I am using EtherNet/IP to send data between UR and PC. Now , I can successfully send CIP data to UR and get lots of info such as I/O , Tool .
However , I do not know how to set the I/O value of UR from PC ?
By reading UR EDS File , I send cip data to UR ( service=Set_Attribute_single , classID=0x04 , InstanceID=0x70 , AttributeID=0x03 , + request data ) for setting I/O value or Register value . and then I send cip data to UR ( service=Get_Attribute_single , classID=0x04 , InstanceID=0x64 , AttributeID=0x03 ) for getting I/O value or Register value .
However It is inoperative , who can tell me why?
At the same time , the EtherNet/IP light is always yellow , does it need to be green?
At last , what is the function of Connection Manager section in EDS File ?
