Generic Serial ASCII Network Interface Module for PLC

MVI71-GSC

Limited Availability: Product with low inventory remaining. More Info

The Generic Serial ASCII Network Interface Module is a fast and easy way to add two fully configurable ASCII communication ports to the PLC platform without consuming the front port of the processor. This allows the PLC processor to interface with any generic ASCII device such as bar code scanners, weigh scale interfaces, legacy ASCII protocol connections, terminal port emulation and printer drivers. Each port supports the sending and receiving of large ASCII character strings and is individually configurable.

Features and Benefits

The MVI71-GSC module is a single slot, backplane compatible solution for the Rockwell Automation PLC platform. This module has two powerful and fully configurable ASCII communication ports, each supporting the sending and receiving of large ASCII character strings. With the implementation of some supporting ladder logic in the processor, the many different devices supporting ASCII communications can be integrated into the PLC platform.

Applications

The MVI71-GSC module is the ideal solution for the many applications where ASCII character communications must be added to the PLC platform. The MVI71-GSC module can be found in many industrial sectors generally involving the following applications:

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

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.
  • Configuration data obtained through user-defined ladder. Sample ladder file included
