Reading Status Data from the Module .................................................. 37
LED Status Indicators............................................................................ 47
The module provides information on diagnostics and troubleshooting in the
following forms:
Status data values are transferred from the module to the processor.
Data contained in the module can be viewed through the
Configuration/Debug port attached to a terminal emulator.
LED status indicators on the front of the module provide information on the
module's status.

Reading Status Data from the Module
The MVI56-3964R module returns a 31-word Status Data Block (page 65) that
may be used to determine the module's operating status.
This data is transferred to the ControlLogix processor every time the module
does not have 3964R communication data to send to the processor.
The Configuration/Debug port provides the following functionality:
Full view of the module's configuration data
View of the module's status data
Version
Information
Control over the module (warm boot, cold boot, transfer configuration)

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:
80486 based processor (Pentium preferred)
1 megabyte of memory
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.
A null modem serial cable.
