Generic ASCII Ethernet Communications Interface Module
MVI56-GEC
The MVI56 Generic ASCII Ethernet Interface module is designed to allow ControlLogix processors to interface easily with ASCII devices using the TCP/IP protocol and the ControlLogix 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 MVI56-GEC module is a powerful communication interface for ControlLogix platform processors. Developed under license from Rockwell Automation, the module incorporates proprietary backplane technology that enables powerful data access between the module and the ControlLogix processor.
General Specifications
- Single Slot - 1756 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
- Local or remote rack
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 MVI56-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)
