I have an alarm module(Adam 6066). I would like to communicate with this module from my c++ program. I am working on Windows platform. I have read the manual and it says it supports Modbus/TCP, TCP, UDP protocols. I am not sure how to start with it. Any suggestions or sample code will be of great help.

which means you can communicate with the device though sockets to read/write data to it.
 
The normal procedure is go through their manual on how to configure your device, the manual will also have sample code/application how to read/write to the device.
 
You might need to implement a socket communication program in your application to read/write data to your device. take a look at this article[^] on socket programming in C++. Also refer the manual for how to send/receive data

The manual has sample code in Java and C# .net but nothing in c++. So, if i use socket programming to communicate with the device it should work right?

you will have to know how to convert other programming language to your preferred language and no one will teach you that

Yes its just the string commands to send across. If you refer the manuals and C# or Java samples you can do that effortlessly. and again if you have any trouble CP is ready to help you so no worries Good Luck.

Thank you. That is really motivating. I will work on this and if i have any doubts will post it here.
MODBUS is a relatively simple protocol. The first two entries of a Google quick search are two useful documents: I've got the CRC implementation (C source code) from the first one: "Modicon
Modbus Protocol - Reference Guide"[^] and used the second one, namely: "MODBUS APPLICATION PROTOCOL SPECIFICATION"[^] as reference.
