MVI56E-GEC pix

Generic ASCII Ethernet Enhanced Communication Module


The MVI56E-GEC Generic ASCII Ethernet Interface module is designed to allow ControlLogix® processors to interface easily with ASCII devices using the TCP/IP protocol. Compatible devices may be either ASCII instruments with built-in Ethernet or Ethernet connection via a thin server to the existing ASCII device.

Five Servers and Clients are present on the module permitting both the reception and transmission of data between the processor and attached devices.

特性 优势

  • 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.
  • Local or remote rack
