9.7.3 Procedures and Operation of Rewrite During RUN
Item
FPWIN GR
Ladder symbol mode
FPWIN GR
Boolean mode
Rewrite procedure
Maximum jof 128 steps.
Changes are performed by block.
When PG conversion is executed
online, the program will be
rewritten.
Rewriting performed by step.
Caution is required as rewriting
takes place simultaneously with
the change.
OT/KP
If an instruction written in block a
is deleted in block b, the condition
before the rewrite 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 bill
be held in the on sattus. 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 rewrite will
be held.
• Set values specified by K
constants in TM/CT instructions
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 instructions
are preset in all of the
corresponding SV’s in the
program. (Elapsed values EV do
not change.)
Fun
High-level
instructions
If an instruction written in block a
is deleted in block b, the condition
before the rewrite will be held.
• If deleted, the output memory
area will be held.
MC/MCE
When writing MC/MCE
instructions, 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 SUBn and
RET instructions. Be sure to write
it to an address which follows the
ED instruction.
Write in the order: RET, SUB,
CALL
Delete in the order: CALL, SUB,
RET
Operation
of each
instruciton
INT/IRET
An interrupt program is an
program appearing between INTn
and IRET instructions. Be sure to
write it to an address which follows
the ED instruction.
Write in the orde: IRET, INT
Delete in the order: INT, IRET
