Modbus RTU, ASCII, and TCP Integration
The range of potential devices and configurations of Modbus serial networks is huge.
While simple serial meters are most common, complex manufacturing machines or PLC
controllers are also possible.
Integration of these devices may involve dealing with different serial environments. One
system’s baud rate may differ, or use Modbus ASCII instead of RTU. MESR protocols
makes it possible for differing Modbus systems to combine into one network, regardless
of technology or communication differences.
