Precautions During Programming FP0
8 − 22
8.7 Rewrite Function During RUN
8.7.3 Procedures and Operation of Rewrite During RUN
Item FPWIN GR
Ladder symbol mode
FPWIN GR
Boolean mode
FP Programmer
II
Rewrite procedure Maximum of 128 steps.
Changes are performed by
block.
When PG conversion is ex-
ecuted online, the program
will be rewritten.
Block a Block b
Rewriting performed by step.
Caution is required as rewriting takes place simulta-
neously with the change.
In the case of FP Programmer
II
, the mode must be
changed. (See section 8.7.4.)
Operation of
each
instruction
OT/KP If an instruction written in
block a is deleted in block b,
the condition before the re-
write will be held.
If an instruction written in block a is deleted in block
b, the condition before the rewrite will be held.
Y contact relays which are on will be held in the on
status. To turn them off in the RUN mode, use
forced output.
TM/CT If an instruction written in
block a is deleted in block b,
the condition before the re-
write will be held.
Set values specified by K
constants in TM/CT instruc-
tions are preset in all of the
corresponding SV’s in the
program. (Elapsed values
EV do not change.)
If an instruction written in block a is deleted in block
b, the condition before the rewrite will be held.
Set values specified by K constants in
TM/CT in-
structions are preset in all of the corresponding SV’s
in the program. (Elapsed values EV do not change.)
In the case of FP Programmer
II , set values can be
rewritten during operation without affecting the timer.
For detailed information section 8.8
High-level
instructions
If an instruction written in
block a is deleted in block b,
the condition before the re-
write will be held.
If deleted, the output memory area will be held.
MC/MCE When writing MC/MCE in-
structions, be sure to write
the instructions as a pair.
Writing or deleting a single instruction during RUN is
not possible. Write or delete the instruction in
FPWIN GR ladder symbol mode.
CALL/SUB/
RET
A subroutine is a program
appearing between SUB n
and RET instructions. Be
sure to write it to an address
which follows the ED in-
struction.
Write in the order: RET , SUB , CALL
Delete in the order: CALL , SUB , RET
INT/IRET An interrupt program is a
program appearing between
INT n and IRET instructions.
Be sure to write it to an ad-
dress which follows the ED
instruction.
Write in the order: IRET , INT
Delete in the order: INT , IRET
