5.1 Product Specifications
The MVI46 PROFIBUS DP Slave Communication Module allows Rockwell
Automation SLC I/O compatible processors to interface easily with a PROFIBUS
DP Master device.
5.1.1 Features and Benefits
The PROFIBUS DP Slave protocol driver supports the PROFIBUS V0 Slave
implementation, providing powerful data transfer capability between the module
and SLC processors. User configurable data mapping and DP port operation
make the interface an easy to use and powerful data transfer tool.
The MVI46 module Configuration/Debug Serial port connects a PC to the module
for configuration, status, monitoring, and troubleshooting (Serial cable is included
with product shipment). After editing on a PC, a configuration file is downloaded
and stored on the MVI46 module.
The PROFIBUS DP Slave gives access to the unit's input and output images with
up to 244 bytes of Input and Output data, for a maximum of 400 bytes total.
These Input and Output data blocks are mapped by the user within the inRAx
module's data memory allowing maximum flexibility and data transfer with other
protocols.
