11.4 Rewrite Function During RUN

11.4.1 Operation of Rewrite During RUN
How operation of rewrite during RUN is performed
Rewriting programs can be executed 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 ms to several hundreds of ms.
Operation during rewrite
1. External output (Y) is held.
2. External input (X) is ignored.
3. The timer (T) stops the clock.
4. Rise and fall changes in the inputs of differential instructions (DF), counter instructions (CT), and
left/right sift registers are ignored.
5. Interrupt functions are stopped.
6. Internal clock relays (special internal relays) are also stopped.
7. 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 complete flag
The rewrite during RUN complete 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.
