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.
