Generic ASCII Ethernet Communications Module

MVI71-GEC

The MVI71 Generic ASCII Ethernet Interface module is designed to allow PLC processors to interface easily with ASCII devices using the TCP/IP protocol and the PLC processor. Compatible devices may be either ASCII instruments with Ethernet built-in or Ethernet connection via a thin server to the existing ASCII device.

Features and Benefits

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 MVI71-GEC module is a powerful communication interface for PLC platform processors. Developed under license from Rockwell Automation, the module incorporates proprietary backplane technology that enables powerful data access between the module and the PLC processor.

General Specifications

  • Single Slot - 1771 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 ladder file included.
  • Configuration data obtained from configuration text file downloaded to module. Sample configuration file included.

Applications

The use of the TCP/IP protocol with Ethernet at the device level on the plant floor is becoming widespread in many industry segments. Using the MVI71-GEC the advantage of Ethernet speed is realized while allowing greater distances between networked devices.

  • Bar code scanner interfaces
  • Weigh scale interfaces
  • Legacy ASCII protocol connections
  • Terminal port emulation
  • Printer driver (alarm/status printer)
