Communication Status
Once you install the network and program the master, you can use the LEDs and equipment parameters to identify
some states related to communication.
The LEDs ”NET” and ”Link” provide information about the state of the interface and communication.
The parameter P0751 indicates the status of communication between the device and the network master.
The network master must also provide information about the communication with slave.

Operation Using Process Data
Once the communication is established, the data mapped in the I/O area is automatically updated between master
and slave. Among the main parameters that can be used to control the device, we can mention:
P0680 - Status Word (read)
P0682 - Control Word (write)
It is important to know these parameters to program the master as desired for the application.
