Hi....
I am working on project in which
I am using RF communication to control machine by sending signals to PLC by Remote(transmitter) and Recevier is connected to PLC....
I checked RF communication..it works great as i can see the output on hyperterminal...I am sending ascii characters for 4 diffrent functions...f for forward , d =down ,l = left ,r= right continuosly....
Transmitter: atmega16 and interfaced with cc2500
Receiver : cc2500 with ttl logic converter
before directly interfacing with serial port of PLC i want to check output on modscan32 s/w....
but i can not see data in modscan even though i see it on hyperterminal....
is there is any diffrence between ascii and modbus ascii...(there are two options in protocol selection in modscan
like modbus ascii and modbus rtu)... how modbus ascii data output looks..means how is it diffrent from the simple ascii....
If so please help me regardnig this ...
