The Prosoft MVI69E-MBS is a communication module designed specifically for Rockwell Automation’s CompactLogix processors. It enables these controllers to communicate with other devices using the Modbus Serial protocol. Here’s a breakdown of its key features and functionalities:

Core Function:

• Modbus Serial Master and Slave: The MVI69E-MBS acts as either a Modbus Serial Master or Slave, facilitating communication with various Modbus Serial compliant devices.
  • Master Mode: In this mode, the MVI69E-MBS initiates communication, reads data from, and writes data to other Modbus Serial devices on the network. This allows the CompactLogix controller to act as the central control unit, collecting data from and controlling remote devices.
  • Slave Mode: Conversely, when configured as a Slave, the MVI69E-MBS responds to commands from a Modbus Serial Master unit and transmits or receives data based on those commands. This enables integration of the CompactLogix controller into existing Modbus Serial networks.
