■ Pattern link
Separate pattern links can be made in CH1 and CH2 programs.
The pattern link function links patterns; the program number of the link at the
destination is set in the pattern link item. An initial value of 0 indicates that linking
is not performed.
When the number of the program is set in the pattern link item, it forms an eternal
loop.
When SP at the end of the original link and SP at the destination are not equal, SP
changes in a step-like manner.
When cycle operation has been set, the pattern link operates after the cycle
operation has been completed.
Since operation starts from the first segment at the destination during pattern
linking, executed values of program items (sequels to settings in the previous
segment) that continue from a previous segment are cleared before program
restart.
When a PV start has been programmed in a pattern at the destination link, the PV
start function operates after the link has been made.
PID computations are not initialized but continued after a link has been
established.
When the READY mode is invoked at the end of an operation or in a RESET
operation, operation returns to program number 1 that is switched from READY to
RUN mode (RUN to READY). If a RESET is performed when a program at the
pattern link destination is reached during an ADV operation in the READY mode,
operation returns to segment 1 of the link destination program number. Note,
however, that program numbers selected using the external switch takes priority.
