ATTENTION
Depending on the fieldbus interface application, device operating status and
parameter values may appear as text messages. The text in the table is
typical of values or messages seen when using the NI-FBUS configurator.
Critical Fault
In the case of a critical fault due to Memory Failure, NV/Static data loss or the
readback check failure, writes to the RESTART parameter twice, for the
transmitter to fully recover from the fault condition. Therefore:

2.
3.
4.
Note that if a ROM error (Memory Failure) occurs in the resource block, it
may take up to 10 seconds for the fault to reappear.
