13.2.5 Example of sequence program
This paragraph describes a program when the SW
o
D5C-GOTRE-PACK is used.
* The ASCII codes can be displayed on the screen using "ASCII Code Display" or "ASCII Code
Input". indicates space.
• Setting of system information
Read device: D10 (b5 and b6 are occupied.)
Write device: D20 (D24 b5 is occupied.)
• Write destination device and number of devices for bar code setting
Write destination device: D50
Number of devices: 5 (D50 to D54 are occupied.)

• The ON/OFF status of M10 to M17 is trans-
ferred to D10 (b7 to b0).
(M15: Bar code input invalid, M16: Bar code
input read completed)
• The ON/OFF status of D24 (b7 to b0) is trans-
ferred to M27 to M20.
(M25: Bar code input)
• Make this program when the bar code input
should be set invalid.
(Make this program upon necessity.)
• When data is input from the bar code reader,
M25 becomes ON.
ASCII codes are written from the GOT to the
write destination devices (D50 to D54).
(The GOT automatically writes the ASCII
codes. Any program for write is not required.)
• When data input (M25) from the bar code
reader is finished, M16 becomes ON to indi-
cate that read is completed.
Then, the GOT sets M25 to ON, and the next
data can be input.
• In this example, M16 remains ON for 1 sec-
ond.
(While M16 remains ON, next bar code input
data cannot be read.)
