4.3 Reading Status Data from the Module
Module status information is useful for troubleshooting and can be accessed in
several different ways.
In the ladder logic's MNET.STATUS controller tag structure.
The MVI56E-MNET module returns status data in the input image that can be
used to determine the module’s operating status. This data is transferred from
the module to the ControlLogix processor continuously as part of the normal data
transfer block sequence (page 113). You can view this data in the
MNET.STATUS controller tag structure in the ladder logic. For more information,
see the Status Data Definition (page 102).
In ProSoft Configuration Builder's Diagnostics screens.
For more information, see the section on PCB Diagnostics (page 96).
In database locations specified by Error/Status Pointers (optional).
If optional Error/Status Pointers are enabled, the status data can also be found in
the Read Data area of the module’s database at the locations specified by the
pointer configuration parameters. For more information, see Backplane
Error/Status Pointer (page 42), Client Error/Status Pointer (page 44) and
Command Error Pointer (page 45).
