I have an existing system in which I am sarisfactorily reading some drives run feedback using M340 PLC and citect scada. Now I want to give run command to drive using scada i.e. generating particular DO. For this I have made logic in unity pro and simulated it satisfactorily but when I give command using my scada page nothing happens i.e. no command passes to PLC. Can anyone tell me what could be the problem?

How are you triggering the command from SCADA ?
 
I have created a button on scada page and in up command section I have entered tag_name=1
Address of tag in unity pro is %M251
Address of tag in citect is 0252
