InternalFault Triggered on 
the Safety Output Module
Table 58 describes conditions that can trigger InternalFault.
When the conditions that trigger the diagnostics as described in 
Table 58 are 
corrected, the output faults are cleared, the tags and diagnostics reset to 0, and 
the I/O status indicators turn off.

• Output Mode - BIpolar
• Point Operation Type - 
Single
• Point Mode - Safety
• A load is connected 
between a sourcing output 
point and a sinking output 
point.
• O.Ptxx.Data tag = 0
• An overload resistor shorts 
the sourcing output point 
to 0V DC
Faults I.Ptxx.Fault tag = 1 InternalFault = 1
The I/O 
status 
indicator for 
the faulted 
output point 
is steady red.
• Output Mode - Bipolar
• Point Operation Type - 
Single
• Point Mode - Safety or 
Safety Pulse Test
• A load is connected 
between a sourcing output 
point and a sinking output 
point.
• O.Ptxx.Data tag = 0
• Either output point shorts 
to 0V DC
Faults I.Ptxx.Fault tag = 1 InternalFault = 1
• Output Mode - Sourcing
• Point Operation Type - 
Single
• Point Mode - Safety or 
Safety Pulse Test
• O.Ptxx.Data tag = 1
• Output point shorts to 
24V DC
Faults I.Ptxx.Fault tag = 1
IMPORTANT: The tag 
value occurs on the 
faulted output point 
and all of its associated 
group points.
InternalFault = 1
IMPORTANT: The 
diagnostic value occurs 
on the faulted output 
point and all of its 
associated group 
points.
