The Transient Manager Object (class code 0x38C) defines the setup of
transient data acquisition mode and provides access to the associated transient
data buffers. Furthermore this object allows for transient type definition,
which can differentiate between normal and fast transients.

*The last transient event timestamp comprises two UDINT - sub-second resolution to one nanosecond followed by
seconds since 1970.
When transient capture is enabled it indicates the last detected transient event (since power-up) irrespective of
whether this is captured or stored by the module. For example the time stamp may be updated by a more recent
coast down where only run-ups are stored or by a transient event that occurs after all buffers have been used and
latched.
