Chapter 6. OPERATION
■
Read timing
●
Timing of inputs RSW1 to 7
Inputs RSW1 to RSW7 are read according to the following timing.
1
When input state changes from OFF to ON, the time from the change up to
reading is 0.2 seconds max.
2
When input state changes from ON to OFF, the time from the change up to
reading is 0.2 seconds max.
●
Timing of inputs RSW8 to 12, RUN and PV start
The time from the change in input state up to reading when selecting program Nos.
by RSW8 to RSW12 is 0.4 seconds 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 seconds min.
2
The time from the rising edge of the RUN signal up to holding of the program
No. is 0.2 seconds min.
3
The time from holding of RUN signal OFF up to the rising edge of the RUN
signal is 0.2 seconds min.
4
The time from the rising edge of the RUN signal up to holding of RUN signal
ON is 0.2 seconds min.
5
The time from fixing of the selected No. up to changing of the program No. is
0.4 seconds max.
6
The time from the rising edge of the RUN signal up to start of RUN is 0.4
seconds max.
Handling Precautions
When operating the DCP32 by external switch inputs, operation can be
carried out more reliably if a margin is added to the minimum time for the
above read timings.
