The MVI69E-GEC Generic ASCII Ethernet Interface module is designed to allow CompactLogix™ / MicroLogix™ processors to interface easily with ASCII devices using the TCP/IP protocol. Compatible devices may be either ASCII instruments with built-in Ethernet or Ethernet connection via a thin server to the existing ASCII device.
Five servers and Clients are present on the module permitting both the reception and transmission of data between the Rockwell Automation processor and attached devices.
The MVI69E-GEC module is a powerful communication interface for CompactLogix / MicroLogix processors. Developed under license from Rockwell Automation, the module incorporates proprietary backplane technology that enables powerful data access between the module and the CompactLogix / MicroLogix processor.
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 memory and processor controller tags. A sample ladder file with AOI is included
Configuration data obtained from configuration text file downloaded to module.
