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 displayed; click on a register group to select or deselect it for display.
The options are fairly straightforward, but are explained in more detail below.
