2.4. ESD file, GSD file​

 

Each fieldbus device has its own characteristics file for its identification. For DeviceNet or Interbus devices, it is the EDS file (though the file format is different between the two), while for Profibus-DP devices, it is the GSD file. The Hi5 controller also has an EDS file and a GSD file.

 

When registering the characteristics file to network control S/W and executing network browsing, devices connected to the Fieldbus network are detected. The network control S/W downloads this information to the fieldbus scanner module of PLS, which is the master. When network information is downloaded to the scanner module, the PLC scanner module operates the entire network without any help from the network control S/W.

 

Please refer to the manuals for the PLC product and the network setting S/W for details regarding this procedure.
