D412 - MVB Diagnostic System

duagon`s MVB diagnostic systems are designed for debugging MVB devices and networks. The diagnostic system is connected to a common PC. The user can operate the diagnostic system in two operation modes:

In the MONITOR mode, the diagnostic system provides a complete set of commands to investigate MVB devices on the bus. Several interactive commands are available on a PC terminal console:

Read and write MVB process data

MVB network investigation with device status poll and scanning of all device ports

Self-learning BA (BA configuration is learned by listening on the MVB bus)

In the SERVER mode, the user applications can be programmed and executed on the PC which is connected to the diagnostic system. A full featured MVB programming library is included in the diagnostic system to control a whole MVB network. The diagnostic system can be used with a common PC:

The D412 is connected through RS232 to the PC

The MVB interface of the D412 complies withthe TCN standard IEC61375. It supports both wire based physical layers being on the market today (selectable by switch):
