Introduction
Modbus communication interface for a multidrop network based on a master/client architecture.
It moniters and program devices to communicate between intelligent devices and sensors and instruments,to monitor the field devices using PCs and HMIs.
Modbus protocol defines a message structure,how pc address a ....etc

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

OBJECTIVE
A summer internship report is a documentation of a student s work a record of the original work
done by the student in the summer internship of 8 week duration.
The objective of this document is to provide a set of guidelines that help a student to prepare the
report to satisfy the requirements of internship report.
The guidelines are general. Student may follow these else any better/ innovative way of presenting
the work done during intern in a form of report is always welcome.
Following is the sequence heading of summer int ....etc
