4.1 Reading Status Data From the Module
The MVI71-DNP module returns a Status Data block that can be used to
determine the module's operating status. This data is located in the module's
database status database and error status list. This data is transferred to the
PLC processor read blocks with an identification code of 100. For a complete
listing of the status data object, refer to the Installing and Configuring the Module
section.
4.1.1 The Configuration/Debug Menu
The Configuration and Debug menu for this module is arranged as a tree
structure, with the Main Menu at the top of the tree, and one or more sub-menus
for each menu command. The first menu you see when you connect to the
module is the Main menu.
Because this is a text-based menu system, you enter commands by typing the
command letter from your computer keyboard in the terminal application (for
example, HyperTerminal). The module does not respond to mouse movements
or clicks. The command executes as soon as you press the command letter —
you do not need to press [Enter]. When you type a command letter, a new
screen will be displayed in your terminal application.
