6.Steps toward implementing DeviceNet applications using
the command set:
1. Request the use of the Predefined Master/Slave Connection Set.
2. Set the Master’s Explicit Request Messages to set the expected_packet _rate
attribute for the IO connection to establish an I/O Connection Object State
.
3. There are two ways to access IO modules. The first method is by way of the IO
connection object. The other is by using an explicit message to set/get the IO
attribute for the application object.
4. Release the use of the Predefined Master/Slave Connection Set.
