7.1 Product Specifications
The MVI69E-MBS allows Rockwell Automation
®
CompactLogix or MicroLogix
1500-LRP
®
I/O compatible processors to interface easily with other Modbus
protocol compatible devices.
The module acts as an input/output communications module between the
Modbus network and the CompactLogix or MicroLogix 1500-LRP backplane. The
data transfer from the CompactLogix or MicroLogix 1500-LRP processor is
asynchronous from the actions on the Modbus 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 or MicroLogix 1500-LRP processors with 1769 I/O
bus capability and at least 500 mA of 5 VDC backplane current available.
