Timing of RSW1 to 7
Inputs RSW1 to RSW7 are read according to the following timing.
(1) When input changes state from OFF to ON, the time from the
change up to reading is 0.2 s max.
(2) When input changes state from ON to OFF, the time from the
change up to reading is 0.2 s max.

Timing of RSW8 to 12, RUN and PV start
The time from the change in input state up to reading when select-
ing program Nos. by RSW8 to RSW12 is 0.4 s max.
Accordingly, due to the relationship with RUN operation, be sure to
observe timings (1) to (4) in the following diagram.
PV start operation also must conform to RUN operation.
(1) The time from fixing of the selected No. up to the rising edge of
the RUN signal is 0.4 s min.
(2) The time from the rising edge of the RUN signal up to holding
of the program No. is 0.2 s min.
(3) The time from holding of RUN signal OFF up to the rising edge
of the RUN signal is 0.2 s min.
(4) The time from the rising edge of the RUN signal up to holding
of RUN signal ON is 0.2 s min.
(5) The time from fixing of the selected No. up to changing of the
program No. is 0.4 s max.
(6) The time from the rising edge of the RUN signal up to start of
RUN is 0.4 s max.
