MVI69E-GSC Generic ASCII Serial Enhanced Communication Module

Features/AdvantagesFeatures/Advantages：

• 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：

  ASCll Communication ports 1&2 (PRT1, PRT2)· 

  Both ports are capable of transmiting and/or receiving ASCll character strings. Each port is individually configurable:

       Termination types

       Stream mode

       Termination character(s)

       Message timeout

       Intercharacter timeout

       Packet size limit

       Baud rate: 110 to 115.2K baud

       Parity: none, even, odd

       Stop bits: 1 or 2

       Data bits:5 to 8· 

       RTS on/off timing: 0 to 65535 milliseconds

       Minimum response delay: 0 to 65535 milliseconds

  Handshaking (optional)

       Hardware: RTS/CTS, DTR/DSR

       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

  Module error and status conditions returned to processor for diagnostic purposes

       Module status

       Port error status word (bitmapped)

       Port receive state

       Port receive character count

       Port receive block count

       Port transmit state

       Port transmit character count

       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
