6. PROGRAM CONTROL
IMR02L04-E3
6-7
6.3 Search Function
Use the Search function to skip the time of process to the intersection of the Measured value (PV) and the
pattern of the program.
6.3.1 Description of function
Searches the intersection of the pattern and the
Measured value (PV) when the pattern, position
of Hold state and PV are as described in the
right diagram.
The program must be in HOLD
state to conduct Search function.
When finding an intersection: skip the time of process of the program to the intersection.
For Dot display, segments in progress flash. Next the segments of the
intersection will flash.
When no intersection was found: no change in operation occurs.
Search function is available in any time during Program control if in HOLD state.
Scope of search function is within a pattern. It is not possible to search a pattern repeated or linked
by Pattern repeat or Pattern link.
Skip the time of process to the beginning of the soak segment being matched with the Measured
value (PV).
(Refer to page 6-1 for “Soak segment”)
Program control starts from the intersection of the Pattern and Measured value (PV) by releasing
HOLD.
It is also possible to conduct Search function by communication.
For Hold function, refer to 6.5 Hold (HOLD) (P. 6-9).
