Value, while those parameter objects that are exclusively members of
assembly instance 101 (the COS/cyclic output assembly) will not receive
timeout processing regardless of their Default Enable settings.
This combination of parameter-specific Default Enable and global Timeout
Mode settings allow a relatively complex and specific set of “fail-safe”
behaviors to take place when unexpected failure of the DeviceNet network
occurs.
12.4 General Configuration Procedure
Now that we have had a brief tutorial on parameter and assembly object
assignment and configuration, we can summarize the general overall gateway
configuration process as follows:
1. Enter the console (stops all network communication tasks)
2. Define secondary serial communication settings (physical layer,
protocol and network characteristics)
3. Create DeviceNet parameter objects
4. Assign parameter object memberships to the I/O assembly instances
5. Save the newly-created point database to the gateway’s file system,
and download a copy to your PC for backup purposes
6. Download the customized EDS file for registration in your network
configuration tool
7. Exit the console (resets the gateway)
Of course, it is possible to simplify or even eliminate some of these steps by
starting your configuration from a pre-existing point database file (either
previously-created or downloaded from the internet), and then simply
modifying those elements necessary to match your application.
