Explicit Messaging (DNI Series B Only) 79
The DNI can store up to 10 profiles. These profiles can be changed at
any time, and they are not backed up with a battery. If the power to
the DeviceNet network is lost, the profiles are cleared and must be
reloaded. This can be done with a subroutine.
Routing Profile
Configuration The 10 profiles are stored within the DNI in profile registers. To
configure a routing profile, the user creates a write message in the
controller’s ladder logic with a destination node address of 240…249.
The write message must have a data length of five words. Each word
corresponds to one of the five components in the routing profile.
When the DNI receives a write message with a destination address of
240…249, it stores the five words of data in the corresponding profile
register, location 240…249.
TIP
A message instruction returning an error code of
0xD0H is an indication that profiles need to be
re-configured.
