I want to know how the modbus/tcp message format would be for some PLC application. Please can any one tell that exact format and explanation of each of these fields.

Here's a link to the guys who wrote the protocol;

Navigate to "Product Manuals" > "Networking" > "Modbus" and download "PI-MBUS-300 Modbus Protocol Reference Guide"
