5Functions set with parameters
Parameter
Setup of the QXYUNITn
sequencer input n: 1 to 4
output unit
(CR7xx-Q series
only)
Note1) This parameter makes speedy processing of the external output signal by system status variable M_Out etc.
In the program example 1 shown in the following, output signal processing of Steps 1 and 4 gets speedy.
<Program example 1>
1 M_Out(9)=1
2 *ack_check
3 If M_In(7)=0 Then *ack_check
4 M_Out(9)=0
5 End
* Reference value of speed improvement:
In the above-mentioned program example, processing time is reduced about 80%
However, the CC-Link, profibus and parallel I/O interface (card) are effective in case the command of the signal output of two or
more lines is continuing.(CR7xx-D series) In the following program example 2, processing time is reduced about 75%.
<Program example 2>
1 M_Out(9)=1
2 M_Out8(10)=&H1F
3 M_Out16(18)=&H3FFF
4 M_Out32(33)=&H7FFFFFFF
5 End

Always make interlock of signal to take synchronization. Failure to observe this could lead to cause
of malfunction by the signal transmitted incorrectly.
In addition, the "Conventional compatibility mode" is prepared for if needing the same processing
time as the conventional. The initial value of SD series is Conventional compatibility mode. However,
sure under the interlocking of the signal, because of to performance improvement, recommends use
in the High-speed mode
