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.

Features

 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

 Supports CompactLogix and MicroLogix 1500 LRP Controllers except

1769-QBFC1B, 1769-L16x, and 1769-L18x

Functional Specifications

 ASCII Communication ports 1 & 2 (PRT1. PRT2)

 Both ports are capable of transmitting and/or receiving ASCII character strings.

Each port is individually configurable:

o Stream mode

o Termination character(s)

o Message timeout

o Intercharacter timeout

o Packet size limit

o Baud rate: 110 to 115.2K baud

o Parity: none, even, odd

o Stop bits: 1 or 2

o Data bits: 5 to 8

o RTS on/off timing: 0 to 65535 milliseconds

o Minimum response delay: 0 to 65535 milliseconds

 Handshaking (optional)

o Hardware: RTS/CTS, DTR/DSR

o Software: XON/XOFF

 ASCII character strings up to 4096 characters in length supported

 Full hardware handshaking control provides radio, modem and multi-drop support

 User-definable module memory usage, supporting the storage and transfer of 

up to 4000 registers to/from the control processor

o Module status

o Port error status word (bitmapped)

o Port receive state

o Port receive character count

o Port receive block count

o Port transmit state

o Port transmit character count

o Port transmit block count

 All data related to the module is contained in a single controller tag with defined

objects to simplify monitoring and interfacing with the module

 Module communication data is transferred to the module via a predefined user

data type in the processor
