Sometimes no blocks show up on device until the address is changed. Why?

[LJGremillion]

We have a been programming single devices on their own Fieldbus segment. Most of the time (95% or more) we have no problems and the new device is placed at address 32 (0x20). Sometimes however, we cannot see the blocks on the new device after the Fieldbus see it come up. Simply changing the address makes the blocks show up. Why is this and can we change the address using the .net tools?

Thanks!

When the new device is added into the network, the host interface will assign a address to it automatically. The address assignment operation is consisted of several steps. Old address->default address->new address.

NI-FBUS .Net API does not have setting address operations. 

Please refer to attached files for the detail information about the troubleshooting of set address problems.
