
S
: display source device of 7-step display.
D
: start device of
7-step display scan output
n
: polarity setting of output signal and
scan signal.
 8 or 12 continuous external output points that start from this command
D
output 1 or 2 groups of 4 digits of 7-step display by scanning and
display the content of
S
on 7-step display.
n
will decide the
numbers of groups of 4 digits of 7-step display and also indicate the
polaritys of PLC output terminal and 7-step display input terminal.
 The points number of 7-step display output command that a group of 4
digits use is 8 points and 2 groups of 4 digits use are 12 points.
 Scan output terminal will circulate in sequence when this command
executes. The condition contact will be changed from OFF to ON and
scan output execute again.
 Program Example:
Ϩʳ When X10=ON, command will start to execute. 7-step display scan
loop is composed of Y10~Y17. The value of D10 will be converted to
BCD code and send to the first group of 7-step display to display. The
value of D11 will be converted to BCD code and send to the second
group of 7-step display to display. If any value of D10 or D11 is greater
than 9999, operation error will happen.
Ϩʳ When X10=ON, Y14~Y17 will scan in circles automatically. Each circle
scan needs 12 scan time. M1029=ON is a scan period after a circle
scan.
Ϩʳ 4 digits of a group, n=0~3.
 After the terminal of 1, 2, 4, 8 of decoded 7-step display connects
itself in parallet, they should connect to Y10~Y13 of PLC. Latch
terminal of each number connects to Y14~Y17 of PLC individually.
 When X10=ON, the content of D10 will be transmitted to 7-step
display to display in sequently according to Y14~Y17 circulates in
sequence.
Ϩʳ 4 digits of 2 groups, n=4~7.
 After the terminal of 1, 2, 4, 8 of decoded 7-step display connects
itself in parallet, they should connect to Y20~Y23 of PLC. Latch
terminal of each number and the first group share Y14~Y17 of PLC.
 The content of D10 will be transmitted to the first group of 7-step
display and the content of D11 will be transmitted to the second
group of 7-step display to display.
