Modbus Ethernet Example Slave

Hi all,

I test the examples of the Modbus library found here: http://sine.ni.com/devzone/cda/epd/p/id/4756.

It works fine.

 

I look at the diagrams to understand operation. I have two questions about the MB Ethernet Example Slave.vi

 

1-I do not understand how and where the slave stores data in arrays (Holding Registers and Coils).

2-I want to display the Modbus frame on the front panel but I do not see where are these data.

 

Thank you in advance.
