1.2.1 Exec. V. 1.10 vs. V. 1.20
Exec. V. 1.20 changed the behavior of certain I/O bases if a field side fault
occurred. This change affects the following bases.
H 170 ADM 350 10

170 ADM 350 11
H 170 ADM 390 10

170 ADM 370 10
The following table describes the differences between the two versions in more
detail. Refer to the TSX Momentum I/O Base User Guide (870 USE 002 00) for

If one of the field side outputs faults
(shorts out), the host will read all inputs
as zeros, regardless of the input signal
state.
Version 1.10
170 ADM 390 10
If one of the field side outputs faults
(shorts out), the host will read all inputs
as zeros, regardless of the input signal
state.
If an open condition exists (unconnected)
on any of the input points, the host will
read all inputs as zeros, regardless of the
input signal state.

170 ADM 370 10 If one of the field side outputs faults
(shorts out), the host will continue to read
the inputs normally.
Version 1.20
170 ADM 390 10
If one of the field side outputs faults
(shorts out), the host will continue to read
the inputs normally.
If an open condition exists (unconnected)
on any of the input points, the host will
read
H open inputs as zero (fault) and
H remaining non–faulted inputs normally.
