Generic ASCII Ethernet Network Interface Module for PLC

MVI71-GEC

Disponibilidad Limitada: Producto en stock limitado. More Info

The Generic ASCII Ethernet Network Interface Module (MVI71-GEC) allows PLC processors to connect to any generic ASCII device such as bar code scanners, weigh scale interfaces, legacy ASCII protocol connections, terminal port emulation and printer drivers. The use of the TCP/IP protocol at the device level on the plant floor has become widespread. The MVI71-GEC takes advantage of Ethernet’s speed while also allowing greater distances between networked devices.

Características y Beneficios

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 Rockwell Automation PLC 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.

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)

Support for PLC processor programming over Ethernet using a TCP/IP service and a serial port on the module connected to channel 0 of the processor. The module's third port emulates Channel 0 of the processor to pass through messages from the port to the processor

Server Specifications

  • Supports EtherNet/IP explicit, connected, and unconnected class messaging
  • Twenty independent server connections permit remote clients to interact with all data contained in the module
  • Data can be derived from other clients on the network, through the client on the module, or from the PLC processor

Client Specifications

  • Actively issues connected, explicit messages to other nodes on the network
  • Supports 100 user-defined commands from a single client
  • Allows command control from ladder logic
  • Pass-through services
  • Permits remote programming of the PLC processor on the Ethernet network via a pass-through
  • TCP/IP service and a serial communication port (pass-through port) on the module
  • The third port on the module can emulate the Channel 0 port on the PLC, This allows a DF1 master device attached to the emulated (Channel 0) port to monitor and control data in the PLC.
