™ Reading Status Data from the Module .................................................. 45
™ LED Status Indicators............................................................................ 60
The module provides information on diagnostics and troubleshooting in the
following forms:
ƒ Status data values are transferred from the module to the processor.
ƒ Data contained in the module can be viewed through the
Configuration/Debug port attached to a terminal emulator.
ƒ LED status indicators on the front of the module provide information on the
module's status.
4.1 Reading Status Data from the Module
The MVI69-DFCM module returns a 29-word Status Data block that can be used
to determine the module's operating status. This data is located in the module's
database at registers 7600 to 7628 and at the location specified in the
configuration. This data is transferred to the CompactLogix or MicroLogix
processor continuously with each read block.
4.1.1 Required Hardware
You can connect directly from your computer's serial port to the serial port on the
module to view configuration information, perform maintenance, and send
(upload) or receive (download) configuration files.
ProSoft Technology recommends the following minimum hardware to connect
your computer to the module:
ƒ 80486 based processor (Pentium preferred)
ƒ 1 megabyte of memory
ƒ At least one UART hardware-based serial communications port available.
USB-based virtual UART systems (USB to serial port adapters) often do not
function reliably, especially during binary file transfers, such as when
uploading/downloading configuration files or module firmware upgrades.
ƒ A null modem serial cable.
4.1.2 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.
