Operation of Rewrite During RUN

How Operation of Rewrite During RUN
The FP0 allows program rewriting even in RUN mode. When a rewrite is attempted
during RUN, the tool service time is temporarily extended, program rewriting is
performed, and operation is resumed without the need to change the mode. For this
reason, the time of the scan during the RUN rewrite extends from several msec to
several hundreds of msec.
Operation During Rewrite
External output (Y) is held.
External output (X) is ignored.
The timer (T) stops the clock.
Rise and fall changes in the inputs of differential instructions (DF), counter instructions
(CT), and left/right shift registers [F119 (LRSR)] are ignored.
Interrupt functions are stopped.
Internal clock relays (special internal relays) are also stopped.
Pulse output is stopped during the rewrite.
Set Values for Timer/Counter Instructions
All set values specified with decimal constants (K) in timer and counter instructions are
preset in the corresponding set value areas (SV). Values in the elapsed value area (EV)
do not change.
Operation of Rewrite During RUN Completed Flag
The rewrite during RUN completed flag (R9034) is a special internal relay that goes on
for only the first scan following the completion of rewriting in the RUN mode. It can be
used instead of the initial pulse relay following a change in the program. (Supported in
CPU Ver. 2.0 and subsequent versions)
