Pattern link
“pattern link” is a function for linking pat-
terns together.
The link destination program No. is set by the
pattern link item.
When the pattern link item is set to 0 (initial
setting), patterns are not linked. When the
No. of the current program itself is set to the
pattern link item, this creates an endless loop.
If the SPs at the link source end point and the
link destination start point do not match, the
SP changes in a stepped manner during link
operation.
When cycle operation has been set, the pat-
tern link function works after cycle operation
has ended. After pattern link operation ends,
operation begins from the No.1 segment of
the link destination pattern, so operation is
restarted with the settings of events 1 to 3 and
time events 1 to 5 cleared.
If PV start is programmed to the link destina-
tion pattern, the PV start function operates
after the link is made.
After the link has been made, PID operation
is not initialized, and is continued.
