Restoring the Remote Indicator to default settings

Remote Indicator Diagnostics

Remote Indicator faults are grouped into one of these two diagnostic categories and could cause the
following results:
Critical and Non-Critical Fault  Remote Indicator continues to read PVs from other
1.
Remote Indicators connected to the RMA803.
Block Configuration Errors  Incorrect parameter values causes the Remote Indicator to
2.
generate a fault, for example, BLOCK_ERR or MODE_BLK = OOS.

Function Block Faults

Checking the status and values of key block parameters helps in identifying the type of function
block fault whether it is critical or non-critical.
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
Remote Indicator to fully recover from the fault condition. Therefore:
1.
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.
Revision 4 Foundation Fieldbus RMA803 Remote Indicator User's Guide
Write "4" or "restart processor" to RESTART parameter of resource
block.
Wait until communication is established.
If the fault occurs again, repeat the write to the RESTART parameter.
If the fault occurs again, replace the Remote Indicator electronics
module.
