MSG Status Data Details
The ControlLogix processor may periodically send a MSG request to retrieve the
status data from the MVI56-PDPMV1 module.
The types of data returned in the PROFIBUS Input Status area include:
 Module configuration data values
 MVI56 software revision level
 Key PROFIBUS configuration values
 PROFIBUS Master hardware/software revision level
 MVI56 module statistics
 Mailbox messaging control and status.
You can find the contents of the Status Data block in the MVI56PDPMV1.Status
user controller tag structure in RSLogix. These tags reference the
PDPMV1_Status user-defined data type.
The following table shows the data structure of the GetStatus mailbox response.

PROFIBUS Slave Configured List
This is a 16-byte array with bit fields where one bit is assigned to
each slave station address. The associate bit is set if the slave
is present in the database. For the bit/slave relationship, refer to
the Slave List Structure below.
