■ Pattern link
“pattern link” is a function for linking patterns 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 pro-
gram 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 desti-
nation start point do not match, the SP changes in a
stepped manner during link operation.
When cycle operation has been set, the pattern link func-
tion works after cycle operation has ended. After pattern
link operation ends, operation begins from the No.1 seg-
ment of the link destination pattern, so operation is re-
started with the settings of events 1 to 3 and time events
1 to 5 cleared.
If PV start is programmed to the link destination pattern,
the PV start function operates after the link is made.
After the link has been made, PID operation is not ini-
tialized, and is continued.
