whose signal can be evaluated via a digital input in a high-lever controller, e. g. S7-1200 CPU and S7-1500 CPU.


The diagnostic interface "COM" of the SEL1200 and SEL1400 provides a signal that transmits the following device data as a Manchester code:

  • Status information
  • Current output current values at the outputs
  • Current limit values at the outputs
  • Device information


Solution

The following library provides function blocks for SIMATIC S7-1200, S7-1500 and S7-300/S7-400 as well as faceplates for SIMATIC Comfort Panels. The function blocks enable you to read in and evaluate the signal of the diagnostic interface "COM" via a digital input at the S7-CPU. You can use the faceplates to clearly display the device data on an HMI control panel.

Note

  • The library blocks for SIMATIC S7-1500 can also be used in an ET 200SP CPU and ET 200pro CPU.
  • The library blocks for SIMATIC S7-300/S7-400 can also be used in an ET 200S CPU and ET 200pro CPU.

The following figure shows the graphic representation of the solution.
