TableApp.3.2 Special register
Explanation
• The lowest I/O number of the module where the I/O module
verification number took place.
• The first annunciator number (F number) to be detected is
stored here.
• Stores the number of annunciators searched.
• When F goes ON due to
OUT F
or
which go progressively ON from SD64 through SD79 are
registered.
• The F numbers turned OFF by
RST F
SD64 - SD79, and the F numbers stored after the deleted F
numbers are shifted to the preceding registers.
After 16 annunciators have been detected, detection of the
17th will not be stored from SD64 through SD79.
