I/O Traffic Display
When the Server is running and client applications are requesting data, you may view
the sending and receiving of Modbus packets. This is useful for checking what is
happening on the network or for debugging any problems. Select I/O Traffic
Display to choose devices whose communications you wish to see:
The top portion of the I/O Traffic Display dialog box is labeled Display and offers
various options to customize the way messages appear on the screen.
The bottom portion of the dialog box is labeled Device Selection and allows you to
choose the devices for which you’d like to display traffic. The Devices for Display
box lists the devices currently displayed (if display is enabled with the radio button
above). The Register Groups for Display box at the right lists the register groups to
be displayed for the currently selected device. Highlighted register groups are
