Biff TwinCAT can quickly detect the physical connection and EtherCAT network through emergency scan

This article introduces how to pass Emergency Scan Quickly detect physical connections , testing EtherCAT Network state .

1. Operation process
   1.1. Biff Beckhoff
   1.1.1. scanning IO
   First connect the controller , Set the controller to configuration mode , As shown below
   
   1.1.1. Scan frame test
   The principle is to send the test frame in the configuration mode , Check the frame return , The test steps are as follows ：
   
   Click on Scan The transmission of data frames will be scanned
   
   Finally, if the physical connection of all modules is OK, the sending and receiving frames will be consistent , As shown below
