More Information

Overview Manuals Specifications Reduced Data Block Modbus Roles Configuration

Features:

  • Reduced 40-word scheduled ControlLogix data block
  • Two independent Modbus RTU or ASCII serial ports
  • Up to 5000 shared 16-bit registers
ProSoft MVI56E-MCMR is designed for ControlLogix applications where reduced scheduled transfers help manage ControlNet bandwidth.

MVI56E-MCMR lets each serial channel operate independently as a Modbus Master or Slave over RS-232, RS-422, or RS-485.

For MVI56E-MCMR installation, verify remote-rack architecture, serial-interface selection, node addresses, command lists, 40-word transfer handling, database mapping, and backplane current.

The ProSoft MVI56E-MCMR ControlLogix Enhanced Modbus Master/Slave Communications Interface Module with Reduced Data Block is available for quotation, official documentation, and application-matching support from Apter Power.

Description
The MVI56E-MCMR is a ControlLogix enhanced Modbus Master/Slave interface module with a reduced data block. Two independently configurable serial ports can operate on the same or separate Modbus networks. Each port supports Master or Slave operation in RTU or ASCII mode.

The MVI56E-MCMR uses a 40-word scheduled data block to reduce backplane and ControlNet bandwidth. The shared user database contains up to 5000 16-bit registers, and each Master port supports as many as 100 commands. Serial interfaces are selectable between RS-232, RS-422, and RS-485.

The MVI56E-MCMR is intended particularly for remote ControlNet chassis and redundant-controller installations where smaller scheduled transfers are useful. ProSoft Configuration Builder and CIPconnect provide local or remote configuration and diagnostics. For EtherNet/IP applications where bandwidth is not constrained, ProSoft recommends evaluating the MVI56E-MCM instead. Its smaller scheduled transfer is designed to reduce ControlNet loading in remote-rack and redundant-controller architectures.
