Rockwell Automation 1336T Function Block Prog. Manual, Series A/B - Manual (Page 171)

6–9 Handling Exceptions — Faults and Warnings
1336 FORCE — 5.9 August 1995
Word 5 of the function block fault status returns the destination
parameter or node holding the invalid link.
For example, if you issue a Fault Status Read request and the drive
response indicates that word 4 is 200
Hex
and word 5 is 183
Hex
(387
Dec
), an invalid link occurred at parameter 387
Dec
. You need to
adjust the link to parameter 387 before you can clear the fault queue.
To adjust the link, you can:
❒
Clear the link with a Clear All FB Links command.
❒ Clear the link by writing a source value of 0.
❒
Reconnect the parameter to a valid parameter or node.
Once you adjust the link, you need to issue a Process All FB Links
command to re–check the the function block links.
Clear Faults Command
The system Clear Faults command initiates the Process All FB Links
service. If no other illegal links are found, the system fault is cleared
and drive enable is allowed.
