MVI56E-GSC | Prosoft Generic Serial Enhanced Communication Module

Product Overview

The ProSoft MVI56E-GSC is an enhanced generic serial communication module for the Allen-Bradley ControlLogix platform. It provides two fully configurable RS-232/RS-422/RS-485 serial ports with a dedicated RS-232 configuration port, enabling integration of virtually any serial device into a ControlLogix system. The "E" (Enhanced) series features a more powerful processor, larger memory, and advanced diagnostics compared to the legacy MVI56-GSC.

FAQ

Q: What is the difference between MVI56-GSC and MVI56E-GSC?
A: MVI56E-GSC has enhanced processor, larger memory, larger data image, and improved diagnostics. It is backward compatible with MVI56-GSC.

Q: Can I use Modbus RTU with this module?
A: Yes, but it requires custom programming. For native Modbus support, use MVI56E-MCM instead.

Model Selection Tips

• MVI56E-GSC = Enhanced generic serial module for custom protocols
• For standard Modbus RTU/ASCII, use MVI56E-MCM
• For Modbus TCP/IP, use MVI56E-MNETC
• For DF1 protocol, use MVI56E-MNETCR
