ProSoft MVI69E-MBS Modbus Serial Communication Coprocessor Module
MVI69E-MBS is a Modbus serial communication coprocessor module designed by ProSoft for the Rockwell CompactLogix (1769) PLC rack. MVI69E-MBS can achieve protocol conversion between CompactLogix controllers and serial Modbus devices. The dual serial ports can be independently configured as Modbus master or slave, supporting Modbus RTU/ASCII. MVI69E-MBS has independent processing of serial communication tasks and does not occupy PLC scanning cycles; Collect serial data from frequency converters, instruments, weighing controllers, and old RTU devices and upload it to CompactLogix. At the same time, issue PLC control instructions to on-site serial Modbus devices to solve data interoperability between Rockwell PLCs and third-party serial devices. MVI69E-MBS also comes with a debugging network port for module parameter configuration and fault diagnosis.

Product features
- Independent coprocessor architecture, serial communication operations are independently completed by the module, occupying almost no CompactLogix CPU resources and not affecting the PLC scanning cycle.
- Dual isolated serial communication ports, each port can be independently set as a master or slave station, supporting three electrical interfaces: RS232/422/485, and adapting to multiple on-site serial port wiring methods.
- Supports both Modbus RTU and Modbus ASCII protocols, compatible with a large number of old-fashioned serial port instruments and controllers.
- Equipped with AOP additional configuration files and AOI function blocks, directly configured in Studio5000 software, built-in UDT custom data types, simplifying program development.
- Supports non-standard floating-point formats such as Enron and Daniel, and is compatible with special equipment such as flow meters and weighing instruments.
- Equipped with Legacy compatibility mode, it can directly replace the old MVI69-MCM module, and the renovation of old projects does not require large-scale modification of PLC programs.
- Module diagnostic information is directly mapped to PLC tags, allowing real-time viewing of serial communication status and error messages in the program or upper monitoring, facilitating fault location.
- Panel LED indicator lights display module operation, backplane communication, two-way serial communication, and configuration status.
- Equipped with a built-in debugging Ethernet port, the computer can directly access module web pages, monitor communication messages online, and download firmware.
