Chapter 5. FUNCTIONS

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.
