Program example of transient transmission
The following shows a program example of transient transmission.
(1) Overview of program example
In the program example in this section, the following transient transmission is
performed using the READ and WRITE instructions.
(Processing at control station (No. 1)-side)
1) D300 to D349 of the normal station (No. 2) is read to D800 to D849 of the
control station (No. 1) with the READ instruction.
2) D900 to D949 of the control station (No. 1) is written to D400 to D449 of the
normal station (No. 2) with the WRITE instruction.
(Processing at normal station (No. 2)-side)
A sequence program of the normal station (No. 2)-side is not required.
Remark
For the program example of each dedicated instruction, refer to the description of
dedicated instructions. (
