I am using UART for communicating 8 modules having LPC2148 microcontroller as a slave with another module having LPC2148 as master.But I am finding a constraint of wire length(I have read some articles on net which suggest a wire length of 2.6 mtrs for a baudrate of 56000bps) Can I replace this with MODBUS communication ?If yes where can I get information about modbus? ....etc

Atmel Microcontrollers CAN Tutorial


Mature Standard
CAN protocol more than 14 years
Numerous CAN products and tools on the market
Hardware implementation of the protocol
Combination of error handling and fault confinement with high
transmission speed
Simple Transmission Medium
Twisted pair of wires is the standard, but also just one wire will
work
Other links works, too: Opto-or radio links
Excellent Error Handling

Abstract:
Among the various power quality problems, the voltage sags, are attracting a large amount of attention of researchers from industry. DVR gives the solution to the above mentioned problem. The main function of DVR is to mitigate the voltage sag. It controls voltage applied to the load by injecting voltage of compensating amplitude, frequency and phase angle to the distribution line. The DVR is primarily responsible for restoring the quality of voltage delivered to the end user ....etc
