7.1 Product Specifications
The MVI69E-MBTCP allows Rockwell Automation ® CompactLogix ® processors to
interface easily with other Modbus TCP/IP compatible devices.
The module acts as an input/output communications module between the
Modbus TCP/IP network and the CompactLogix backplane. The data transfer
from the CompactLogix processor is asynchronous from the actions on the
Modbus TCP/IP network. Databases are user-defined and stored in the module
to hold the data required by the protocol.
 Single-slot, 1769 backplane-compatible
 The module is recognized as an Input/Output module and has access to
processor memory for data transfer between processor and module.
 Ladder Logic is used for data transfer between module and processor.
Sample Add-On Instruction file included.
 Configuration data obtained from and stored in the processor.
 Supports CompactLogix processors with 1769 I/O bus capability and at least
500 mA of 5 Vdc backplane current available.
