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
(default), 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 pattern 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 effective value
(setting of previous segment
continued) of the program item (e.g.
PV event value, PID set No.) whose
setting is continuous from the
previous segment 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 initialized, and is
continued.
Pattern link functions simultaneously
on both patterns of SP1 and SP2.
■
Tag
A “tag” is eight alphanumeric data that can be set to each program.
Though this item cannot be displayed nor set on the DCP32, it can be displayed and set on the smart loader
package.
When the pattern items of segment 1 has been set by program setup, a total of eight characters (“PROG” +
program No. (2 characters) + “__” (two spaces)) are automatically set.
Example:
In the case of program No.1:
“
PROG01__
”
In the case of program No.19: “
PROG19__
”
