Hai friends..
This is my new project. I want to interface scada software with ATMEL ATmega32 microcontroller. Initially i tried with the scada software "Intouch" from Wonderware. But i couldn't setup the communication with the Intopuch scada. When i ask to some experts they told that Intouch scada can't interface with microcontroller because its using some other protocol and communication is possible only by using MODBUS protocol.
So i just went to Citect scada. this will support MODBUS protocol. I download several pdf files and tutorials as far as i can and i tried a lot to communicate with scada. I wrote the program in avr to receive the data from scada and to reply against that implementing MODBUS commands. My AVR hardware can receive the data from scada and when i am transmitting the data the scada doesn't responding. What i will do?? somebody can help me..please..
