5.7.4 Global Output Data
Global Output Data transmitted from the MVI46-MBP module to the network is
located at registers 7090 to 7121 in the module's database. This data is globally
broadcast to all active nodes on the network.
Destination nodes can be configured to accept or ignore incoming data from
specific source nodes. Data is transferred from the processor to the module in
each new output image block. The following table shows the database registers
used by this data.

* x = the slot number in the chassis where the module is installed.
5.7.5 Input File Data
The MVI46-MBP module transfers up to 32 words of data in each new input
image block sent to the processor. Incoming data from each source node can be
indexed into up to eight fields for delivery into separate data destinations in the
receiving node. Nodes configured for global input can request up to 32 words
from each node up to a maximum of 500 words.
The data used to construct is block is determined by the Input File Map data set.
The data transferred to the processor is located in the module's database at
registers 7130 to 7161. The following table describes the register locations for
this data in the module's database:
