Network-Specific Information 

This section will discuss topics that are specific to each of the available 
primary and secondary network selections.

Table 8 outlines the objects supported within the device.  For more 
specific details regarding the attributes and services supported by each 
object, refer to the separately-provided ODVA Statement of Conformance 
(SOC).

All secondary network objects that are to be accessed must be defined as 
DeviceNet parameters objects.  Access is then available either via explicit 
messaging or via membership in an IO assembly object. 

 

•

 

DeviceNet object, BOI attribute: This attribute value is saved in the 
gateway’s internal nonvolatile memory.  If the BOI value is set to TRUE, 
the gateway will attempt to restart the network interface on the occurrence 
of a CAN bus-off event.  This will continue to be the behavior until the Bus-
Off Counter attribute achieves a value of 255.  If a CAN bus-off event 
occurs after this point, the gateway will not attempt to restart the network 
interface: it will remain faulted and isolated from the network until reset 
(power removed from the unit or a console “exit” performed). 

 

•

 

If any gateway characteristics are modified in the course of configuration, 
remember to always download a new EDS file to your computer and re-
register it with your network configuration tool. 

 

•

 

During I/O data exchanges, if the actual consumed data size is less than 
or equal to the connection instance’s configured consumed connection 
size, then all received data will be consumed and the connection will 
produce normally.  If the actual consumed data size is larger than the
