5.5 Fault Locating References
The Fault-Locating References for a PNC001 module can be used for rack-level and slot-level faults. These
names can be programmed on the FAULT and NOFLT contacts:
• #RACK_000r
• #SLOT_0rss
where r represents the rack number and ss represents the slot number
These names cannot be used to check for faults on a PROFINET IO-Device, remote module, or remote sub-
module.
The reserved fault names are always available. These fault names do not correspond to %SA, %SB, %SC, or to
any other reference type. They are mapped to a memory area that is not user-accessible.
Fault Locating References are not supported by embedded PROFINET Controllers.
