Appendix A. Advanced Topics 

Appendix A.1.  Enable the FieldServer to read data from a 90-xx PLC. 

Appendix A.1.1. 

Use 

Versapro 

to configure/look at the EGD 

configuration. 

Produced data must be produced for a specific consumer.  Thus you must create a new 
exchange in the PLC that will produce data for the FieldServer.  (Specific consumer 
means specific IP address). 
 
Since the EGD data packet is not structured, the FieldServer cannot decode the data 
ranges without the Map Descriptors.  It is therefore important that the data ranges in the 
produced exchange correspond to the Map Descriptors in the CSV file. 

 

 Go 

online. 

  View Menu, Hardware Configuration. (Launches HWC program). 

  HWC. Edit. Rack Operations. EGD Configuration. 

 

 

 

  Add an exchange. Set the CONS ADDRESS equal to the IP address of the 

FieldServer.
