The module provides information on diagnostics and troubleshooting in the
following forms:
 LED status indicators on the front of the module provide information on the
module’s status.
 Status data contained in the module can be viewed in ProSoft Configuration
Builder through the Ethernet port.
 Status data values are transferred from the module to the processor.
3.1 Reading Status Data from the Module
The MVI56E-GSC module returns three separate status data areas to the
ControlLogix processor in each read block. This data is transferred to the
ControlLogix processor continuously with each read block. For a complete listing
of the status data object, refer to the Module Configuration section of this
manual.
This guide also includes example ladder logic showing how to extract this data
from the input image and place it in the module’s Controller Logic Tag. Refer to
Diagnostics and Troubleshooting for a discussion of the features available
through the use of this utility.
