generic ascii ethernet interface module

mvi46-gec

the mvi46 generic ascii ethernet interface module is designed to allow slc processors to interface easily with ascii devices using the tcp/ip protocol and the slc 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 mvi46-gec module is a powerful communication interface for slc platform processors. developed under license from rockwell automation, the module incorporates proprietary backplane technology that enables powerful data access between the module and the slc processor.

general specifications

• single slot – 1746 backplane compatible (local or extended i/o rack only. remote rack not supported)
• the module is recognized as an input/output module and has access to processor memory for data transfer between processor and module using m0/m1 files
• 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

hardware specifications

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 mvi46-gec, the advantage of ethernet speed is realized while allowing greater distances between networked devices. this module provides connectivity to many ascii devices, including applications in:

• bar code scanner interfaces
• weigh scale interfaces
• terminal port emulation
• printer driver (alarm/status printer)
